The editor automatically applies the correct schema based on your script type. If your script appears to be the wrong type, the editor will flag it and offer a one-click option to switch, making it easier to catch mismatches before they cause issues in production.
This is available on the new dashboard only.
You can now pass custom SIP headers when creating outbound calls through the REST API, giving you greater control over SIP-level metadata for routing, tracing, and downstream system integration. This brings the REST API in line with the existing connect.headers support already available in SWML. Full documentation coming soon.

Configure routing, conditional logic, and replies directly in SWML. This goes well beyond basic auto-reply, supporting inline switching on message content, variable expansion, HTTP requests, and multi-section documents with full control flow.
To get started, navigate to Phone Numbers in the dashboard, select a number, and assign a SWML Script or Webhook under Inbound Message Settings. You can also assign handlers via the REST API.
This is available on the new dashboard and REST API. If you're on the legacy dashboard, reach out to Support or Sales to get access.
A previously misclassified MMS error code has been corrected. Certain MMS delivery failures that were reported as unknown_destination_handset / 30005 will now appear as mms_expired_rejected_failed_or_unsupported / 30011, more accurately reflecting the type of failure that occurred.
Spaces with large numbers of AI Agents sometimes experienced errors and timeouts when loading the AI Agents list. This has been resolved and the page now loads quickly regardless of how many agents are configured.

The documentation covers three key areas:
Send a Message: Create and queue outbound SMS or MMS messages. The API automatically determines message type based on the presence of media or the send_as_mms flag. Supports status callbacks, so your system can receive real-time delivery updates.
Redact a Message: Clear the body of a previously sent message for compliance or privacy purposes. Works on messages in terminal states (delivered, undelivered, or failed).
Message Status Callback: Receive a webhook payload each time a message transitions to a new delivery state. The same payload shape is used across the REST API, Relay SDK, and SWML send_sms callbacks, keeping your integration consistent regardless of how you send messages.

Message logs now display error codes and error messages directly in the UI, giving you full visibility into failed messages without needing to make a separate API call.
Previously, this information was only accessible via the API. Now, if either value is present, you can see it at a glance in the dashboard — making it faster to diagnose delivery issues without needing to make a separate API call.
The Resources UI filter for Scripts has been separated into two distinct filters: SWML and CXML.
This makes it easier to find and manage your scripts by type without sorting through a combined list.
You can now pass codecs as either an array of strings or a comma-separated string when making a calling/calls dial request, giving you greater flexibility in how you configure your calls.
Supported codecs include: PCMU, PCMA, OPUS, G729, G722, VP8, and H264.
📖 See the full codecs parameter documentation for details.

The code editor toolbar has been enhanced for easier script management.
You can now copy scripts directly from the toolbar, and read-only editors still provide access to tools like copy and resize.
You can now test resources directly from the browser.
A new Click to Test button on the Resource detail screen lets you initiate a test call without assigning a handler or using an external phone.
