Bad Request (BAD_REQUEST)

The request was invalid. The response body typically contains specific error details explaining what went wrong.

Common causes

Malformed JSON body - The request body contains invalid JSON, such as missing commas, unclosed brackets, or trailing commas.
Missing required fields - The request is missing one or more fields that the API expects.
Invalid Content-Type header - The Content-Type header does not match the format of the request body. For example, sending JSON without setting Content-Type: application/json.
Invalid parameter types - A field value does not match the expected type, such as sending a string where a number is required.

Check the response body for specific error messages. Zuplo returns detailed error information that identifies the exact issue.
Validate the request body using a JSON linter or validator before sending.
Verify that all required headers are present and correctly formatted.
Compare the request against the API documentation to ensure all required fields are included with the correct types.

Use a tool like curl -v or an API client such as Postman to inspect the full request and response, including headers and body.

If the request body fails JSON Schema validation, see Schema Validation Failed for more details.
