Status and Errors Codes

Meltwater uses conventional HTTP response codes to indicate the success or failure of an API request. In general, codes in the 200 range indicate success. Codes in the 400 range indicate an error that failed given the information provided (for example, a required parameter was omitted). Codes in the 500 range indicate an error with Meltwater's servers. Status codes returned by the API:
200 OK Your request was successful.
400 Bad request There is an issue with your request. Check you are providing all required parameters.
401 Unauthorized Check you are providing the correct authentication header and API key.
403 Forbidden You are not authorized to access the endpoint.
409 Conflict The change you're making conflicts with a resource or query that already exists
