invalid_request

HTTP 400, application/problem+json. When: malformed body, missing field, bad parameter, callback_url not a string.

What to do

The request itself is malformed: the body is not a JSON object, a field is missing or has the wrong type, a header such as Idempotency-Key is invalid, or callback_url is not a string. detail says what is wrong. Fix the request; retrying it unchanged gives the same error.

See all codes on Errors. Include the request_id when you contact support.
