accept-a-payment | customers around the world with a variety of payment methods | Ecommerce library

I hope everything is going fine. I was looking for the payment gateway for the android java. I found stripe but its documentation is very complex to understand. Here is the example UI to understand the problem. All I want to transfer amount from stripe account to the user back account by its card which can be as credit, debit, visa and master etc.
Here are the links I go through but non of them provide complete solution.

• https://stripe.com/docs/connect/charges-transfers
• https://stripe.com/docs/api/transfers/create?lang=java
• https://stripe.com/docs/payments/accept-a-payment
• https://stripe.com/docs/terminal/sdk/android
• https://stripe.com/docs/api

Note: If the question is still unclear, please help me out.

My Angular 11 app uses Stripe Checkout with an Express server to handle the payment. Everything works fine with Angular & Node. I'd like to use Firebase Functions instead of Node, but when I call my Firebase Function, I get the error:

IntegrationError: stripe.redirectToCheckout: You must provide one of lineItems, items, or sessionId.

Angular code:

I've copied the firebase stripe GitHub example index.js and have been fixing the errors which pop up from hosting the code in my index.ts (typescript) file. The error I have left is the following:

Expected 2 arguments, but got 1.ts(2554) index.ts(54, 112): An argument for 'arg1' was not provided.

It's about this line (there are multiple instances although this should not matter to the solution):

I am attempting to integrate stripe payments into a react-redux project following this documentation:

https://stripe.com/docs/payments/accept-a-payment?integration=checkout

The documentation examples assumes React with no Redux. As a result, I am trying to develop an action creator for this portion here:

I have gotten this far:

I have a Stripe checkout page (https://stripe.com/docs/payments/accept-a-payment?integration=checkout) where customers can pay to providers. When I make a test payment, the money appears on the connected account's balance as Total balance, but it's not available to pay out (so Available to pay out amount is 0).

How can I make the money available?

I'm trying to do the simplest possible thing: sending the user to Stripe's hosted checkout page with 1 product.

None of Stripe's examples seem to work, so far what I've got is:

PHP create-checkout-session.php

I need a Stripe Implementation for my Java Android App, but with a Server in Java, I don't know how to use node or php to implement that server-side and I found something on their docs:

https://stripe.com/docs/payments/accept-a-payment?integration=elements#android-create-payment-intent

but, the server-side is poorly explained.

All I've wrote until now is :

I've been trying to implement Stripe with java for testing, but my doubts are step 5 "Create Charge with the token", link for more info. https://stripe.com/docs/payments/accept-a-payment-charges

this is my code:

java controller

I have recently integrated a PayPal payment option to my project and everything is working fine for the amounts of the items in the cart except that after a payment is made the items remain in the cart and there is no payment notified to the backend.

My question is how to set a submit for the address and all the details made in the check out the template along with the paid amount to reflect in the backend.
