The Contacts API uses OAuth 2.0 and token-based authentication. Your current scope is readonly (contacts.readonly); to perform edits you must switch to contacts.write and configure secure credential handling.
In Fourthwall, store credentials securely, rotate keys regularly, and use a secrets vault to protect tokens used for the Contacts API.
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 contact created in Contacts API; Action: push data to Fourthwall and create or update a corresponding contact.
Actions: fetch core fields, map to Fourthwall schema, and log the sync.
GET /contacts/:contactId
Key fields: id, name, email, phone
Trigger: contact updated in Contacts API
Actions: fetch updated fields and push to Fourthwall to keep records synchronized
PUT /contacts/:contactId
Key fields: id, lastModified
Trigger: bulk export from Contacts API; Action: seed Fourthwall with new records in batches
Actions: batch create, map fields, verify integrity, and report results
POST /contacts/
Key fields: id, createdAt
Faster automation: connect data without writing code
Easier data governance with centralized workflows
Scalable integration as your business grows
Elements to understand: endpoints, triggers, actions, method paths, and fields used for mapping data between Contacts API and Fourthwall.
An individual URL path that performs a specific action or retrieves data from the API.
An event that starts an automation or workflow between apps.
An operation performed in response to a trigger, creating or updating data.
The process of aligning data fields between systems.
Pull contact data from Contacts API and enrich Fourthwall records for richer analytics.
Automatically create tasks in Contacts API from events in Fourthwall and track progress.
Seed new leads into both systems with a guided onboarding flow.
Register your app in the GHL developer console and obtain client credentials for OAuth 2.0.
Set the scope to contacts.readonly (or contacts.write for write access) and map endpoints to Fourthwall fields.
Run test requests, verify mapping, and enable live syncing between the systems.
If you need to edit data or create new records, enable the write scope (contacts.write). For read-only use, you can still view contacts and related data with the contacts.readonly scope. Ensure you rotate credentials regularly.
Authenticate via OAuth 2.0 using client credentials, and include the access token in your requests. For basic scripts, an API key may be used if supported, stored securely.
Sync requires endpoints for retrieving contacts and updating fields. At minimum, use GET /contacts/:contactId and PUT /contacts/:contactId to keep data aligned.
Yes, use POST /contacts/ to create records in both systems, then map fields and verify audit trails.
Respect rate limits by batching requests, implementing exponential backoff, and caching repeated calls.
If the connection drops, retry with backoff, log errors, and alert your team. Ensure you have a fallback plan.
Store keys in a secrets manager or secure vault and rotate them periodically.
Due to high volume, we will be upgrading our server soon!
