1. How to Integrate Stripe Payment with Liferay: A
Step-by-Step Guide
Introduction
• There is mainly two ways to implement stripe payment integration
1.Prebuit Payment Page:
• This payment provides by the stripe so we no need to code for it.
• It has all functionality coupon for discount, etc
• UI part for the payment integration is fixed. We cannot change it.
• Need to create product in the stripe dashboard.
• And only passing quantity at payment time total price and discount all those
things managed by the stripe.
2. Custom Payment flow:

2. • This flow will use when we have custom payment page or different design
• And customisation from the payment side and only user will do payment only
not specify any product.
• In this flow, no need to create Product for the payment.
• Need to create below APIs
• Create-payment-intent API: add payment related detail in the stripe. It will
return client_secret for make payment.
• Webhook
• Confirm Payment: It will take card detail and client_secret that we got from the
create-payment-intent API.
Object Definition for the Stripe
Introduction
• We are using the stripe for payments but in feature there might be
client will use other payment service provider use.
• So, using two object we will handle it

type, and relation with Calander Event Payment object

P-Flow for the Stripe payment integration
• We will perform the below operations for Stripe payment integration in the
Calander event.
• Create a customer in Stripe while the Liferay user gets created.
• Add create a customer in register API
• Also, while the Liferay user gets created using the Liferay admin panel
• Create Payment Intent API for adding payment related in the stripe and take
payment stripe ID for confirm Payment
• Add the same detail in the Liferay object with event data (status – pending)
while they call payment intent API.
• After creating the Payment Intent API success response, FE will call Liferay
Object API to set payment detail in the Object and status pending.
• Confirm Payment with Payment Intent stripe Id, email, and card detail

4. • Create Webhook API that will call by the stripe while any update is there
related to the specified e.
• After successful payment, Webhook API will call to update the status (status –
success or failed)
• In webhook based on the switch case, we will update its status in Liferay
Object
o
Create Payment Intent API
→ Using Payment Intent API, we are insert transaction data and status as
incomplete in the stripe, so it takes few parameters like Liferay user id,
calendar event id, stripe customer id, total amount and currency. It will return
payment Intent id and client secret.
Get User Payment Detail Id if Not Prent Then Add
→ Get Parent object Id from the below API for passing it into
→ We need id of the parent object to make relationship so we will call user
payment details headless API by passing the Liferay user id from the session
storage. It will return id in the items for the POST eventpayments API.

5. • If above API items tab is empty, then you need to add user related data in the
user payment details object and take id from response and pass it in POST
eventpayments API.

6. Add Data in Calendar Event Payment
Object
• The calendar Event object is used to track the event payment transaction data
in our database.
• To add an entry in the calendar event object after the payment intent success
response because we are passing payment intent id as transaction id in the
Object.
• Add prices, quantity, payment status (default – in Complete), tax amt, total
amt, transaction Id(Id from the create payment intent response),
r_event_c_payment_id(id from the userpaymentdetails headless API), site id
as 20119 as default value.
