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.

HTTP status code summary

Status code
What it means

200 - OK

Everything worked as expected - you will get this status code for successful GET requests.

201 - Created

Everything worked as expected - your message(s) is/are created in our system. You will get this status code for successful POST requests that lead to the creation of messages.

400 - Bad Request

The request was unacceptable, often due to missing a required parameter.

401 - Unauthorized

No valid API key provided.

403 - Forbidden

The API key doesn't have permissions to perform the request. If you receive a HTTP response code 403 and error code 1010, please contact us here.

404 - Not Found

The requested resource doesn't exist.

429 - Too Many Requests

Too many requests hit the API too quickly. We recommend an exponential backoff of your requests.

500, 502, 503, 504 - Server Errors

Something went wrong on Postman’s end. (These will be rare.)
