Authenticate to the GHL Contacts API by obtaining a valid API token from your GHL developer settings and including it in the Authorization header (scope: contacts.readonly).
Secure your connection to Mightycause by generating an API key or OAuth token in the Mightycause developer portal and using it in Zapier to authorize requests.

Trigger: a new or updated contact is added in Mightycause to sync with GHL Contacts
Actions: create or update a GHL contact; optionally map and attach related tasks or notes.
Endpoints used: POST /contacts/ to create; PUT /contacts/:contactId to update
Key fields: external_id, name, email, phone
Trigger: a Mightycause task is created or updated to mirror in GHL
Actions: create/update tasks in GHL via POST /contacts/:contactId/tasks and PUT /contacts/:contactId/tasks/:taskId; mark completed with PUT /contacts/:contactId/tasks/:taskId/completed
Endpoints: POST /contacts/:contactId/tasks; PUT /contacts/:contactId/tasks/:taskId; PUT /contacts/:contactId/tasks/:taskId/completed
Key fields: taskId, contactId, title, status, dueDate
Trigger: a note is added in Mightycause to attach to a GHL contact
Actions: create notes in GHL with POST /contacts/:contactId/notes and retrieve with GET /contacts/:contactId/notes/:id
Endpoints: POST /contacts/:contactId/notes; GET /contacts/:contactId/notes/:id
Key fields: noteId, contactId, title, content, date
Automate donor data, tasks, and notes without writing code
Keep CRMs and fundraising apps in sync for faster outreach
Custom workflows you can deploy in minutes with Visual Zapier steps
Core elements include API endpoints, authentication, webhooks, and field mapping; processes cover triggers, actions, and testing
A programmatic interface that allows apps to talk to each other and exchange data.
Verifying identity and granting access to API resources, typically via API keys or OAuth tokens.
A specific URL path that performs an action in an API.
A real-time notification sent by an app when an event occurs.
Set up an automation to add or update a GHL contact whenever a new supporter is added in Mightycause; keep donor records consistent.
Create follow-up tasks in GHL when actions occur in Mightycause to ensure timely outreach.
Attach Mightycause notes to corresponding GHL contacts to keep notes in sync.
Generate API credentials in both platforms and add them to Zapier connections.
Choose triggers in Mightycause and map them to Actions in GHL.
Ensure field mappings align and run test flows to verify data sync.
No coding is required. This setup uses Zapier to connect GHL’s Contacts API with Mightycause via pre-built triggers and actions. You can configure mappings in a visual editor. If you need advanced logic, consider a low-code approach with conditional steps.
You can sync essential donor details like name, email, and donor notes; and you can also sync tasks and tags tied to contacts. Some data types may require custom fields.
Connections use encryption in transit (TLS) and stored API keys or OAuth tokens. Rotate credentials regularly and monitor access.
Yes. Use Zapier field mapping, multi-step Zaps, and custom fields to control which data moves between GHL and Mightycause.
Use Zapier’s test flow and the built-in data picker to verify mappings; run real-world tests with sample records and check for errors in the task history.
Yes, there are rate limits on both sides; design your Zaps to batch updates or stagger calls to stay within limits.
API docs for both endpoints live in the GHL and Mightycause developer portals; look for the Contacts API docs and Mightycause API docs for endpoints and field reference.
Due to high volume, we will be upgrading our server soon!
