Facebook Reels Publishing API - Postman Collection

A Postman collection is a set of saved HTTP requests used to learn how to use a specific API. It encloses all the possible calls to an API that can be done, as well as the parameters or headers needed to successfully use it. They encapsulate those resources in a tidy way to save, reuse and share with others. Using them allows developers to quickly onboard and understand the way an API works by generating documented requests with examples. To use the Facebook Reels Publishing API Postman Collection, all that is needed is Postman on web or app and the JSON file containing the requests. This collection allows developers to upload and publish a Reel into a Facebook page from a local file or CDN.
