Integration

Two convenient methods are available to integrate our mini-app for receiving cryptocurrency payments.

1. Payment Button via Script

You can integrate the payment system into your service or mini-app by adding a pre-built button script. This is a quick and easy way to set up the payment process via the TON network in widely used wallets.

Script Integration

To enable the payment button, add the script to your service:

<script src="https://cdn.onchainpay.io/images/PaymentButtonMiniApp.js"></script>

Example of a payment button tag with required parameters:

<payment-button
    data-orderid="test"
    data-organizationid="your_organization_id"
    data-description="test"
    data-payeremail="[e-mail]"
    data-apikey="your_public_api_key"
    data-label="Pay"
    data-accentcolor="red"
    data-returnurl="https://example.com/success"
>
</payment-button>

Note! data- attributes must be written in lowercase.

Payment Button Parameters

data-label

The text displayed on the button.

Example: data-label="Pay"

data-accentcolor

Button color. Available values: purple, orange, green, red, yellow, blue

2. Direct Link

Alternatively, you can use a direct link that you can embed into your service or mini-app. This link redirects the user to our payment app within Telegram.

To open the payment mini-app, you need to generate a base64 string from the parameters and insert it into the startapp query parameter.

Example of Generating a Base64 String in JavaScript:

const encodeObjectToUrlString = (obj) => { 
  const jsonString = JSON.stringify(obj); // Convert object to JSON string 
  return encodeURIComponent(btoa(jsonString)); // Encode to Base64 and make URL-safe 
};

// Example usage:
const params = {
  apiKey: "apiKey",
  orderId: "Payment#1234",
  description: "Some payment description",
  organizationId: "organizationId",
  payerEmail: "[e-mail]",
  returnUrl: "https://example.com/success"
};

const base64Params = encodeObjectToUrlString(params);

Example of a Link:

https://t.me/Onchainapay_app_bot/onchainpay?startapp=${base64Params}

You can open the link using the window.open function:

window.open(`https://t.me/Onchainapay_app_bot/onchainpay?startapp=${base64Params}`);

Insert the result from the base64Params function into the URL string.
