Gumroad API Client

A TypeScript/JavaScript client for interacting with the Gumroad API. This library provides a simple and intuitive way to interact with the Gumroad API, supporting all major endpoints. It includes interfaces for various data types returned by the API, as well as classes for managing licenses and subscriptions.

Installation

To install the library, use the following command:

> npm install smashroad

Usage

First, import the GumroadClient class from the library:

import { GumroadClient } from 'smashroad';

Then, create a new instance of the client, passing your Gumroad API access token, product id, and cookie as parameters to the constructor:

const client = new GumroadClient('YOUR_ACCESS_TOKEN', 'YOUR_PRODUCT_ID', 'YOUR_GUMROAD_COOKIE');

You can now use the client to interact with the Gumroad API. For example, to get a license:

const license = await client.getLicense('LICENSE_KEY', 'PRODUCT_ID');

API

GumroadClient

The main class for interacting with the Gumroad API. It provides methods for making requests to the API, managing resource subscriptions, and working with licenses and subscriptions.

Constructor

new GumroadClient(access_token: string, product_id?: string, cookie?: string)

• access_token: Gumroad API access token
• product_id: (Optional) Gumroad product id
• cookie: (Optional) Gumroad cookie. You can get this from the browser when you're logged in to Gumroad.

Methods

public async getResourceSubscriptions(resource_name : ResourceSubscriptionType) : Promise<ResourceSubscription[]>

public async createResourceSubscription(resource_name: ResourceSubscriptionType, post_url: string) : Promise<ResourceSubscription>

public async getLicense(license_key: string, product_id: string): Promise<GumroadLicense>

public async getSubscriptionPurchases(subscription_id: string): Promise<Purchase[]>

public async searchPurchases(query: string): Promise<Purchase[]>

public async getSubscriptions(email?: string, product_id?: string): Promise<Subscription[]>

public async emailIsSubscriber(email: string, product_id ?: string): Promise<boolean>

public async getSubscription(subscription_id: string): Promise<Subscription>

GumroadLicense

A class for managing a Gumroad license. It provides methods for getting charges, purchases, and subscription information, as well as checking the validity and status of the license.

Constructor

new GumroadLicense(initiatingPurchase: Purchase, client: GumroadClient)

Methods

async getCharges(): Promise<Purchase[]>

async getPurchases(): Promise<Purchase[]>

async getSubscription(): Promise<Subscription>

async isValid(invalidCases?: InvalidCases): Promise<boolean>

async getStatus(): Promise<string>

async getTotalRevenue(): Promise<number>

Examples

Here's an example of how to use the GumroadClient to get a license:

const client = new GumroadClient('YOUR_ACCESS_TOKEN', 'YOUR_PRODUCT_ID', 'YOUR_GUMROAD_COOKIE');
const license = await client.getLicense('LICENSE_KEY', 'PRODUCT_ID');
console.log(await license.getStatus());

And here's an example of how to use the GumroadLicense to check if a license is valid:

const client = new GumroadClient('YOUR_ACCESS_TOKEN', 'YOUR_PRODUCT_ID', 'YOUR_GUMROAD_COOKIE');
const license = await client.getLicense('LICENSE_KEY', 'PRODUCT_ID');
try {
const isValid = await license.isValid();
console.log('License is valid');
} catch (error) {
console.error('License is invalid:', error.message);
}

Types

The library includes TypeScript definitions for various Gumroad API response types, including:

• Purchase
• Subscription
• ResourceSubscription
• GumroadSaleData
• GumroadSubscriptionData
• SubscriptionUpdateData
• SubscriptionEndedData
• SubscriptionRestartedData

These types can be imported and used in your TypeScript projects for better type checking and autocompletion.

Error Handling

The library throws errors for invalid API responses or when a license is invalid. Make sure to wrap your API calls in try-catch blocks to handle these errors gracefully.
