Use your GHL API credentials with the specified scope (contacts.readonly). Ensure your account has the required permissions to read and manage contact data.
Configure OAuth 2.0 or an API key in the Zapier app settings to securely authorize access to the Contacts API on Squarespace Commerce.
GET /contacts/:contactId GET /contacts/:contactId/tasks GET /contacts/:contactId/tasks/:taskId GET /contacts/:contactId/notes GET /contacts/:contactId/notes/:id GET /contacts/:contactId/appointments GET /contacts/ GET /contacts/business/:businessId contacts.write POST /contacts/ PUT /contacts/:contactId DELETE /contacts/:contactId POST /contacts/:contactId/tasks PUT /contacts/:contactId/tasks/:taskId PUT /contacts/:contactId/tasks/:taskId/completed DELETE /contacts/:contactId/tasks/:taskId POST /contacts/:contactId/tags
Trigger: New or updated Squarespace contact; Action: Create or update the corresponding contact in GHL.
Actions: Create notes, set tasks, or schedule appointments in GHL linked to that contact.
POST /contacts/
email, firstName, lastName, phone
Trigger: Updated Squarespace contact; Action: Update the GHL contact using PUT /contacts/:contactId
Actions: Sync notes and tasks changes to GHL; ensure audit fields stay aligned.
PUT /contacts/:contactId
contactId, email, status
Trigger: Contact created or updated in Squarespace; Action: Add tags in GHL and attach a note.
Actions: POST /contacts/:contactId/tags and POST /contacts/:contactId/notes with summary.
POST /contacts/:contactId/tags
contactId, tags, notes
Rapid setup without writing code, using a visual workflow builder.
Seamless data synchronization between Squarespace and GHL via endpoints and events.
Scalable automation that grows with additional endpoints and apps.
Key elements include endpoints, triggers, actions, data mapping, and authorization flows that enable reliable no-code automation.
Application Programming Interface; a set of rules that lets apps like Squarespace and GHL communicate and exchange data.
A specific URL path that performs a particular action or returns data from an API.
An event in one system that starts an automated workflow in another system.
The operation performed in response to a trigger (e.g., create, update, delete).
Map Squarespace form fields to GHL contact fields to reduce manual entry and improve data consistency.
Automatically generate follow-up tasks in GHL when a new contact is added, with due dates and owners.
Append form responses as notes in the contact’s timeline for richer context.
Collect your GHL API credentials and your Zapier app credentials; prepare the required scope (contacts.readonly).
In Zapier, set up OAuth 2.0 or API key authentication and authorize access to the Contacts API.
Define field mappings, set up triggers and actions, and run end-to-end tests to verify data flows.
The GHL Contacts API supports authenticated requests using API credentials with scopes such as contacts.readonly. Ensure your API key or OAuth token is kept secure and only granted the minimum necessary permissions. Regularly rotate credentials and monitor access logs for unusual activity. In practice, you’ll configure OAuth 2.0 or an API key in your Zapier app and authorize the app to read contact data from GHL while limiting write permissions unless explicitly needed.
For Squarespace + GHL automation, start with endpoints that create, read, and update contacts (POST /contacts/, GET /contacts/:contactId, PUT /contacts/:contactId) along with tasks and notes endpoints to capture follow-ups and context (POST /contacts/:contactId/tasks, GET /contacts/:contactId/notes). These endpoints enable common workflows like syncing new form submissions to GHL and attaching contextual notes.
Yes. With no-code automation, you can map fields from Squarespace forms to GHL contact fields in Zapier, then trigger actions such as creating or updating contacts, creating tasks, or adding notes. Use field mappings and test data to ensure accuracy before going live.
Test connections in Zapier by running a sample form submission or contact update. Verify that the correct GHL contact is created or updated, and that related notes, tasks, or tags are applied as expected. Check data mappings and error logs if mismatches occur.
Rates and security depend on your API plan and OAuth configuration. Use least-privilege scopes (e.g., read-only where possible), rotate credentials, and enable secure storage. Monitor API usage to stay within quotas and guard against abuse.
While this setup targets Squarespace, the same GHL Contacts API and Zapier App Connector can connect to other apps that provide compatible endpoints. You’ll simply map the external app’s triggers to GHL actions, keeping security and data integrity in mind.
Learn more about GHL endpoints and field mappings in the official API docs and in the glossary within this guide. Use endpoint names like GET /contacts/:contactId and POST /contacts/ as references when planning data flows and field mappings.
Due to high volume, we will be upgrading our server soon!
