Hi there,

We've noticed that an API tester token associated with your account on xxx.slack.com has not been used in a while. You may have generated this token to simply test our API methods or used it in an app to access your workspace and automate a workflow.

API tester tokens are quite powerful and it is a best practice to revoke them if they are not being used. We have gone ahead and revoked your tester token since it has been inactive for quite some time.

If your token was used with an app or integration (such as a bot), then these integrations will no longer work. We hope there won’t be a disruption, but believe that maintaining the security of your workspace and privacy of your communications is important enough to take this action.

Here are the details of the tester token we've revoked. This action cannot be reversed. Please see the suggestions outlined below about how to generate new tokens by creating a new Slack app:

Token xoxp-xxx-...

There is no further action needed from your side if you are not intending to continue to use this specific token.

That said, if your workspace relies on API tester tokens for bots, integrations, or using the SCIM API, please read https://slack.com/help/articles/215770388 for information on how to issue new authentication tokens. Please note, however, that we are in the process of phasing out API tester tokens and moving towards a "bring your own token" model for testing our API. This means that you should create a Slack app with the appropriate scopes for the API methods you wish to use.

We have updated our API method tester pages so that you can use your own token when submitting a test API request. Previously you were only able to select a generated tester token from the token argument dropdown.

You can create a new Slack app at https://api.slack.com/apps/new. Required scopes for the various API methods are listed at https://api.slack.com/docs/oauth-scopes#oauth_scopes_to_api_methods.

Finally, if you have additional questions you can reach out to an owner on your workspace who may know more about this token or its usage. Otherwise, you can reply directly to this notification - our support team is standing by and ready to help.

So we all can't use this solution any longer?

You can use it with this workaround:
