Create the Payment Session

❗️
The orderData/orderTag field, present in the service contract, must not be used.

The PaymentSession is a way of initializing a payment with all the necessary data (order informations, customer informations, payment method...) without having to proceed all the different stages yourself.

Having creating a session you will get an URL wich will provide a paymentform, so the customer will be able to complete the payment stages all by himself.

The API route to use is the following :

Integration : POST https://paymentgateway.integration-cb4x.fr/v1/payment-sessions
Production : POST https://paymentgateway.cb4x.fr/v1/payment-sessions

Headers of the request :

Content-type : application/json
authToken : the token retrieved via the call to the authentication service
