When connecting your Instagram business account to your Conversation API app, you may experience one of the following common errors:
This indicates that you selected a Facebook Page that's not configured to connect with the corresponding Instagram account. Make sure that the Facebook Page and Instagram business account are connected by following these steps.
This indicates that more than one new viable setup was configured. Make sure that you select only one available (that is, unselected) Instagram account and one available (that is, unselected) Facebook Page when configuring the Instagram channel. Do not edit any other existing selections, as you may invalidate other Conversation API apps.
This indicates that you didn't select any Pages during the login process. Make sure that you select a single Instagram account and a single Facebook Page when configuring your Instagram channel on the Conversation API.
This error may also occur if the Conversation API app wasn't given the required permissions during the final login step. Make sure all permissions are enabled.
This could occur for a few reasons:
This indicates that the Page you selected is already configured in another Conversation API app. If you wish to connect this Page to your current app, remove the existing Instagram integration from the other Conversation API app. For information on how to remove an Instagram integration, click here.
This is an error message that is provided by Meta. In the context of your Conversation API app, this may mean that your app's access to Instagram's messaging functionality has not been enabled for your Instagram business account. Verify that tools that are connected to your Instagram account have access to Instagram Messages. To do so, follow the instructions here and ensure that "Allow access to Messages" has been enabled.
