Uploading Media

GroupMe provides its own Content Delivery Network (CDN) to host images, videos, and other files that can be attached to messages. To send a message with a media attachment, you must first upload the file to the appropriate GroupMe service. This process will return a URL on the GroupMe CDN that you can then use in your API calls.

This is a two-step process:

1. Upload: Send your media file to the correct upload service.
2. Attach: Use the URL returned in Step 1 to create a message with an image, video, or file attachment.
