I’m using Stripe.js by @copilot and using it with a workflow that creates a customer in Stripe, saves the Stripe customer ID, and then tries to run the “Create Card” call but nothing seems to happen.
If you’re on Version 1.9.0 or higher, you’re within the Beta boundaries of the upcoming Stripe.js 2.0 release. You should consider downgrading to Version 1.8.10 or lower, just in case.
It looks like you are not prefixing your credentials with 'Bearer ', which is stated explicitly in the error message. Reading error messages is the best way figure out next steps when running into problems, sometimes providing the solution right in the description.
Additionally, it’s always a better idea to follow a plugin developer’s suggested method of communication in order to get bugs addressed sooner. Even though your post is not detailing a bug, you should’ve given (us in this case) a shout at plugins@withcopilot.com before posting.
