Quick answer

Xero enforces strict API rate limits to protect their servers from overload. You get 60 calls per minute and 5,000 daily calls per organization. Hit these limits? Your app stops working.

Most businesses struggle with these constraints when pulling financial data. Automated reports break. Dashboard updates fail. Manual workarounds eat up hours.

Coefficient solves this problem. Our smart caching and optimized sync protocols work within Xero’s limits while keeping your data fresh. Connect once, pull unlimited reports, and never worry about rate limits again.

Xero rate limits

API Rate Limits

• Concurrent Limit: 5 API calls in progress at a time (per-organization, per-app)
• Minute Limit: 60 API calls per minute (per-organization, per-app)
• Daily Limit: 5,000 API calls per day (per-organization, per-app)
• App-wide Minute Limit: 10,000 calls per minute across all tenancies for a single app

API Usage Limits

• Per Organization: All rate limits are enforced per Xero organization (tenant) per connected app instance
• Uncertified Apps: Limited to 25 concurrent organization connections (no limit for certified apps)
• Payload Size: Max 3.5MB for a single POST to Accounting/Payroll APIs; 10MB max for Files API uploads
• Recommended Batching: Xero recommends batching up to 50 elements per request and keeping within typical monthly volumes of around 1,000 invoices/purchases for optimal performance
• High Volume Threshold: GET requests on high-volume endpoints may be further limited unless you apply Xero-specified optimized filters (subject to change)

Methods to prevent Xero rate limits

• Implement request batching and smart caching. Bundle multiple data requests into single API calls. Cache frequently accessed data locally. This reduces your total API consumption while maintaining data freshness.
• Use optimized filters and pagination. Apply Xero’s recommended filters to reduce payload sizes. Implement proper pagination to avoid large data dumps that consume multiple API calls unnecessarily.
• Switch to Coefficient for Excel or Google Sheets. Our platform handles rate limit management automatically. Smart sync protocols ensure your financial data stays current without hitting API constraints.

How to fix API rate limit exceeded?

Wait for the rate limit window to reset, implement request batching, or use a tool like Coefficient that manages rate limits automatically. Coefficient’s smart caching eliminates rate limit issues while keeping your data fresh.

Is the Xero API free?

Yes, Xero’s API is free to use within their rate limits. However, managing these limits effectively often requires additional tools or development resources. Coefficient provides a cost-effective solution that handles the complexity for you.

Quick answer

Xero webhooks provide real-time notifications when accounting data changes in your Xero organization. Setup requires registering an app in the Xero Developer Portal, configuring webhook subscriptions for specific events (invoices, contacts, etc.), and creating a publicly accessible HTTPS endpoint. 

Your endpoint must respond within 5 seconds with HTTP 200 OK and validate incoming requests using HMAC-SHA256 signature verification. Xero enforces rate limits of 5 concurrent calls, 60 calls per minute, and 5,000 calls per day. For no-code solutions, Coefficient offers instant webhook integration with Xero data in spreadsheets.

Prerequisites and requirements

Before setting up Xero webhooks, ensure you have the following foundational elements in place.

• Registered Xero app: Create an app in the Xero Developer Portal at developer.xero.com under “My Apps.” Your app must be connected to at least one Xero organization capable of generating webhook events.
• Webhook subscription configuration: Set up webhook subscriptions within the developer portal, specifying which event types your webhook should monitor. Options include contact changes, invoice updates, payment notifications, and other accounting events.
• Publicly accessible HTTPS endpoint: Xero requires SSL (port 443) for webhook delivery and won’t send notifications to localhost unless you use tunneling services like ngrok. Your endpoint must be reachable from Xero’s servers.
• Webhook signing key access: Obtain your webhook key from the developer portal. This key validates incoming requests from Xero by verifying the x-xero-signature header using HMAC-SHA256 encryption.
• Proper server response logic: Your endpoint must respond within 5 seconds with HTTP 200 OK for valid requests (no body or cookies). Invalid signatures must return HTTP 401 Unauthorized to maintain webhook functionality.

API limits and constraints

Xero enforces strict rate limits that directly impact webhook performance and integration reliability.

• Concurrent request limits: Maximum of 5 calls in progress simultaneously. Exceeding this limit triggers immediate rejections and 429 “Too Many Requests” errors.
• Per-minute restrictions: 60 calls per minute per connected organization, per app. Short-term bursts above this threshold receive 429 error responses and require retry logic implementation.
• Daily usage caps: 5,000 calls per day per organization, per app. This limit resets at midnight UTC and applies to all API interactions including webhook-triggered calls.
• Batch processing recommendations: Keep batch sizes to approximately 50 items for optimal performance. Larger batches may encounter processing delays or timeouts.
• High-volume considerations: Organizations using multiple Xero accounts face an overall minute limit of 10,000 calls across all accounts. Plan accordingly for multi-organization integrations.

Step-by-step Xero webhook setup

Follow this systematic approach to configure functional Xero webhooks for your integration.

Step 1: Create or select your Xero app

Navigate to the “My Apps” section in the Xero Developer portal and choose your existing app or create a new one for webhook functionality.

• Configure app settings: Ensure your app has appropriate scopes and permissions for the data you want to monitor. Webhook subscriptions require corresponding API access rights.
• Note your app credentials: Record your Client ID and Client Secret for authentication purposes. These credentials are essential for OAuth 2.0 flows and API access.
• Set up OAuth flows: Configure redirect URIs and authentication settings if your integration requires user consent for data access.

Step 2: Configure webhook subscription settings

Access your app settings and navigate to the “Webhooks” section to set up event monitoring.

Choose event categories: Select specific events you want to subscribe to, such as:

• Invoice creation, updates, or status changes
• Contact additions or modifications
• Payment notifications and bank transaction updates
• Purchase order changes
• Account and organization modifications

Enter endpoint URL: Provide your publicly accessible HTTPS endpoint URL where Xero will deliver webhook notifications. Ensure this URL can handle POST requests and process JSON payloads.

Configure retry settings: Xero automatically retries failed webhook deliveries. Understand the retry schedule to avoid processing duplicate events.

Step 3: Verify your endpoint with “Intent to Receive”

Xero sends a verification request to confirm your endpoint can properly handle webhook notifications.

Handle verification requests: Your endpoint must process the verification payload and respond appropriately:

javascript

Copy Code

// Example verification handler

app.post(‘/xero-webhook’, (req, res) => {

    const receivedSignature = req.headers[‘x-xero-signature’];

    const payload = JSON.stringify(req.body);

    const webhookKey = ‘YOUR_WEBHOOK_KEY_FROM_XERO’;

    

    // Generate HMAC signature

    const crypto = require(‘crypto’);

    const expectedSignature = crypto

        .createHmac(‘sha256’, webhookKey)

        .update(payload)

        .digest(‘base64’);

    

    // Verify signature

    if (receivedSignature === expectedSignature) {

        res.status(200).send(); // Valid signature

    } else {

        res.status(401).send(); // Invalid signature

    }

});

Respond within time limits: Ensure your endpoint responds within 5 seconds. Delayed responses cause verification failures and webhook disabling.

Process raw request body: Use the raw request body for signature verification, not parsed JSON. Many frameworks automatically parse JSON, breaking signature validation.

Step 4: Save configuration and obtain webhook key

After successful verification, save your webhook settings to activate event monitoring.

• Record webhook key: Xero generates a unique webhook key for your app. Store this key securely as it’s required for all future signature validations.
• Enable webhook subscriptions: Activate the specific event types you want to monitor. You can modify these subscriptions later as your integration needs evolve.
• Monitor webhook status: Use the developer portal to track webhook delivery success rates and identify any configuration issues.

Step 5: Test your webhook integration

Trigger test events in Xero to validate your webhook receives and processes notifications correctly.

• Create test events: Perform actions in your Xero organization that should trigger webhooks, such as creating invoices or adding contacts.
• Monitor delivery logs: Check your server logs and the Xero developer portal for webhook delivery confirmations and any error messages.
• Validate payload processing: Ensure your application correctly processes webhook payloads and performs the intended actions based on the received data.

Common integration issues

Real-world Xero webhook implementations encounter several recurring challenges that require careful attention.

“WebhookNotConfigured” errors and endpoint accessibility

• Incorrect URL configuration: Webhook URLs not properly set or publicly accessible due to firewall rules, DNS issues, or incorrect endpoint paths. Users notice changes in Xero don’t appear in their applications, causing data synchronization gaps.
• HTTPS protocol requirements: Servers unable to handle HTTPS traffic or respond using required secure protocols. According to developer documentation, Xero rejects HTTP endpoints and requires SSL encryption for all webhook deliveries.
• Connectivity validation failures: Common mistakes include typos in endpoint URLs, incorrect route handling, or firewalls blocking Xero’s webhook delivery servers. Tools like webhook.site or ngrok help identify connectivity issues during development.

Signature verification and “Intent to Receive” validation

• HMAC implementation complexity: Many developers struggle with Xero’s x-xero-signature header validation using HMAC-SHA256 encryption. Community discussions highlight confusion around base64 encoding, proper header comparison, and signature generation logic.
• Validation handshake failures: Incorrect status codes or response body content during the “Intent to Receive” process prevents Xero from enabling webhook delivery. Responses must be exactly HTTP 200 for valid signatures and HTTP 401 for invalid ones.
• Raw payload processing: Frameworks that automatically parse JSON break signature validation since HMAC calculation requires the raw request body. Developers must access unparsed request data for accurate signature verification.

Slow responses and retry loops during high server load

• Timeout cascade failures: Servers under high load that exceed Xero’s 5-second response requirement trigger retry loops. Stack Overflow discussions document cases where busy Apache servers delay webhook responses, creating cascading retry buildups.
• Retry storm amplification: Xero’s automatic retry logic can overwhelm already-stressed servers, creating exponentially increasing webhook queues that effectively break the integration until manually reset.
• Asynchronous processing solutions: Best practices include immediately logging and responding to webhooks, then processing payloads asynchronously. Switching from legacy server setups to lightweight Node.js or Go-based webhook receivers improves response times.

Hitting API and rate limits unexpectedly

• Downstream API call accumulation: Webhooks often trigger additional API calls to Xero or other systems, quickly exhausting the 60 calls per minute limit. Bulk updates or synchronized processes can breach daily limits unexpectedly.
• Rate limit monitoring gaps: Insufficient tracking of API usage leads to request failures and missed webhook events. Community recommendations stress monitoring x-rate-limit-remaining headers and implementing proactive alerts.
• Cascading failure prevention: Implement exponential backoff retry logic, queue management systems, and rate limit tracking to prevent webhook-triggered API calls from overwhelming Xero’s limits and breaking data synchronization.

Frequently asked questions

Does Xero support webhooks?

Yes, Xero provides comprehensive webhook functionality through the Xero Developer Portal. You can subscribe to various events including invoice changes, contact updates, and payment notifications. However, setup requires technical implementation including HMAC signature validation and proper endpoint configuration.

How do I set up Xero webhooks?

Create an app in the Xero Developer Portal, configure webhook subscriptions for desired events, and provide a secure HTTPS endpoint URL. Your endpoint must validate HMAC-SHA256 signatures and respond within 5 seconds. Complete the “Intent to Receive” verification process to activate webhook delivery.

What are Xero webhook rate limits?

Xero enforces 5 concurrent calls, 60 calls per minute, and 5,000 calls per day per organization. Exceeding these limits results in 429 “Too Many Requests” errors. Monitor your API usage carefully, especially when webhooks trigger additional API calls to Xero or other systems.

How do I validate Xero webhook signatures?

Use HMAC-SHA256 encryption with your webhook key to generate a signature from the raw request body. Compare this with the x-xero-signature header value. Return HTTP 200 for matching signatures and HTTP 401 for invalid ones. Signature validation is required for webhook functionality.

Can I use Xero webhooks without coding?

While Xero webhooks require technical implementation, Coefficient provides a no-code solution for real-time Xero data integration with spreadsheets. This eliminates the need for custom webhook development, signature validation, and server maintenance while providing the same real-time data benefits.

Quick Answer

Setting up Xero API integration requires registering an OAuth app in the Xero Developer Portal, implementing proper authentication flows, and managing strict rate limits (60 calls/minute, 5,000/day). The process involves configuring redirect URIs, handling chart of accounts mapping, and building robust error handling for API quotas and token management.

While custom development provides comprehensive control over accounting workflows, it demands significant expertise in OAuth protocols, data mapping complexities, and ongoing maintenance as Xero’s platform evolves. Coefficient for Excel and Coefficient for Google Sheets eliminate this complexity entirely, providing instant Xero connectivity to spreadsheets in minutes without rate limiting concerns, authentication headaches, or data mapping challenges.

Prerequisites and Requirements

Before you begin:

• Xero Account: Active Xero account (use free trial or demo company for testing)
• Developer App Registration: Register app in Xero Developer Portal to generate Client ID and Client Secret
• Redirect URI: Set exact redirect URI for OAuth flow (e.g., http://localhost:3000/callback)
• Programming Experience: Backend development knowledge and OAuth flow understanding
• SDK Selection: SDKs available for Node.js, Python, Java, PHP, Ruby, C#
• OAuth Scopes: Choose appropriate API scopes for use case (e.g., accounting.transactions)
• Sandbox Environment: Use Xero demo company for testing without affecting real data

API Limits:

• Per Minute: 60 API calls per minute per organization/app
• Per Day: 5,000 API calls per day per organization/app
• Concurrent Requests: Maximum 5 at any time per tenant
• Bulk/Paging: Up to 1,000 results per page (as of 2025)
• High Volume Endpoints: Elevated limits for endpoints like GET /invoices
• Rate Limit Headers: Track x-rate-limit headers for monitoring
• Best Practices: Implement exponential backoff, use webhooks to reduce polling, cache static data, batch requests efficiently, proactive token refresh

Step-by-Step Xero API Integration Setup

Step 1: Create Your Developer Account and App

Start with the basics. Sign up for a free Xero account and enable the demo company for safe testing.

Navigate to the Xero Developer Portal and create your OAuth 2.0 application. This generates your Client ID and Client Secret—store these securely.

Choose your OAuth scopes carefully. Request only necessary permissions to reduce friction during user authorization.

Step 2: Configure Authentication Flow

Set your redirect URI precisely. Even small mismatches will break OAuth authentication entirely.

For local development, use something like http://localhost:3000/callback. For production, ensure HTTPS and exact URL matching.

Implement the complete OAuth flow:

1. Redirect users to Xero’s authorization endpoint
2. Handle the callback with authorization code
3. Exchange code for access and refresh tokens
4. Store tokens securely with proper encryption

Step 3: Handle Chart of Accounts Mapping

This step separates amateur from professional integrations. Don’t assume default accounts exist—users customize their chart of accounts extensively.

After successful authentication, immediately fetch the user’s chart of accounts using the /accounts endpoint. Build dropdown controls populated with actual account data, never text fields.

Best practices for account mapping:

• Set intelligent defaults (look for “Sales” accounts for revenue mapping)
• Filter by appropriate account types for each use case
• Offer to create new accounts when relevant ones don’t exist
• Validate mappings before each data export

Step 4: Implement Data Synchronization Logic

Choose between one-way or bidirectional sync based on your use case. One-way is simpler but limits functionality.

For bidirectional sync, establish foreign key relationships by storing Xero’s ContactID in your system or setting ContactNumber with your unique identifier.

Handle contact synchronization carefully:

• Match existing contacts by name or email to prevent duplicates
• Prompt users to map or create new contacts when conflicts arise
• Use “If-modified-since” headers to sync only changed records

Step 5: Build Rate Limiting and Error Handling

Rate limits will break your integration without proper handling. Monitor x-rate-limit headers religiously and implement exponential backoff for 429 errors.

Copy Code

const delay = (ms) => new Promise(resolve => setTimeout(resolve, ms));

 

async function makeXeroRequest(url, options, retries = 3) {

    for (let i = 0; i < retries; i++) {

        try {

            const response = await fetch(url, options);

            

            if (response.status === 429) {

                const retryAfter = response.headers.get(‘Retry-After’) || Math.pow(2, i);

                await delay(retryAfter * 1000);

                continue;

            }

            

            return response;

        } catch (error) {

            if (i === retries – 1) throw error;

            await delay(Math.pow(2, i) * 1000);

        }

    }

}

Use webhooks instead of constant polling to stay within API limits while maintaining real-time sync.

Step 6: Test Across Different Scenarios

Validate thoroughly before production:

• Different Xero organization setups and custom configurations
• Various user permission levels and access restrictions
• High-volume data scenarios approaching rate limits
• Token expiration and refresh cycles
• Network failures and retry scenarios
• Multi-currency and tax rate configurations

Reference: Xero Developer Integration Best Practices

Common Xero API Integration Issues

One-way vs Two-way Synchronization

Most commercial integrations only support one-way sync, creating significant operational friction. Data flows from Xero to external systems or vice versa, but never both directions automatically. This forces manual workarounds, custom scripts, and delayed data updates.

Real-world impact: Finance teams lose visibility when invoice updates in Xero don’t reflect in CRM systems. Sales teams create opportunities that never sync back to accounting. Users resort to building custom middleware or maintaining duplicate data entry processes.

Reddit users consistently report dealing with “manual” sync processes even with premium integration tools. The lack of robust bidirectional data flows creates visibility gaps across business platforms, especially for project-level financial data and deal associations.

Workaround complexity: Teams build custom scripts, use multiple middleware tools, or accept data inconsistency as “normal.” The rare integrations offering two-way sync often fail on edge cases or custom objects.

Rate Limiting and Throttling

API rate limits cause widespread integration failures. The 60 calls per minute and 5,000 daily limits seem generous until you hit them during batch operations or automated workflows.

Sync failures multiply quickly. Each invoice sync might require multiple API calls for line items, contacts, and tax rates. Hitting limits blocks all further operations until the quota resets, creating cascading delays in business processes.

Reddit developers emphasize that rate limiting errors are the most prevalent issue, especially during month-end processing when multiple systems attempt bulk operations simultaneously. Missing or failed syncs have real consequences for financial reporting and compliance.

Required mitigation: Implement comprehensive retry logic, monitor rate limit headers continuously, and design systems that gracefully handle quota exhaustion. Many developers underestimate the complexity required for production-grade rate limit handling.

Authentication and Token Management

OAuth complexity frustrates even experienced developers. Mismatched redirect URIs, expired access tokens, missing offline_access scopes, and improper secret handling create constant authentication failures.

Developer estimates suggest over 30% of API failures relate to credential or token management issues. The secure-by-design OAuth flow becomes a significant implementation hurdle without deep authentication expertise.

Common failure points:

• Redirect URI mismatches breaking the entire OAuth flow
• Access tokens expiring without proper refresh logic
• Missing or incorrect scopes preventing API access
• Insecure token storage compromising integrations

Stack Overflow and Reddit threads document extensive troubleshooting around these authentication challenges, with recommendations for proactive refresh logic and precise environment configuration.

Data Mapping and Complex Workflows

Xero’s flexible data model creates mapping nightmares. Chart of accounts variations, custom tax codes, multi-currency transactions, and project associations don’t map cleanly between systems without extensive customization.

Integration breaking points:

• Mismatched tax codes causing accounting errors
• Unsupported multi-currency transactions failing silently
• Contact/invoice syncing to incorrect projects or deals
• Custom fields and objects not transferring between systems

Workflow brittleness: Commercial connectors often fail on edge cases that work fine in demonstrations. Users describe using multiple middleware tools simultaneously to handle what should be standard accounting integrations.

Reddit threads document ongoing complaints about data mapping reliability, forcing teams to build custom scripts or accept incomplete synchronization as normal business operations.
