ERR_003 – Invalid API Request Parameters

The API call you just made contains one or more parameters that are malformed, missing, or contain invalid values. This prevents the server from processing the request.

Common Causes

• Missing required query parameter.
• Parameter type mismatch (e.g., sending a string where an integer is expected).
• Value out of allowed range or not following the required format.
• Using deprecated parameter names.

How to Resolve

1. Review the API parameter documentation for the endpoint you are calling.
2. Ensure all required parameters are present and correctly spelled.
3. Validate the data types and formats of each parameter before sending the request.
4. Use our Parameter Validator tool to test your request payload.
