Allows users to upload and share files. You can upload any file of up to 5 MB in size. This feature is commonly used in social apps to share images, or in medical apps to share medical records for patients.
When a file is uploaded on a channel, it's stored and managed using a storage service, and associated with your key. Subscribers to that channel receive a file event which contains a file ID, filename, and optional description.
Sending a file is a two-step operation:
- Generate an upload request
- Upload the file using that URL and request body
Retrieving a file is also a two-step operation:
- Request a download URL with a file name and its associated ID
- Download the file using the returned 307 redirect to a time-limited download URL For more information, refer to File Sharing.
