Lindy SDK & Integration Patterns

Lindy SDK & Integration Patterns

Overview

Lindy is primarily a no-code platform. External integration happens through three channels: Webhook triggers (inbound), HTTP Request actions (outbound), and Run Code actions (inline Python/JS execution via E2B sandbox). This skill covers patterns for each.

Prerequisites

• Lindy account with active agents
• Node.js 18+ or Python 3.10+ for webhook receivers
• Completed lindy-install-auth setup

Pattern 1: Webhook Trigger Integration

Your application fires webhooks to wake Lindy agents:

// lindy-client.ts — Reusable Lindy webhook trigger client
class LindyClient {
  private webhookUrl: string;
  private secret: string;

  constructor(webhookUrl: string, secret: string) {
    this.webhookUrl = webhookUrl;
    this.secret = secret;
  }

  async trigger(payload: Record<string, unknown>): Promise<{ status: number }> {
    const response = await fetch(this.webhookUrl, {
      method: 'POST',
      headers: {
        'Authorization': `Bearer ${this.secret}`,
        'Content-Type': 'application/json',
      },
      body: JSON.stringify(payload),
    });
