Hi,
I'm doing augmented reality project using Unity and Photon (this tutorial: https://www.youtube.com/watch?v=wg9KY4TH__w&t=25s). In the tutorial the link given to connect Unity and Particle Photon is as follow:
https://api.particle.io/v1/devices/events?access_token= 123456789900
However I fail to make the connection. Is there any new link for that purpose (The tutorial is 8 years old)?
Thank you.
You can no longer pass the access_token in the query string of the URL. Instead, you must pass the access token in an Authorization header. See how to send your access token.
I'm not familiar with Unity, but it looks like you might use SetRequestHeader.
This is the code in Unity to get the data from Particle Photon. Just in case you are familiar with the format.
