Looker delivers modern business intelligence and data platform solutions for enterprise analytics and reporting. Explore essential information for building Looker API integrations and webhooks.
Limitations to Looker API
- Instance-specific endpoints complicate multi-tenant integrations. Each Looker instance has its own API endpoint, making it challenging to build scalable solutions across multiple customer environments.
- LookML knowledge required for advanced queries. While the API provides access to data, creating complex queries or custom dimensions often requires understanding Looker’s proprietary modeling language.
- Rate limits based on query complexity, not just volume. The 500,000 query-based calls per month can be consumed quickly with complex dashboard refreshes or large dataset operations.
- Limited sandbox options increase development costs. Only time-limited sandboxes are available for free, requiring paid instances for extended development and testing.
