Did you find the solution ? Still experiencing the same issue ! Works with HS256 and doesn't with RS256. Is it google cloud kind of limitation ?

Thank you so much ! @dbburgess

Problem: Was using the wrong key and email. These should be generated in the Google Cloud credentials section that corresponds to the Firebase project.

Solution:

• Go to 'console.cloud.google.com'.
• Select the related Firebase project.
• Then 'API Manager' -> 'Credentials'.
• 'Create Credentials' -> 'Service Account Key' -> Choose JSON.
• The created file will contain the needed 'private_key' & 'client_email'.

Fill the values:

$service_account_email = "autogeneratedemail@developer.gserviceaccount.com"; $private_key = "-----BEGIN PRIVATE KEY-----\nSoneVeryVeryLongKey=\n-----END PRIVATE KEY-----\n"; $uid = 'UserToUseInFirebaseRules'; $is_premium_account = $uid;

You shouldn't need to change anything in the "create_custom_token" function, maybe the expiration date/time according to your needs.

Then call the function:

create_custom_token($uid, $is_premium_account);
