Please add IAM support for the Facebook Social Planner OAuth start route:

GET /social-media-posting/oauth/facebook/start

We are building a third-party application that allows users to connect their Facebook Page from within our app.

The equivalent Instagram OAuth route works correctly, but attempting to use the Facebook route returns:

“This route is not yet supported by the IAM Service. Please update your IAM config.”

The Private Integration already has the required Social Planner scopes enabled, including:

socialplanner/oauth.readonly

socialplanner/oauth.write

socialplanner/account.readonly

socialplanner/account.write

It would be useful for Facebook OAuth to support IAM/Private Integration authentication in the same way as the equivalent Instagram flow, allowing users to connect their Facebook Page without needing to enter the HighLevel UI.

This would enable SaaS applications built on HighLevel to offer a fully branded/self-service Facebook connection experience.
