+## API (Sylius Api Platform)
+
+### Stripe JS gateway
+
+The endpoint : `GET /api/v2/shop/orders/{tokenValue}/payments/{paymentId}/configuration`
+will make a Payum `Capture` and respond with the Stripe Payment Intent client secret, like this :
+
+```json
+{
+ 'publishable_key':  'pk_test_1234567890',
+ 'use_authorize': false,
+ 'stripe_payment_intent_client_secret': 'a_secret'
+}
+```
+
+After calling this endpoint your will be able to use Stripe Elements to display a Stripe Payment form, the same as this template is doing it:
+https://github.com/FLUX-SE/PayumStripe/blob/master/src/Resources/views/Action/stripeJsPaymentIntent.html.twig.
+More information here : https://docs.stripe.com/payments/payment-element
+
+### Stripe Checkout Session gateway
+
+The endpoint : `GET /api/v2/shop/orders/{tokenValue}/payments/{paymentId}/configuration`
+will make a Payum `Capture` and respond with the Stripe Checkout Session url, like this :
+
+```json
+{
+ 'publishable_key':  'pk_test_1234567890',
+ 'use_authorize': false,
+ 'stripe_checkout_session_url': 'https://checkout.stripe.com/c/pay/cs_test...'
+}
+```
+
+Since this endpoint is not able to get any data from you, a service can be decorated to specify the Stripe Checkout Session `success_url` you need. 
+Decorate this service : `flux_se.sylius_payum_stripe.api.payum.after_url.stripe_checkout_session` to generate your own dedicated url.
+You will have access to the Sylius `Payment` to decide what is the url/route and the parameters of it.
