API documentation
The reference guide for an application's API endpoints, authentication methods, request formats, response schemas, and rate limits. Quality API docs are the single biggest factor in how fast PURIST can build an integration.
Expert insight
API documentation is frequently out of sync with the actual API behavior, especially for fields marked optional that are, in practice, always present, or vice versa. Testing against the real API response rather than trusting the documented schema catches these gaps before they cause a production failure.
In a real workflow
Before building a Pipedrive integration, the developer checks the documentation for field keys, pagination and rate limits.
Common mistakes
- Relying on old blog posts instead of the current documentation.
- Not documenting your own internal endpoints for the next person.
