# Marketing campaigns not auto-populating when using Zapier integration

## Problem

Marketing campaigns were not auto-populating in Zapier when creating a zap for Google form fills and Facebook Lead Ads. The campaigns would appear initially but stop populating after filling out other fields in the zap.

## Solution

### Workflow Summary

Delete your current zap and create a new one. Fill out the campaign field first before other fields.

### Delete current zap

1. Delete your current zap completely.
2. Create a new zap from scratch using the **Create Booking** action.
3. Connect to ServiceTitan and verify the connection is active.
4. Fill out the **Campaign** field first before completing other fields.
5. Select your marketing campaign from the auto-populated list.
6. Complete the remaining required fields in this order:
  1. Name
  2. Address
  3. Summary
  4. External ID (use a unique identifier from your form)
7. Test the zap to confirm it works properly.
8. Clear your [browser cache](/construction/docs/servicetitan-tips-and-tricks#clearing-your-cache) to prevent future issues.

### Instructions for Source field

1. Go to **Settings** in the top toolbar.
2. In the side panel, go to **Integrations > Booking Providers.**
3. Create your *Booking Provider* ID first.
4. Manually type your source name in the *Source* field in Zapier.
5. The Source field will not auto-populate and requires manual entry.
