Canva CI Integration

Overview

Set up CI/CD pipelines for Canva Connect API integrations. Uses MSW mock server for unit tests and real API calls for integration tests.

Instructions

Step 1: GitHub Actions Workflow

# .github/workflows/canva-integration.yml
name: Canva Integration Tests

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

jobs:
  unit-tests:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - uses: actions/setup-node@v4
        with:
          node-version: '20'
          cache: 'npm'
      - run: npm ci
      - run: npm test -- --coverage
        # Unit tests use MSW mocks — no real API calls

  integration-tests:
    runs-on: ubuntu-latest
    if: github.event_name == 'push' && github.ref == 'refs/heads/main'
    needs: unit-tests
    env:
      CANVA_CLIENT_ID: ${{ secrets.CANVA_CLIENT_ID }}
      CANVA_CLIENT_SECRET: ${{ secrets.CANVA_CLIENT_SECRET }}
      CANVA_ACCESS_TOKEN: ${{ secrets.CANVA_ACCESS_TOKEN }}
    steps:
      - uses: actions/checkout@v4
      - uses: actions/setup-node@v4
        with:
          node-version: '20'
          cache: 'npm'
      - run: npm ci

      - name: Verify Canva API connectivity
        run: |
          HTTP_CODE=$(curl -s -o /dev/null -w "%{http_code}" \
            -H "Authorization: Bearer $CANVA_ACCESS_TOKEN" \
            "https://api.canva.com/rest/v1/users/me")
          if [ "$HTTP_CODE" != "200" ]; then
            echo "Canva API check failed: HTTP $HTTP_CODE"
            exit 1
          fi

      - name: Run integration tests
        run: npm run test:integration

Step 2: Configure Secrets

# Store OAuth credentials as GitHub secrets
gh secret set CANVA_CLIENT_ID --body "OCAxxxxxxxxxxxxxxxx"
gh secret set CANVA_CLIENT_SECRET --body "xxxxxxxxxxxxxxxx"

# For integration tests, store a long-lived access token
# (refresh it periodically via a separate workflow or manually)
gh secret set CANVA_ACCESS_TOKEN --body "cnvat_xxxxxxxxxxxxxxxx"

Step 3: Unit Tests with MSW Mocks

// tests/unit/designs.test.ts
import { describe, it, expect, beforeAll, afterAll } from 'vitest';
import { canvaMockServer } from '../mocks/canva-server';

beforeAll(() => canvaMockServer.listen());
afterAll(() => canvaMockServer.close());

describe('Design CRUD', () => {
  it('should create a design', async () => {
    const res = await fetch('https://api.canva.com/rest/v1/designs', {
      method: 'POST',
      headers: { 'Authorization': 'Bearer mock-token', 'Content-Type': 'application/json' },
      body: JSON.stringify({
        design_type: { type: 'custom', width: 1080, height: 1080 },
        title: 'CI Test Design',
      }),
    });
    expect(res.ok).toBe(true);
    const data = await res.json();
    expect(data.design.id).toBeDefined();
  });
});

Step 4: Integration Tests

// tests/integration/canva-api.test.ts
import { describe, it, expect } from 'vitest';

const TOKEN = process.env.CANVA_ACCESS_TOKEN;

describe.skipIf(!TOKEN)('Canva Connect API', () => {
  it('should authenticate and return user identity', async () => {
    const res = await fetch('https://api.canva.com/rest/v1/users/me', {
      headers: { 'Authorization': `Bearer ${TOKEN}` },
    });
    expect(res.status).toBe(200);
    const data = await res.json();
    expect(data.team_user.user_id).toBeDefined();
  });

  it('should list designs', async () => {
    const res = await fetch('https://api.canva.com/rest/v1/designs?limit=1', {
      headers: { 'Authorization': `Bearer ${TOKEN}` },
    });
    expect(res.status).toBe(200);
    const data = await res.json();
    expect(data.items).toBeInstanceOf(Array);
  });
});

Step 5: Token Refresh Workflow

# .github/workflows/refresh-canva-token.yml
name: Refresh Canva Token

on:
  schedule:
    - cron: '0 */3 * * *'  # Every 3 hours (tokens expire in ~4 hours)

jobs:
  refresh:
    runs-on: ubuntu-latest
    steps:
      - name: Refresh Canva access token
        run: |
          BASIC_AUTH=$(echo -n "${{ secrets.CANVA_CLIENT_ID }}:${{ secrets.CANVA_CLIENT_SECRET }}" | base64)
          RESPONSE=$(curl -s -X POST "https://api.canva.com/rest/v1/oauth/token" \
            -H "Authorization: Basic $BASIC_AUTH" \
            -H "Content-Type: application/x-www-form-urlencoded" \
            -d "grant_type=refresh_token&refresh_token=${{ secrets.CANVA_REFRESH_TOKEN }}")

          NEW_ACCESS=$(echo "$RESPONSE" | jq -r '.access_token')
          NEW_REFRESH=$(echo "$RESPONSE" | jq -r '.refresh_token')

          if [ "$NEW_ACCESS" != "null" ]; then
            gh secret set CANVA_ACCESS_TOKEN --body "$NEW_ACCESS"
            gh secret set CANVA_REFRESH_TOKEN --body "$NEW_REFRESH"
            echo "Token refreshed successfully"
          else
            echo "Token refresh failed: $RESPONSE"
            exit 1
          fi
        env:
          GH_TOKEN: ${{ secrets.GITHUB_TOKEN }}
