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:
Update your application to call the correct regional endpoint for your
users.batchGetrequests.Ensure each
users.batchGetrequest contains phone numbers from a single region only. Requests containing mixed-region phone numbers or sent to the incorrect regional endpoint will fail with a400 Bad Requesterror.
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.
