REST API for processing p2p payments

Hello! 🌟

My name is Semen, I am a web developer with experience in integrating payment systems on websites. I have reviewed your request: you need to integrate payments on your site, there is documentation and an implementation example. I am ready to complete this task efficiently and promptly! 🚀

📋 Implementation Plan:

Website and documentation analysis:
I will familiarize myself with your website, documentation, and implementation example to understand the technical requirements.
I will determine which payment system will be integrated (for example, LiqPay, Fondy, or another).
… Preparation for integration:
I will check your website: what CMS (for example, WordPress, OpenCart) or if there is a custom development.
I will set up the necessary accounts: I will register a merchant account in the payment system and obtain API keys.
Integration of the payment system:
Based on the implementation example, I will connect the payment system:
If it is an API integration, I will add code to the backend (for example, PHP for processing requests).
On the frontend, I will implement a payment form (for example, a "Pay" button that redirects to the payment page).
I will ensure security: I will use HTTPS, check PCI DSS compliance (as recommended for payment integrations [Ref web ID: 0]).
Testing:
I will conduct test transactions in sandbox mode (as advised in [Ref web ID: 0, 1]) to ensure that payments are processed correctly.
I will check scenarios: successful payment, decline, errors.
Launch and support:
I will switch the system to live mode after testing.
I will set up transaction notifications for you and clients.

💰 Cost and timelines:
Payment integration: $200.
Testing and setup: $50.
Total: $250.
Timeline: 3–5 days.
Support: $50/month (if needed).

❓ Next steps:
Provide access to documentation and the implementation example.
Give access to the website (admin panel, hosting).
Specify which payment system needs to be integrated.
I will start after agreement!
Best regards, Semen 😊

Good day, I am on Freelancehunt for the first time, but I think I can take on this task. I do not know all the conditions of the task, so I cannot provide a specific price.
