Authy Return and Error Codes



As of November 2022, Twilio no longer provides support for Authy SMS/Voice-only customers. Customers who were also using Authy TOTP or Push prior to March 1, 2023 are still supported. The Authy API is now closed to new customers and will be fully deprecated in the future.

For new development, we encourage you to use the Verify v2 API.

Existing customers will not be impacted at this time until Authy API has reached End of Life. For more information about migration, see Migrating from Authy to Verify for SMS(link takes you to an external page).

As a RESTful API, Twilio's Authy API will return HTTP responses and error codes which will help verify normal behavior as well as contextualize exceptions.

Return Codes

return-codes page anchor

The following status codes are used:

200: OK Response is correct. The body of the response will include the data requested.

400: Bad Request There was an error with the request. The body of the response will have more info.

401: Unauthorized Token is invalid. If your API key is wrong a 401 will be generated. Please check the API key.

429: Too Many Requests API usage limit. If you reach API usage limits, a 429 will be returned. Please wait until you pass the limit and attempt the call again.

503: Service Unavailable There are multiple possible reasons for a HTTP 503 error.

  • Internal Twilio error.
  • Your application is accessing an API call you don't have access to.

When the API returns a status other than 200, we add an error code in the message body. This table enumerates and describes all of the possible error codes.
