Maximum of 30 total assets. For example, you have 28 assets with 10 images, 5 bodies, 5 titles, 5 description, 1 ad_format, 1 link_url, and 1 call_to_action_types.
Total number of images: <= 10.
Total number of videos: <= 10. If you use Instagram as your placement, only square videos or landscape videos allowed.
Total number of bodies: <= 5.
Total number of call-to-actions: <= 5.

Total number of links: <= 5.
Total number of descriptions: <= 5.

Image requirements:

Recommended image specs: 1.9:1.
Recommended image size: 1,200 x 628 pixels.
For CAROUSEL_IMAGE format, you must provide at least 2 images.
If you use Instagram as your placement, use square images for better performance.

APP_INSTALLS
CONVERSIONS
LINK_CLICKS

Add deeplink_url in link_urls when you create your asset_feed_spec.
