I want to identify how many topics a single device is subscribed to. Then I found and followed this post. I don't know if I follow it right because i receive this message
{"error":"MissingAuthorization"}"
Here are the steps:
- Get token from the device
- Generate a URL:
https://iid.googleapis.com/iid/info/<paste token here>
- Copy-paste the URL to the browser
- Get the response.
I don't know if I'm doing something wrong. I hope someone can help me solve this problem.
