Service Rate Limits

Service Rate Limits makes it easy to use Twilio's battle-tested rate-limiting services to protect your Verify deployment. With Service Rate Limits, you can define the keys to meter and limits to enforce when starting user verifications. Together with Verify's built-in platform protections Service Rate Limits gives you turnkey protection with flexibility.

Prerequisites:

  1. Create a Verification Service
