Cakemail SDK

TypeScript SDK for the Cakemail API.

Installation

npm install @cakemail-org/cakemail-sdk

Quick Start

import { CakemailClient } from '@cakemail-org/cakemail-sdk';

// Initialize the client
const client = new CakemailClient({
  email: 'your-email@example.com',
  password: 'your-password',
});

// Get current account
const account = await client.accounts.getSelf();
console.log('Account:', account);

// List contacts
const contacts = await client.contacts.list({
  page: 1,
  per_page: 20,
  status: 'active',
});
console.log('Contacts:', contacts.data);

Configuration

Email/Password Authentication

const client = new CakemailClient({
  email: 'your-email@example.com',
  password: 'your-password',
});

Access Token Authentication

If you already have an access token from an external OAuth flow, you can use it directly:

const client = new CakemailClient({
  accessToken: 'your-access-token',
  refreshToken: 'your-refresh-token', // Optional but recommended
  expiresIn: 3600, // Optional: Token expiration in seconds (default: 3600)
  scope: 'read write', // Optional: Token scope (default: 'read write')
});

Use cases for access token authentication:

• Web applications with browser-based OAuth flows
• Service accounts with pre-generated tokens
• Integration with external authentication systems
• Token-based authentication without storing passwords

Note: If a refreshToken is provided, the SDK will automatically refresh expired access tokens. Without a refresh token, you'll need to provide a new access token when the current one expires.

Advanced Configuration

const client = new CakemailClient({
  email: 'your-email@example.com',
  password: 'your-password',
  baseURL: 'https://api.cakemail.dev', // Optional: Custom API URL
  timeout: 30000, // Optional: Request timeout in ms (default: 30000)
  maxRetries: 3, // Optional: Max retry attempts (default: 3)
});

Multi-Tenant Operations

For parent accounts managing child accounts, you can specify an accountId option:

// Access child account data
const childContacts = await client.contacts.list(
  { status: 'active' },
  { accountId: 456 } // Child account ID
);

// Create resource in child account
const newContact = await client.contacts.create(
  {
    email: 'new@example.com',
    first_name: 'John',
  },
  { accountId: 456 }
);

Error Handling

The SDK provides detailed error types for better error handling:

import {
  CakemailError,
  CakemailAPIError,
  CakemailAuthError,
  CakemailNetworkError,
  CakemailValidationError,
} from '@cakemail-org/cakemail-sdk';

try {
  const contact = await client.contacts.get(999);
} catch (error) {
  if (error instanceof CakemailAPIError) {
    console.error('API Error:', error.getUserFriendlyMessage());
    console.error('Status Code:', error.statusCode);
    console.error('Response:', error.responseBody);
  } else if (error instanceof CakemailAuthError) {
    console.error('Authentication failed:', error.message);
  } else if (error instanceof CakemailNetworkError) {
    console.error('Network error:', error.message);
  } else if (error instanceof CakemailValidationError) {
    console.error('Validation error:', error.message);
  }
}

User-Friendly Error Messages

API errors include user-friendly messages via getUserFriendlyMessage():

try {
  await client.contacts.create({ email: 'invalid-email' });
} catch (error) {
  if (error instanceof CakemailAPIError) {
    // Shows: "Invalid request: Invalid email format. Please check your parameters."
    console.error(error.getUserFriendlyMessage());
  }
}

Authentication

Automatic Token Management

The SDK automatically handles OAuth 2.0 token lifecycle:

• Authenticates on first API request
• Caches access tokens
• Refreshes tokens before expiration (5-minute buffer)
• Retries failed requests after token refresh

Manual Authentication

// Explicitly authenticate (optional)
await client.authenticate();

// Get token information
const tokenInfo = client.getTokenInfo();
console.log('Token valid:', tokenInfo.isValid);
console.log('Expires at:', new Date(tokenInfo.expiresAt!));

// Clear cached token (forces re-authentication)
client.clearAuthCache();

Retry Logic

The SDK automatically retries failed requests with exponential backoff:

• Network errors: Retries automatically
• 5xx server errors: Retries automatically
• 401 errors: Refreshes token and retries once
• Max retries: 3 attempts (configurable)
• Backoff: 1s, 2s, 4s, 8s (max 10s)

TypeScript Support

The SDK is written in TypeScript and includes comprehensive type definitions:

import {
  Account,
  Contact,
  List,
  Campaign,
  CreateContactRequest,
  UpdateContactRequest,
  ContactStatus,
  CampaignStatus,
} from '@cakemail-org/cakemail-sdk';

const contact: Contact = await client.contacts.get(123);

const createRequest: CreateContactRequest = {
  email: 'new@example.com',
  first_name: 'John',
  status: ContactStatus.Active,
};

Command-Line Interface

For quick testing, automation scripts, and terminal access, the Cakemail CLI is also available:

Installation:

# via Homebrew (macOS/Linux)
brew tap cakemail/cakemail
brew install cakemail-cli

# via npm
npm install -g @cakemail-org/cakemail-cli

# via npx (no installation)
npx @cakemail-org/cakemail-cli --help

Example usage:

cakemail campaigns list
cakemail contacts create --email user@example.com --first-name John
cakemail campaigns send --id 123

The CLI uses this SDK internally and is ideal for:

• Quick testing and debugging
• DevOps automation and CI/CD pipelines
• Non-developer users (marketers, operations teams)
• Scripting and batch operations

See the CLI documentation for complete details.
