API Error Reference
Error handling, without invented contracts
Use the live OpenAPI contract and the API response itself for endpoint-specific validation and error handling.
Merion does not publish a separate list of named error codes because validation and permissions depend on the endpoint and caller role. Start with the live OpenAPI contract, inspect the returned error and field details, and include the response X-Request-ID when contacting support.

Build resilient error handling
Recipes show the how; concepts explain the why.
