To access the Contacts API, obtain an API key or OAuth token with a scope that includes at least contacts.readonly. Store credentials securely and rotate them regularly. Use standard OAuth 2.0 flows or API keys as supported by your GHL account.
Sierra Interactive acts as the client in the OAuth flow. In your app settings, register the GHL Contacts API and exchange tokens. Use the token to authorize API calls and map the necessary scopes for reading contact data.
Core endpoints include retrieving, creating, updating, and deleting contacts; managing tasks, notes, appointments, and tags. Use GET for reads, POST for creates, PUT for updates, and DELETE for removals. Field mapping between GHL and Sierra Interactive ensures data sync across contacts, tasks, notes, and tags.
Trigger: when a contact is created or updated in Sierra Interactive, pull the latest data from GHL.
Actions: upsert contact in Sierra, including name, email, phone; refresh related tasks and notes.
GET /contacts/:contactId
contactId, email, firstName, lastName, phone, status
Trigger: when a contact gains a new task or note in GHL or Sierra, sync across systems.
Actions: create/update tasks, notes, and appointments in Sierra Interactive based on GHL events.
GET /contacts/:contactId/tasks
contactId, taskId, dueDate, status
Trigger: when a tag is added in GHL or Sierra
Actions: post /contacts/:contactId/tags to Sierra to enrich contact records.
POST /contacts/:contactId/tags
contactId, tag
Automate data flow without custom development — set up triggers and actions with clicks.
Keep your contact records in sync across systems to reduce manual data entry.
Improve visibility with centralized notes, tasks, and appointments in Sierra Interactive.
This glossary covers terms and processes used in GHL Contacts API integration with Sierra Interactive, including endpoints, triggers, and data mapping.
A person in your database with contact details, notes, tasks, and history.
A specific URL in the GHL API used to perform an action (GET, POST, PUT, DELETE) on contacts data.
An authorization framework that enables secure access to the GHL API without sharing credentials.
A callback URL that GHL calls to notify Sierra Interactive of changes.
Set up a trigger when a new lead is created in Sierra Interactive to create or update a corresponding contact in GHL, ensuring no duplicate records.
Push GHL activities (calls, notes, tasks) into Sierra as notes or tasks to keep a complete history in one place.
Automatically tag Sierra contacts when specific GHL tags are added, enabling targeted automations and lists.
In GHL, generate API credentials or OAuth client details and share with Sierra Interactive. Configure scopes to include contacts.readonly for safe access.
Within Sierra Interactive, map GHL contact fields (id, name, email, phone) to Sierra fields and configure endpoint paths for reads and writes.
Run test synchronizations, verify data parity, and enable logging and alerts to monitor for errors or rate limits.
No advanced coding is required. Use the built-in connectors and point-and-click mapping in Sierra Interactive. The API endpoints handle the heavy lifting for data retrieval and updates. If you have developers, you can extend with custom webhooks or scripts for advanced flows.
Read-only scope allows access to contact data, tasks, notes, and appointments. Write endpoints require write permissions. If you need additional access, request higher scope from your GHL admin and adjust your integration accordingly.
Authentication uses OAuth 2.0 or API keys. Obtain tokens and refresh as needed, then store credentials securely and rotate them periodically. Ensure each API call includes a valid access token.
Yes. You can map write actions to update or create records in GHL from Sierra Interactive, using endpoints like POST /contacts/:contactId or PUT /contacts/:contactId. Ensure scopes allow writes and implement deduplication logic.
Real-time syncing is possible with webhooks, depending on your plan and configuration. You can also schedule regular polls if webhooks are not available in your setup.
We provide mapping templates and example payloads in the docs. You can customize field mappings, triggers, and endpoint usage to fit your workflow.
Due to high volume, we will be upgrading our server soon!
