Gatepay SDK

The official TypeScript/JavaScript SDK for the Gatepay API.

Getting Started

🔑 Get Your API Token

Before using this SDK, you need to obtain an API token from the Gatepay dashboard:

👉 Get your API token at gatepay.cloud

Sign up or log in to your Gatepay account
Navigate to the Profile section in your dashboard
Copy the token for use in your application

📚 API Documentation

Gatepay Documentation: https://docs.gatepay.cloud
OpenAPI Specification: https://api.gatepay.cloud/openapi

The API playground allows you to test endpoints directly in your browser and see real-time examples.

Features

✅ TypeScript support with full type definitions
✅ Promise-based API with async/await support
✅ Browser and Node.js compatible

Installation

npm install gatepay-sdk

Quick Start

Create your first link

import { Gatepay } from "gatepay-sdk"

// Initialize the client with your API token
const gatepay = new Gatepay({
    apiToken: "your-api-token", // Get this from https://gatepay.cloud
})

// Account operations
const balance = await gatepay.account.getAccountBalance()
const transactions = await gatepay.account.getAccountTransactions({
    getAccountTransactionsRequest: { page: 1, limit: 10 },
})

// Links operations
const links = await gatepay.links.getLinks({ page: 1, limit: 20 })
const newLink = await gatepay.links.postLinks({
    postLinksRequest: {
        name: "My Link",
        alias: "my-link",
        status: "active",
        type: "permanent",
    },
})

// Networks
const networks = await gatepay.networks.getNetworks()

Convenience Methods

🚀 Enhanced Link Creation

The SDK provides a powerful createLink convenience method that allows you to create a complete link with toll, resource, and actions in a single operation:

// Create a simple link
const simpleLink = await gatepay.createLink({
    name: "My Simple Link",
    alias: "simple-link",
    description: "Basic link for testing",
})

// Create a complex link with payment toll, resource, and actions
const complexLink = await gatepay.createLink({
    name: "Premium Content Access",
    alias: "premium-content",
    description: "Pay to access premium content",

    toll: {
        tollPaymentRequirements: [
            {
                assetNetwork: "base",
                amount: "1000000", // 1 USDC (6 decimals)
                assetAddress: "0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913", // USDC on Base
                destinationAddress:
                    "0x742d35Cc6634C0532925a3b8D098C6dd9f67e235", // Your wallet
            },
        ],
    },

    resource: {
        type: "redirect",
        data: {
            url: "https://example.com/premium-content",
            description: "Premium content page",
        },
    },

    actions: [
        {
            type: "callback",
            trigger: "payment_success",
            data: {
                url: "https://example.com/webhook/payment",
                method: "POST",
            },
        },
    ],
})

createLink Options

The createLink method accepts an object with the following properties:

name (required): string - Link name
alias (optional): string - Link alias for custom URLs
description (optional): string - Link description
toll (optional): object - Payment requirements configuration
resource (optional): object - Resource configuration (redirect, HTML, etc.)
actions (optional): array - Array of actions to execute (webhooks, callbacks)

All types are predefined and auto-generated from the OpenAPI specification, ensuring type safety and consistency with the API.

Toll Payment Requirements Examples

Here are some common toll payment requirement configurations:

// USDC on Base (exact amount)
{
    toll: {
        tollPaymentRequirements: [
            {
                assetNetwork: "base",
                amount: "1000000", // 1 USDC (6 decimals)
                assetAddress: "0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913",
                destinationAddress:
                    "0x742d35Cc6634C0532925a3b8D098C6dd9f67e235",
            },
        ]
    }
}

// ETH on Ethereum (native token)
{
    toll: {
        tollPaymentRequirements: [
            {
                assetNetwork: "ethereum",
                amount: "100000000000000000", // 0.1 ETH (18 decimals)
                assetAddress: "0x0000000000000000000000000000000000000000", // Native ETH
                destinationAddress:
                    "0x742d35Cc6634C0532925a3b8D098C6dd9f67e235",
            },
        ]
    }
}

// MATIC on Polygon
{
    toll: {
        tollPaymentRequirements: [
            {
                assetNetwork: "polygon",
                amount: "1000000000000000000", // 1 MATIC (18 decimals)
                assetAddress: "0x0000000000000000000000000000000000000000", // Native MATIC
                destinationAddress:
                    "0x742d35Cc6634C0532925a3b8D098C6dd9f67e235",
            },
        ]
    }
}

Resource Configuration Examples

Resources define what content users access after payment:

// Redirect to external URL
{
    resource: {
        type: "redirect",
        data: {
            url: "https://example.com/premium-content"
        }
    }
}

// Serve HTML content
{
    resource: {
        type: "html",
        data: {
            content: "<h1>Welcome to Premium Content</h1><p>Thanks for your payment!</p>",
            title: "Premium Content"
        }
    }
}

// Serve file download
{
    resource: {
        type: "file",
        data: {
            url: "https://example.com/files/premium-download.pdf",
            filename: "premium-content.pdf",
            mimeType: "application/pdf"
        }
    }
}

Actions Configuration Examples

Actions are executed when payments are completed:

// Callback notification
{
    actions: [
        {
            type: "callback",
            trigger: "payment_success",
            data: {
                url: "https://yourapi.com/webhooks/payment-completed",
                method: "POST",
            },
        },
    ]
}

// Multiple actions
{
    actions: [
        {
            type: "callback",
            trigger: "payment_success",
            data: {
                url: "https://yourapi.com/webhooks/payment-completed",
                method: "POST",
            },
        },
        {
            type: "callback",
            trigger: "link_accessed",
            data: {
                url: "https://yourapi.com/webhooks/link-accessed",
                method: "POST",
            },
        },
    ]
}

const stats = await gatepay.links.getLinksByLinkUuidStats({
    linkUuid: "link-uuid",
})

// Example: Get account balance (use direct API)
const balance = await gatepay.account.getAccountBalance()

// Example: Get transactions (use direct API)

TypeScript Support

The SDK is written in TypeScript and provides full type definitions:

import Gatepay, {
    GetAccountBalance200ResponseInner,
    PostLinks201Response,
} from "gatepay-sdk"

const gatepay = new Gatepay({ apiToken: "token" })

// Types are automatically inferred
const balance: GetAccountBalance200ResponseInner[] =
    await gatepay.account.getAccountBalance()
const link: PostLinks201Response = await gatepay.createLink({
    name: "Test Link",
    description: "Test description",
})

📖 Documentation

The API playground provides an interactive environment where you can:

Test all API endpoints
See request/response examples
Generate code snippets
Understand the data models

🔑 Authentication

Make sure to:

Keep your API token secure and never expose it in client-side code
Use environment variables to store your API token
Rotate your API token regularly for security

// ✅ Good - Use environment variables
const gatepay = new Gatepay({
    apiToken: process.env.GATEPAY_API_TOKEN,
})

// ❌ Bad - Never hardcode tokens
const gatepay = new Gatepay({
    apiToken: "gp_live_1234567890abcdef", // Don't do this!
})

Environment Support

Node.js 14+ ✅
Browser (ES2017+) ✅
Webpack ✅
Vite ✅
TypeScript 4.0+ ✅
