Synology DSM

Tested Versions

Before You Begin

Common Notes

  1. You are required to utilize a unique client id for every client.
  2. The client id on this page is merely an example and you can theoretically use any alphanumeric string.
  3. You should not use the client secret in this example, We strongly recommend reading the Generating Client Secrets guide instead.
