Services Configuration - Mixpost
To be able to post on Facebook and Instagram, you must create and configure a Facebook application. Because Facebook and Instagram belong to the same company Meta.
Step 1: Create a Developer Account
To create a Facebook app, you must first have a Facebook developer account. If you don't already have one, go to the Facebook for Developers website and click "Get Started" in the top right corner. Follow the instructions to sign up for a developer account.
Step 2: Create a New App
Once you have a developer account, go to the Facebook Developer Dashboard and click "Create App" in the top right corner. Choose "Business" as the app type and give your app a name.
