validation_failed

HTTP status: 422 Unprocessable Entity. Retrying the same request unchanged fails the same way.

Why it happens

• A field has the wrong type, such as a number where a string is expected.
• A value breaks a limit, such as an order_id longer than 255 characters or expires_in outside 900 to 86,400 seconds.

What to do

Fix the fields listed in errors; each has a JSON pointer, a code and a detail.

Example

The response is application/problem+json. Branch on code, never on title or detail. See errors for the format.
