BitPayConnect Self-Custody App – Your Decentralized Crypto Payment Gateway

About BitPayConnect Self-Custody App

BitPayConnect is a powerful decentralized crypto payment gateway designed to give merchants complete control over their cryptocurrency transactions. Unlike traditional payment processors, BitPayConnect allows you to accept crypto payments directly from customers without relying on third-party exchanges or custodial services.

This payment gateway using blockchain technology ensures secure, fast, and private transactions with zero commissions—just the standard blockchain network fee. Whether you're running a website or a mobile application, BitPayConnect turns your device into a fully operational crypto payment gateway , offering real-time payment syncing and decentralized wallet management.

With no KYC requirements , all data stored locally on your device, and support for multiple platforms, BitPayConnect is ideal for privacy-conscious businesses, developers, and crypto-native merchants.

Key Features

Convert Crypto to Fiat – Stay Compliant and In Control

While BitPayConnect allows you to receive crypto payments in a fully decentralized and self-custodial environment, converting those assets into fiat currency is just as important for real-world business use.

To convert your cryptocurrency holdings to fiat (like INR, USD, or EUR), you can use any legal crypto exchange registered in your country. This process is handled entirely outside of the BitPayConnect app, ensuring you remain in control of your funds and compliant with local financial regulations.

There are no built-in fiat services or third-party custodians involved— you choose your preferred exchange , initiate the transfer manually, and handle your tax obligations directly.

This ensures that your use of crypto stays decentralized, secure, and legally compliant, without compromising on privacy or control.

Integration Specifications

The BitPayConnect Self-Custody API allows merchants to integrate decentralized crypto payments into their platforms without relying on third-party gateways. It includes endpoints for retrieving customer data (get-customer), storing user-specific wallet addresses (generated-wallet), and receiving real-time payment notifications via webhook (payment-received). Also need to specify api key in the app if you want to authenticate request.

Merchants must create these endpoints on their servers in the exact request and response format defined in the specification. Once created, the endpoint URLs must be configured within the BitPayConnect app settings to enable secure, real-time communication between the app and your backend system.

This setup ensures full control, privacy, and functionality for accepting crypto payments across websites and mobile apps using self-custody architecture.

How to Connect BitPayConnect to Your Website or App

Step 1: Install the App

Download and install the BitPayConnect Self-Custody App on your device. Set a secure PIN — no KYC or account creation required.

Step 2: Create Required API Endpoints

On your server or backend, create the following REST API endpoints:

/api/get-customer – Returns user details when a new user signs up.

/api/generated-wallet – Accepts a wallet address from the app.

/api/payment-received – This endpoint is triggered by the app to notify your platform instantly when a cryptocurrency payment is detected. It ensures timely updates to your system by delivering transaction details via a webhook.

Important: Follow the exact request/response format provided in the API spec.

Step 3: Configure API URLs in the App

In the BitPayConnect app, enter the full URLs of the above endpoints in the API Settings section:

Add base URL (e.g., https://yourdomain.com/api/)

Map each function to the correct endpoint path

Step 4: Integrate Signup with App (Optional)

When a user registers on your website or app, the BitPayConnect system automatically reaches out to your backend using this endpoint to fetch their information. This data is then used by the app to generate and assign a dedicated crypto wallet.

Step 5: Wallet Creation & Sync

The app generates static crypto wallets for each user and sends them to your system via the generated-wallet API. These wallets are used for future payments.

Step 6: Receive Payment Updates via Webhook

When a payment is detected on-chain, the app automatically calls your payment-received endpoint with full transaction details. This keeps your website or app in sync with blockchain activity.

Step 7: Secure & Monitor

Ensure your server is HTTPS-enabled, and validate all incoming requests to protect against misuse. The app stores data only on your device — keep it powered and open to ensure real-time updates.
