set_swml_webhook

Route inbound calls on this phone number to an SWML webhook URL. Your backend returns an SWML document per call. The server auto-creates a swml_webhook Fabric resource keyed off this URL.

This is a typed wrapper over update that sets call_handler to relay_script and populates call_relay_script_url for you.

Parameters

resource_id

strRequired

ID of the phone number to bind.

url

strRequired

Webhook URL that returns SWML. The server keys the auto-created Fabric resource off this value.

**extra

Any

Additional fields forwarded to update (e.g. name, call_fallback_url).

Returns

dict — The updated phone number resource.

    host="your-space.signalwire.com",
