Messaging Service PhoneNumber Resource

(warning)

Public Beta

The Service Resource is currently available as a Public Beta product. This means that some features for configuring your Messaging Service via the REST API are not yet implemented, and others may be changed before the product is declared Generally Available. Messaging Service Configuration through the Twilio Console(link takes you to an external page) is Generally Available.

Public Beta products are not covered by a Twilio SLA(link takes you to an external page).

The resources for sending Messages with a Messaging Service are Generally Available.

The PhoneNumber subresource of a Service instance represents a phone number you have associated to the Service.

When sending a message with your Messaging Service, Twilio will select a phone number from the service for delivery.

Inbound messages received on any phone number associated to a Messaging Service are passed to the inbound request URL of the Service with the TwiML parameters that describe the message.
