API change management

Automatic API changelog

Bump automatically builds a changelog for your API. Each time you upload a new version of your API definition, you will have a new event in your changelog. A link to the changelog page is available on each documentation:

The changelog link

As you can see below on the Bump API changelog, every changes we made are listed: whether it's a structural change (endpoint or parameter removed, modified or added for example) or a content change (description or example modification).

Breaking changes identification

Bump automatically identifies when a change is breaking for your API consumers. Here are the changes considered as breaking:

  • Rename or delete endpoint, unless it was deprecated before
  • Rename or delete a property (body, header or query parameter), unless it was deprecated before
  • Modify the type of a property
  • Set an existing property as required
  • Add or delete a security requirement

Changes notification

Bump can notify changes via Slack, email, RSS or any custom HTTP webhook.


Each time your API changes, you can notify your team directly on Slack by activating the Slack integration in your API integrations settings:

Check the "Notify changes on Slack", fill your webhook URL and the channels you want to get the notifications on


Users can subscribe to your API changelog and receive a weekly digest.

Email changelog subscription


The changelog page exposes an RSS feed your users can subscribe to. Here is an example with the Bump API changelog.


You can define as many webhooks as you wish to receive structural changes when they occur on your documentations. Please check the dedicated page to find out how to setup a webhook.

GitHub integration

With our Github Action, you can receive automatic API diff comments directly in your pull requests. This pull request comment will include:

  • a diff summary
  • information about the breaking change state
  • a link to a visual diff page
