Lindy CI Integration

Overview

Lindy agents run on Lindy's managed platform — CI/CD tests your integration code: webhook receivers, callback handlers, and application logic that interacts with Lindy agents. Test webhook signature verification, payload processing, and error handling without hitting live Lindy endpoints.

Prerequisites

• GitHub repository with Actions enabled
• Lindy API key and webhook secret stored as GitHub secrets
• Node.js project with webhook receiver code
• Completed lindy-install-auth setup

Instructions

Step 1: Store Secrets in GitHub

gh secret set LINDY_API_KEY --body "lnd_live_xxxxxxxxxxxx"
gh secret set LINDY_WEBHOOK_SECRET --body "whsec_xxxxxxxxxxxx"

Step 2: Create GitHub Actions Workflow

# .github/workflows/lindy-integration.yml
name: Lindy Integration Tests

on:
  push:
    branches: [main]
  pull_request:
    branches: [main]

jobs:
  test:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - uses: actions/setup-node@v4
        with:
          node-version: '20'
          cache: 'npm'

      - run: npm ci

      - name: Run unit tests
        run: npm test
        env:
          LINDY_WEBHOOK_SECRET: ${{ secrets.LINDY_WEBHOOK_SECRET }}

      - name: Validate webhook handler
        run: npm run test:webhook

      - name: Connectivity check (non-blocking)
        continue-on-error: true
        run: |
          curl -s -o /dev/null -w "%{http_code}" \
            -X POST "https://public.lindy.ai/api/v1/webhooks/health" \
            -H "Authorization: Bearer ${{ secrets.LINDY_API_KEY }}"

Step 3: Write Webhook Handler Tests

// __tests__/webhook-handler.test.ts
import { describe, it, expect, vi } from 'vitest';
import request from 'supertest';
import { app } from '../src/server';

describe('Lindy Webhook Handler', () => {
  const VALID_SECRET = process.env.LINDY_WEBHOOK_SECRET || 'test-secret';

  it('rejects requests without auth header', async () => {
    const res = await request(app)
      .post('/lindy/callback')
      .send({ event: 'test' });
    expect(res.status).toBe(401);
  });

  it('rejects requests with wrong auth token', async () => {
    const res = await request(app)
      .post('/lindy/callback')
      .set('Authorization', 'Bearer wrong-token')
      .send({ event: 'test' });
    expect(res.status).toBe(401);
  });

  it('accepts requests with valid auth token', async () => {
    const res = await request(app)
      .post('/lindy/callback')
      .set('Authorization', `Bearer ${VALID_SECRET}`)
      .set('Content-Type', 'application/json')
      .send({
        taskId: 'task_123',
        status: 'completed',
        result: { summary: 'Test result' },
      });
    expect(res.status).toBe(200);
    expect(res.body.received).toBe(true);
  });

  it('handles malformed payload gracefully', async () => {
    const res = await request(app)
      .post('/lindy/callback')
      .set('Authorization', `Bearer ${VALID_SECRET}`)
      .set('Content-Type', 'application/json')
      .send('not-json');
    expect(res.status).toBeLessThan(500);
  });

  it('processes webhook payload fields correctly', async () => {
    const payload = {
      taskId: 'task_456',
      status: 'completed',
      result: {
        classification: 'billing',
        sentiment: 'neutral',
        summary: 'Customer asks about invoice #789',
      },
    };

    const res = await request(app)
      .post('/lindy/callback')
      .set('Authorization', `Bearer ${VALID_SECRET}`)
      .set('Content-Type', 'application/json')
      .send(payload);

    expect(res.status).toBe(200);
  });
});

Step 4: Add Smoke Test for Live Connectivity

// __tests__/connectivity.test.ts
import { describe, it, expect } from 'vitest';

describe('Lindy Connectivity (smoke)', () => {
  it('can reach Lindy webhook endpoint', async () => {
    const webhookUrl = process.env.LINDY_WEBHOOK_URL;
    if (!webhookUrl) {
      console.warn('LINDY_WEBHOOK_URL not set, skipping connectivity test');
      return;
    }

    const response = await fetch(webhookUrl, {
      method: 'POST',
      headers: {
        'Authorization': `Bearer ${process.env.LINDY_WEBHOOK_SECRET}`,
        'Content-Type': 'application/json',
      },
      body: JSON.stringify({ test: true, ci: true }),
    });

    expect(response.ok).toBe(true);
  });
});

Step 5: PR Status Check

# Add to existing workflow
      - name: Post test results
        if: always()
        uses: actions/github-script@v7
        with:
          script: |
            const status = '${{ job.status }}' === 'success' ? 'Passed' : 'Failed';
            if (context.payload.pull_request) {
              github.rest.issues.createComment({
                owner: context.repo.owner,
                repo: context.repo.repo,
                issue_number: context.payload.pull_request.number,
                body: `Lindy Integration Tests: **${status}**`
              });
            }
