5. Click **Continue** — Zapier tests the connection against a recent booking.

| Step 3: Add an action

Choose what happens next with your booking data:

* **Email marketing:** add attendees to Mailchimp or ActiveCampaign.
* **Spreadsheets:** log bookings in Google Sheets or Airtable.
* **Team chat:** post to Slack or Microsoft Teams.
* **CRM:** update HubSpot, Pipedrive, or Zoho CRM.

Click **Publish** to make your Zap live.

| Troubleshooting

* **Key not working?** Check for an accidental extra space at the start or end of the API key.
* **Team events:** make sure you generated the key for that **Team**, not just your personal account.
