Upcoming enforcement of regional endpoints for batch capability checks

Effective date: Q2 2026

Starting in the second quarter of 2026, the users.batchGet method will require the use of regional endpoints. From then on, batch requests must be sent to the API endpoint that corresponds to the geographical region of the phone numbers in that batch.

Why we're making this change:

To optimize API performance and reliability, and to contain the impact of any potential disruptions.

What you need to do:

  1. Update your application to call the correct regional endpoint for your users.batchGet requests.

  2. Ensure each users.batchGet request contains phone numbers from a single region only. Requests containing mixed-region phone numbers or sent to the incorrect regional endpoint will fail with a 400 Bad Request error.

What's not changing:

Single capability checks (phones.getCapabilities) and sending messages are not affected by this enforcement at this time. However, we strongly recommend using regionalized APIs for all calls to optimize API performance now and to prepare for future updates.

Upcoming API deprecation for the phones.testers resource

Effective date: February 28, 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 February 28, 2026.

To ensure uninterrupted testing for your agents, all partners are required to migrate their implementations to the new, streamlined testers API resource before February 28, 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 February 28, 2026
testers Current Migration required before February 28, 2026

What you need to do:

  1. Review the new testers API reference and the updated guide to set up a test device.
  2. Update your existing code that calls the phones.testers.create method to use the new testers resource endpoints.
  3. Implement and test the new logic before February 28, 2026.

We strongly encourage you to begin migrating as soon as possible to benefit from the new programmatic testing features.
