Getting Started

Initialize the SDK in your project:

import { createWasender } from "wasenderapi";

const apiKey = process.env.WASENDER_API_KEY; // Session-specific API key
const personalAccessToken = process.env.WASENDER_PERSONAL_ACCESS_TOKEN; // Account-level PAT
const webhookSecret = process.env.WASENDER_WEBHOOK_SECRET; // Required for webhook handling

const wasender = createWasender(
  apiKey,
  personalAccessToken,
  undefined, // Optional: baseUrl
  undefined, // Optional: custom fetch implementation
  { enabled: true, maxRetries: 3 }, // Retry configuration
  webhookSecret
