We have a desktop CRM software that manages repair jobs (repairs). And issue invoices for these repair jobs, to bill the customer. Right now, when we issue an invoice for a customer, we generate a pdf of the invoice and we email it to the customer with some plain text. Requirement: We would like to be able to use the WebAPI to generate a PayPal payment link so we can include it to our email, so the customer can pay it in his convenient time. Attention: Because our desktop program is purchased by many different companies and those different companies they use it to their business, we have a settings page in the desktop program, so each company that purchase and use the software can save their own (Paypal API details like client id and client secret keys). We also have a unique company id for each different company that is purchasing and install and use the program. This is so we can track, to which company belong the certain paypal api key (client id and client secret). Requirements. 1. TASK 1. The middleware WEB API will need to be able to retrieve the paypal link generation request from our desktop program securely, store the request detail in his local mysql database and process(handle) the request to generate the paypal payment link and return it back as a string to the desktop program. 2. TASK 2. When the payment link is paid from the customer the WEBAPI must be able to capture this event (via the paypal callback event) and save the date/time/transactionid/paypal response and any other info we might need to know so we can detect from our desktop program if the certain payment is paid or not.

Hello, I understand that you need a secure middleware WEB API that connects with your desktop CRM to generate PayPal payment links. This API will store the requests in a MySQL database, process them to create payment links, and return these links securely. Additionally, I will ensure that the API captures transaction events from PayPal, including successful payments and failed attempts, allowing you to track payment statuses linked to specific invoices. I will prioritize secure communication and detailed logging of all payment attempts to provide historical data for each transaction. Could you clarify the specific fields that need to be stored for each payment attempt and the exact information you require from the PayPal callback event? Thanks, Muhammad Awais

Failed payment attempts will also be logged, providing a comprehensive history of all interactions for better insight into payment behavior. My experience includes implementing secure payment solutions and callback handling in similar projects, ensuring data integrity and real-time updates.

Hello, I understand that you need a secure middleware WEB API that integrates with your desktop CRM to handle PayPal payment link generation and payment event tracking. The API will need to securely receive requests, store them in a MySQL database, and generate payment links while also capturing and logging payment events, including successes and failures, to ensure you can track invoice payments effectively. My approach will involve developing a RESTful API that communicates seamlessly with your desktop application and utilizes PayPal's callback events to capture necessary transaction details and payment attempts. This will ensure you have a clear historical view of payment activities. Could you clarify the desired authentication method for securing the API and any specific requirements for data encryption? Thanks, Shamshad
