BAD_REQUEST

Property	Value
HTTP status	400 Bad Request
Retryable	Yes
Error code	BAD_REQUEST

Summary

The server could not understand the request because of malformed syntax, missing required headers, or an otherwise invalid request structure.

When it occurs

• The request body is not valid JSON or is missing entirely when one is required.
• A required query parameter or header is absent.
• The Content-Type header does not match the expected media type.
• The request structure is syntactically valid but semantically nonsensical (e.g., contradictory parameters).

How to fix

• Ensure the request body is valid JSON and matches the expected schema.
• Check that all required headers (e.g., Content-Type: application/json) are present.
• Review the API specification for the endpoint to confirm required parameters and their formats.
