API Errors
The Postman v2 API 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 a request that failed given the information provided (e.g., a required parameter was omitted, not having access to the campaign due to wrong API key, etc.). Codes in the 5xx range indicate an error with Postman’s servers (these will be rare).
Some 4xx errors that could be handled programmatically include an error code that briefly explains the error reported.
