Backlog update: We’re discontinuing the following APIs

As part of our routine housekeeping to keep Backlog running smoothly for you, we’re clearing out a few APIs that we’ve seen a significant drop in access. This is all part of our effort to keep Backlog fresh, efficient, and ready to support you with the tools that matter most.

Key dates to remember

The following APIs will be removed after August 28, 2025. If you’re still using any of them, now’s the time to transition to the new alternatives listed in the API documentation.

Impact on API client libraries

With the removal of these APIs, we’ll also be discontinuing support for our API client libraries Backlog4j and backlog-js. These libraries will no longer be available after the APIs are deleted.

How to know If you’re affected

If you have used any of the deprecated APIs within the last three months, you will receive an email notification starting today, August 28, 2024. This notification will include details on which APIs you’ve been using and how to transition to the new URLs.

Important note for iOS app users

iOS apps running versions earlier than 2.20.5 will no longer work after the APIs are removed. Please update to the latest version to ensure continued service without interruptions.
