Integration of CRM with the PayU payment service

When transferring the deal to the "Send Invoice" stage in CRM, the system automatically initiates integration:
Customer data and deal parameters (amount, currency, description) are extracted from CRM
An API request is formed to PayU to create a customer card and generate a payment link
Within 5 seconds, the ready link is returned and saved in the deal card
The sales manager immediately gains access to the link and can send it to the client
