This feature is currently in the GA maturity stage.
Customers using the below products will now have access to the Global Safe List API.
Note : Global Safe List API currently only supports the SMS channel.
Global Safe List API allows you to maintain a list of phone numbers that will never be blocked by Verify Fraud Guard, Verify Geo Permissions, Programmable Messaging SMS Pumping Protection or any other internal fraud & risk check solution.
While we are always adapting our fraud detection systems to keep false positives extremely low, Global Safe List API adds another layer of protection by letting you mark legitimate phone numbers as safe to ensure they are never erroneously blocked.
This API contains three endpoints:
Alternatively, you can add a previously blocked phone number to the Global Safe List via Twilio Console on the Verify Logs Blocked Verifications tab. See Viewing Logs With Twilio Console for more information.
Global Safe List API provides a built-in rate limit of 500 requests per minute. If you reach this limit, you will start receiving HTTP 429 "Too Many Requests" responses.
Global Safe List API has a timeout value of 15 seconds. However, its 99th percentile is within 1 second.
These properties are returned in the JSON response output.
