    Deprecating the Link Application endpoint

    Tagged: Marketing, Deprecation

    What

    We removed the largely unused Link Application endpoint due to security concerns.

    Why

    We previously supported a POST /authorized-apps endpoint that let you post the client credentials for an app, and receive a new API token associated with that app.

    This would register an app to the users’ account in a way that isn’t transparent to the user, so to improve security, we removed this feature.

    The endpoint was accessed by only a handful of accounts over the last few months, so most API users will not be impacted.
