Hello Meta Support Team,

I’m reaching out for assistance with creating a Facebook feed post containing both an image and a video in a single post using Graph API v21.0.

My current setup works well for Facebook when I post images or videos separately. However, I’m encountering consistent errors when trying to combine images and videos into a carousel.

What I've Attempted So Far: - I’ve used the pages_manage_posts and publish_video permissions as required, and my app is configured with all necessary permissions, including: - pages_manage_posts - publish_video - pages_show_list - instagram_content_publish - I’ve tried different configurations, including using the attached_media parameter to include both video and image URLs hosted publicly. - Despite these efforts, I continue to receive errors such as “(#10) Application does not have permission for this action”.

I couldn’t find specific documentation or examples in the official Graph API docs for posting a Facebook feed post that contains both video and image files together. Could you please confirm if this functionality is currently supported? If it is, could you provide guidance on the correct parameters and permissions required to achieve this?

I would greatly appreciate any specific insights or steps I should follow to successfully set up this type of mixed-media post.

By the way it works just fine with Instagram,

Thank you for your time and support!
