Access the Contacts API with a secure token or API key. Use the appropriate scope (e.g., contacts.readonly for read-only workflows) and keep credentials secure.
Connect Formstack to GHL via OAuth 2.0 or an API key, then authorize the Contacts API connection and grant necessary permissions for form-derived data.

No coding required to capture Formstack submissions in your CRM.
Automate lead routing and contact updates in real-time.
Fast setup with minimal maintenance and built-in data mapping.
This glossary defines API endpoints, authentication, field mapping, and data workflows used in the GHL Contacts API, Formstack, and the App Connector.
A specific URL path used to perform an operation on the GHL Contacts API, such as retrieving a contact.
The method to prove identity to the API, typically OAuth 2.0 or API keys, with the correct scopes.
A person in your CRM with linked data fields like email, name, phone, and company.
A callback URL that Formstack can POST data to when events occur in the integration.
Automatically create a contact in Contacts API when Formstack submissions occur, eliminating manual entry.
Create tasks in Contacts API triggered by form fields such as deadline and owner.
Attach form responses as notes on the contact to preserve context.
Set up OAuth or API key exchange between Formstack and the Contacts API, then select the Contacts API scope.
Map Formstack fields to Contacts API fields like email, name, and notes.
Run end-to-end tests, verify data flow, and monitor for errors before going live.
The GHL Contacts API supports OAuth 2.0 or API key-based authentication. Choose the method supported by your environment and grant the app the necessary scope (e.g., contacts.readonly for read-only workflows). The authentication flow validates your access before any data is exchanged. Keep credentials secure and rotate keys regularly.
Map common fields such as email, first_name, last_name, and phone to the corresponding Contacts API fields. Use Formstack’s field mappings to ensure data integrity and avoid duplicates. For custom fields, map them to the API’s custom fields and rely on a unique identifier like email for deduplication.
Yes. You can create a new contact or update an existing one from a Formstack submission by posting to /contacts/ or putting to /contacts/:contactId. Use a deduplication strategy (typically by email) to determine whether to create or update.
Most endpoints are accessible according to your granted scopes. If you use a read-only configuration, only GET endpoints will be available. For write-enabled flows, ensure the app connection has the appropriate write scopes.
Use Formstack’s test submissions and the API connector’s test tools. Validate data mapping, triggers, and error handling, then review logs and retry policies to ensure reliability.
If a contact already exists, the integration can update the existing record based on a unique key like email. Implement dedup logic to prevent duplicates and preserve data history.
Logs are available in the App Connector dashboard and Formstack’s workflow history. Look for error messages, check request payloads, and retry failed operations.
Due to high volume, we will be upgrading our server soon!
