Get started with Processing API

The typical flow for using the Processing API is:

1. Request an upload URL.
2. Upload recording to the provided URL. Use HTTP PUT and set right ContentType.
3. Start session processing with the upload URL and session metadata. Keep the returned processingId.
4. Wait for the webhook to be called informing that the session processing or session note processing is finished.
5. Download insights for the processingId.
6. Delete all produced data for the processingId.
