DataGrail uses the following endpoints to authorize and test the connection:

Method	Endpoint	Purpose	Docs
GET	/accounts	Validate credentials
POST	/oauth2/token	Get and refresh access token

---

Limits

Limits in Coupa are calculated using the leaky bucket algorithm. All requests that are made after rate limits have been exceeded are throttled and an HTTP 429 Too Many Requests error is returned. Requests succeed again after enough requests have emptied out of the bucket.

• DataGrail supports requests throttling to stay within 70-80% of specified service rate limits.
• DataGrail processes API responses with HTTP 429 status to interrupt requests, waiting and retrying (using an exponential backoff strategy).
