Upcoming API deprecation for the phones.testers resource
Effective date: January 31, 2026
Currently, you may be using the legacy phones.testers resource, which is limited to sending an invite and viewing the status for a single test device.
To provide more comprehensive control, we recently launched the new testers API for complete tester lifecycle management. Now you can send/resend invites, get status, and remove testers programmatically.
Because of this expanded functionality, we are deprecating the legacy phones.testers resource. This resource will be permanently removed on January 31, 2026.
To ensure uninterrupted testing for your agents, all partners are required to migrate their implementations to the new, streamlined testers API resource before January 31, 2026. Agents that haven't migrated won't be able to invite or manage test devices after this date.
| Resource | Status | Deprecation deadline |
|---|---|---|
| phones.testers | Deprecated | January 31, 2026 |
| testers | Current | Migration required before January 31, 2026 |
What you need to do:
- Review the new testers API reference and the updated guide to set up a test device.
- Update your existing code that calls the
phones.testers.createmethod to use the newtestersresource endpoints. - Implement and test the new logic before January 31, 2026.
We strongly encourage you to begin migrating as soon as possible to benefit from the new programmatic testing features.
