To call the Contacts API, obtain an access token from GHL and include it in the Authorization header for each request.
Register SMSPLANET in your GHL developer console, generate an API key with the contacts.readonly scope, and keep credentials secure.
Endpoints covered include: 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: GET /contacts/:contactId to pull a contact and its tasks into SMSPLANET workflows.
Actions: Retrieve contact data, fetch related tasks, and update task statuses as needed.
GET /contacts/:contactId
Key fields: contactId, firstName, lastName, email
Trigger: GET /contacts/:contactId/notes and GET /contacts/:contactId/appointments to keep records up to date.
Actions: Create, update, or delete notes; create or reschedule appointments.
GET /contacts/:contactId/notes
Key fields: noteId, contactId, content, dueDate
Trigger: POST /contacts/:contactId/tags to assign tags based on activity.
POST /contacts/:contactId/tags
Key fields: contactId, tagData
No-code automation: trigger workflows by changes to contacts, notes, or tasks without writing any code.
Real-time data sync across SMSPLANET and GHL for consistent records.
Centralized API access with scalable endpoints for teams and workflows.
Key elements include API endpoints, authentication, rate limits, data mappings, and error handling to ensure reliable integration.
Application Programming Interface: a set of rules that lets apps talk to each other and exchange data securely.
A standard protocol for obtaining access tokens to authorize API calls.
A specific URL where an API call can be made to perform a function.
A callback URL that notifies your app when an event occurs in the API.
When a new lead is captured in SMSPLANET, automatically create or update the corresponding contact in Contacts API to keep data in sync.
Create tasks in GHL when a follow-up is due in SMSPLANET, and pull status updates back to SMSPLANET.
Tag contacts automatically based on engagement history and campaign responses to streamline targeting.
Obtain your GHL API key and set scope to contacts.readonly for read access.
Add endpoints such as GET /contacts/:contactId and GET /contacts/:contactId/tasks to your app’s workflow.
Test in sandbox, validate data mappings, then go live with your SMSPLANET integration.
You can read core contact fields such as name, email, phone, and associated relationships like tasks, notes, and appointments. The API also supports reading business associations when provided in the endpoint scope. You’ll pull data exactly as the GHL data model exposes it. \n\nUse GET calls to retrieve data and map it into SMSPLANET workflows for up-to-date records.
Authenticate requests with an access token issued by GHL. Include the token in the Authorization header as Bearer
The most useful endpoints for SMSPLANET are GET /contacts/:contactId, GET /contacts/:contactId/tasks, GET /contacts/:contactId/notes, GET /contacts/:contactId/appointments, and POST /contacts/:contactId/tags. Other endpoints support creation and updates as needed.
Yes. You can update core contact data with PUT /contacts/:contactId, modify tasks with PUT /contacts/:contactId/tasks/:taskId, and manage notes with PUT /contacts/:contactId/notes/:id. Tags can be added or removed via POST /contacts/:contactId/tags.
No-code options exist: use automation tools to connect endpoints and trigger workflows without writing code. You can also leverage prebuilt Zapier-like setups to sync data between GHL and SMSPLANET.
Rate limits depend on your plan and API usage. Start with the default sandbox limits and implement retry with exponential backoff. If you exceed limits, wait and retry later to avoid failures.
Test with a sandbox or staging environment, validate each mapping, and verify that data updates propagate to SMSPLANET. Use sample contacts to mimic real scenarios before going live.
Due to high volume, we will be upgrading our server soon!
