Assign domain application handler

View as MarkdownOpen in Claude

Assigns an existing resource as the calling handler for a SIP Domain Application, so inbound SIP calls to that Domain Application run the resource. Use it when the Domain Application already exists and its handler should be a Fabric resource such as an AI Agent, Call Flow, or SIP Gateway. Use Create domain application to create and configure the SIP-facing Domain Application itself.

Currently only supports calling as a handler and automatically defaults to it.

Permissions

The API token used to authenticate must have the following scope(s) enabled to make a successful request: Voice, Messaging, Fax, or Video.

Authentication

AuthorizationBasic

SignalWire Basic Authentication using Project ID and API Token.

Example:

Authorization: Basic base64(project_id:token)
