Auth can be a pain! My free 2 cents: try authenticating and successfully calling one of your desired endpoints in Postman. If you’re able to get it working in Postman, it’s a Bubble configuration issue. If it isn’t working in Postman, it may be due to how the API service requires you to call the endpoints or some other platform-specific irregularity.

Happy to help and DM’d to learn more in case you want something quick and painless.
