API integration platforms help businesses run their operations cohesively.

And because these platforms allow companies to communicate information across various programs and pull up data from them, the users can operate without having to log in to multiple software every.single.time.

They just need to access the API integration platform to manage and communicate with their tech stack.

However, not all API integration tools are created equal.

You need a platform that helps you integrate all APIs across various applications at scale while also addressing your company’s needs.

Essentially, your best bet is to opt for an API integration platform that can streamline your company’s connection among multiple APIs.

If you’re not sure where to start, we’re here to help.

This guide covers the top API integration platforms, including their features and the costs of investing in these tools.

What is API integration?

Application Programming Interface (API) facilitates connectivity and communication between multiple software applications.

In simple terms, an API acts as a messenger that processes requests necessary for enterprise systems to function.

API makes it possible for your business-critical data pipelines, devices, and applications to connect and interact.

API integration refers to this seamless connectivity and interaction. It allows you to automate your business processes and enhance the sharing and embedding of data among various systems and apps.

For instance, API allows the syncing of leads between marketing automation systems with your Customer Relationship Management (CRM) system. This results in streamlined data flows that help your sales team work more efficiently.

API integration works by connecting two (or more) applications to perform a joint function through their APIs. This involves using the API layer of the applications to allow them to “talk” to each other.  

For instance, the Marketo to Salesforce integration combines API integration between the two platforms.

The sync is bidirectional (only for contacts, leads, and Salesforce campaigns), which means that changes you make in either Marketo or Salesforce will reflect the updates on both systems.

Why do you need API integration platforms?

If you’re still on the fence about the importance of API integration platforms for your business, these reasons might help you decide.

API integration tools allow you to:

  • Connect multiple systems easily. API integration platforms simplify the connection of your multiple systems using their APIs. This helps you manage all APIs collectively while enjoying the shared benefits of each system across various apps.

Plus, it’s easier to manage an integration platform than to handle a group of APIs individually.

  • Access and secure data. Modern API integration software provides seamless access to your required data from other systems with little to no risks of data loss or bugs exchange.

The platforms often come with robust infrastructure to keep your data intact while accommodating your data security needs.

  • Boost your productivity. API integration tools allow your development team to focus on more critical tasks since the platforms can free them from building, managing, or fixing API integrations.

  • Be more cost-effective. Creating multiple individual integrations can cost your business a fortune, including time and other resources.

API integration platforms provide a more cost-effective solution since you won’t need to spend thousands of dollars developing multiple ones.

Top 5 API integration platforms

Choosing the best-fitting API integration software requires knowledge of your business needs and research for which tool best addresses those requirements.

Start by assessing these top API integration platforms.

1. Coefficient

An API integration platform that works well with Google Sheets and one of the best tools available right now is Coefficient.

Coefficient provides the easiest and fastest way to integrate your APIs and data sources with Google Sheets with minimal to no coding.

This API integration tool allows you to instantly import data from any database, file, or SaaS system and filter and sort your data before syncing to your spreadsheet.

You can configure your data to auto-update on your preferred schedule. This way, you won’t need to manually import and sync every time new data comes in, saving you valuable work hours and resources.

Essentially, Coefficient’s API integration allows you to set up your data flows once, and the app automates the rest for you.

Install the Coefficient Salesforce, HubSpot Data Connector as a Google Sheets add-on and choose your data source (or sources). Then, customize the data you want to pull up and import everything to your spreadsheet with one click (and within a few seconds or minutes).

Coefficient supports systems and apps, such as Salesforce, HubSpot, Jira, MySQL, Looker, Google Analytics, and more.


  • Pull volumes of live data from your systems to Google Sheets without coding  
  • Refresh data automatically on any schedule
  • Set automated data updates through email and native Slack alerts
  • Connect systems and sync data with one click

  • Coefficient isn’t free but the benefits of investing in the tool for your business can far outweigh the costs.  


Coefficient offers Starter, Pro, and Enterprise pricing tiers, starting at $49/month (billed annually). You can try Coefficient for free, but this has limited features.  

2. Zapier

Zapier provides easy-to-use basic API integration functionalities.

The platform is an excellent API integration platform for beginners and non-tech-savvy teams. It offers a clickable, visual interface with more than 3,000 app integrations to help your teams automate workflows between cloud and web-based services.  

Zapier’s API integration works by setting up workflows called Zaps that don’t require any kind of coding.

You can choose from the available apps you want to integrate, such as Google Sheets, Slack, MailChimp, and other systems (from Business Intelligence (BI) to sales and CRM).

For instance, you can set up a Zap that automatically adds your new Facebook Lead Ad leads to your Mailchimp list.

Configure your workflow using the point-and-click integration features and choose your triggers and actions.

Zapier automates the actions and data flows between the two apps, eliminating a chunk of busywork for your teams.  

Still, Zapier can be a user-friendly API integration tool to empower your non-developer team members.

  • Limited by the recipes that are provided


Zapier offers a free-forever account, but you can only automate 100 tasks per month. This includes five single-step Zaps and a 15-minute update time.

With the Starter plan, you can get more features at $29.99/month ($19.00 annual billing).

The Google spreadsheet API integration offers uses in many industries, including finance, marketing, app development, and data analytics.  

You’ll get all the tools you need from Google Sheets to seamlessly analyze, visualize, and uncover insights from your data.

Here’s part of the Go command-line code.

If you choose the no-code option, you can select from the many platforms offering code-free API integrations that work well with Google Sheets.
