Verify v1 API has reached End of Sale. It 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. v2 has an improved developer experience and new features, including:
Existing customers will not be impacted at this time until Verify v1 API has reached End of Life. For more information about migration, see Migrating from 1.x to 2.x.
As a RESTful API, Twilio's Verify API will return HTTP responses and error codes which will help verify normal behavior as well as contextualize exceptions.
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.
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.
