Configure your Netlify environment variables with the credentials you obtained in step 4.
You can use any serverless backend of your choice for the purpose.
2. Add ArtCart SDK to your Unity project
Import ArtCart SDK package into Unity.
Add an empty object named ArtCart and add the ArtCart script from the SDK to the Object.
Configure the variables in the ArtCart script to point toward your Netlify endpoints:
private string urlawardNFT = "YUOR_NETLIFY_ENDPOINTawardNFT"
private string url_awardSpecificNFT = "YUOR_NETLIFY_ENDPOINTawardSpecificNFT "
At this point, everything should be configured properly.
