Removal of UAT API Legacy Domain

The UAT API legacy domain single-api-uat.core.aws.sevensenders.com will be completely removed on March 16, 2026.

What's Changing

The UAT API domain single-api-uat.core.aws.sevensenders.com is being removed. Going forward, the only supported UAT API domain is:

api-uat.sevensenders.com

Why This Change

As part of ongoing infrastructure improvements, we are consolidating our API endpoints under a single, properly maintained domain. The updated domain ensures reliable routing and full access to all current and future API features. Continued use of the legacy domain may result in loss of access to some features over time.

Action Required

If you are using single-api-uat.core.aws.sevensenders.com in your API calls, please update your configuration to use api-uat.sevensenders.com before March 16, 2026. After this date, the old domain will no longer be available.

Timeline

• Today (February 11, 2026): Removal notice issued
• March 16, 2026: single-api-uat.core.aws.sevensenders.com will be completely removed
