Help Stream Video

stream

#1

I can not integrate the video stream with PHP, I am in the cloudflare documentation, stream video, and I have the KEY and E-mail credentials requested on this page: https://api.cloudflare.com/#stream-videos-initiate-a-video-upload
But I do not know which fields to send, and I do not know how to proceed, working with Guzzle or native PHP CURL, please I need help!
