Sender IDs
Branded identifiers that appear as the sender of verification messages. Submit new sender IDs for approval and list the ones currently registered on your account.
Phone number lists
Allow list entries bypass anti-fraud checks; block list entries reject verifications. Use these endpoints to script bulk updates or sync lists from your own fraud tooling.
Access to the Management API is opt-in. Contact our support team to enable it on your account.
