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}**`
              });
            }

Test Categories

Category	What It Tests	Requires Live Lindy?
Auth verification	Webhook signature checking	No
Payload processing	Data extraction and transformation	No
Error handling	Malformed input, edge cases	No
Connectivity	Webhook endpoint reachability	Yes (non-blocking)
End-to-end	Full trigger -> callback cycle	Yes

Error Handling

Issue	Cause	Solution
Secret not found in CI	Not configured	gh secret set LINDY_WEBHOOK_SECRET
Connectivity test fails	Lindy endpoint unreachable in CI	Mark as continue-on-error: true
Tests timeout	Network latency	Set timeout-minutes: 10 on job
Flaky live tests	Lindy processing delay	Add retry logic or mock external calls

Output

Produce a CI integration record containing the workflow trigger, test fixtures, required secrets by name only, failure ownership, and the command or dashboard evidence proving that the automation ran against a non-production agent.

Examples

For a pull request, trigger a disposable Lindy test agent with fixed fixture input, wait for its terminal status, and fail the workflow when the expected action is absent or the agent reports an error. Keep the production agent ID out of the workflow and promote only after the fixture result is reviewed.
