​
Local Testing Workflow

  1. Start the local webhook receiver: 
    asc webhooks serve --port 8787 --dir ./webhook-events
  2. Use a tunnel service (ngrok, Cloudflare Tunnel) to expose the local server: 
    ngrok http 8787
  3. Create a webhook in App Store Connect pointing to the tunnel URL: 
    asc webhooks create \
  --app "APP_ID" \
  --name "Test Webhook" \
  --url "https://abc123.ngrok.io" \
  --secret "test-secret" \
  --events "SUBSCRIPTION.CREATED" \
  --enabled true
  4. Trigger events in App Store Connect and watch the local receiver log incoming events
  5. Clean up: 
    asc webhooks delete --webhook-id "WEBHOOK_ID" --confirm
