Authentication

Authentication to the API is performed via HTTP Basic Auth. Provide your API key as the basic auth username value. You do not need to provide a password. If you need to authenticate via bearer auth (e.g., for a cross-origin request), use -H "Authorization: Bearer yourapikey" instead of -u yourapikey. All API requests must be made over HTTPS. Calls made over plain HTTP will fail. API requests without authentication will also fail. 
curl https://api.mergent.co/v2 \
  -u yourapikey:
  # The colon prevents curl from asking for a password.

Errors

Mergent uses conventional HTTP response codes to indicate the success or failure of an API request. In general:
  • Codes in the 2xx range indicate success.
  • Codes in the 4xx range indicate an error that failed given the information provided (e.g., a required parameter was omitted, etc.).
  • Codes in the 5xx range indicate an error with Mergent’s servers.
