# 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: ```typescript // 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), }); if (!response.ok) { throw new Error(`Lindy webhook failed: ${response.status} ${response.statusText}`); } return { status: response.status }; } async triggerWithCallback( payload: Record<string, unknown>, callbackUrl: string ): Promise<{ status: number }> { return this.trigger({ ...payload, callbackUrl }); } } ...
