Hi i want to integrate my thunkable app with xendit payment gateway, here is the xendit website : Best Payment Gateway in Indonesia, Philippines and SEA | Xendit.Please you can read and learn first and then if you know you can do it, we can have a deal. Firstly you can do is make an account in xendit, make a dummy app in thunkable, and then integrate it.
I’ve checked out the xendit API Reference and I can integrate it into your App.
