Proxy Public Beta is not available to new customers

Proxy Public Beta is currently closed for new customers. Please consider using Twilio Conversations and Programmable Voice directly if you are building your masking application.

Note that this does not have any impact on Twilio Flex customers.

(warning)

Public Beta for customers already using Proxy

Twilio's Proxy API is currently available as a Public Beta product. Some features are not yet implemented and others may be changed before the product is declared as Generally Available.

Public Beta products are not covered by a Twilio SLA.

We can send text messages through the Proxy API by creating a Message Interaction on a Participant. The referenced Participant will receive the message from their allocated proxy number on the appropriate channel.

Note: Only POST (create) is available on Message Interactions. To query past messages you've created with this resource, query the Interaction resource.
