Use your GHL API key with the defined scope (contacts.readonly). Include the key in the Authorization header for every request.
SleekFlow authenticates via the GHL API key and passes it in requests to the Contacts API; keep keys secure and rotate regularly.
Core endpoints used in this integration include: GET /contacts/:contactId, GET /contacts/, POST /contacts/, PUT /contacts/:contactId, DELETE /contacts/:contactId, GET /contacts/:contactId/tasks, GET /contacts/:contactId/notes, GET /contacts/:contactId/appointments, POST /contacts/:contactId/tasks, PUT /contacts/:contactId/tasks/:taskId, PUT /contacts/:contactId/tasks/:taskId/completed, DELETE /contacts/:contactId/tasks/:taskId, GET /contacts/business/:businessId
Trigger: Retrieve contact details to sync profile data in SleekFlow when a contact is created or updated in GHL.
Actions: GET /contacts/:contactId, map fields to SleekFlow, and push to workflows.
GET /contacts/:contactId
id, email, firstName, lastName, phone, customFields
Trigger: Periodic sync to ensure SleekFlow reflects the latest GHL contacts.
Actions: GET /contacts/, iterate results, create or update SleekFlow contacts.
GET /contacts/
id, email, name, phone, company, status
Trigger: When a GHL contact updates, push the changes to SleekFlow.
Actions: PUT /contacts/:contactId, update fields in SleekFlow, trigger automations.
PUT /contacts/:contactId
id, updatedFields
No custom development required to sync data between GHL and SleekFlow.
Real-time updates keep teams aligned across CRMs and automation workflows.
Secure, scalable data flow with role-based access and audit trails.
A quick glossary of terms used in this integration: endpoints, methods, triggers, actions, and fields.
Application Programming Interface: a set of rules that allows SleekFlow to request data from GHL’s Contacts API.
A specific URL that performs a defined function in the API.
A secure framework for authorizing access to resources without sharing user credentials.
A URL that GHL can call to notify SleekFlow of events in real time.
Capture new leads from GHL and auto-create corresponding contacts in SleekFlow to trigger nurture flows.
Whenever a task or note is updated in GHL, reflect it in SleekFlow to keep teams aligned.
Use GHL contact properties to segment and personalize SleekFlow campaigns.
Obtain your GHL API key, set scope to contacts.readonly, and ensure you have permissions to read contact data.
Map GHL endpoints to SleekFlow fields and verify response formats.
Run tests in a staging environment, check logs, then enable in production.
No-code options are available. Use the built-in connectors and endpoint mappings to set up data flow between GHL and SleekFlow. If you prefer, you can script minimal automations using standard HTTP actions. The goal is to enable real-time or scheduled sync without writing a full integration service. For most teams, the visual setup is sufficient to start collecting and routing contact data. You can extend functionality later as needed.
Start with core endpoints like GET /contacts/:contactId to fetch individual records and GET /contacts/ to fetch lists. Map key fields (id, email, name, phone) to SleekFlow contact fields. Validate updates with PUT /contacts/:contactId. As you scale, add notes, tasks, and tags endpoints to enrich profiles.
Authentication uses your GHL API key, included in the Authorization header for each request. Use the scope that matches your needs (e.g., contacts.readonly for read operations). Rotate keys regularly and follow best practices for credential storage. SleekFlow will pass the API key to GHL on every call.
You can access contact basics (id, name, email, phone), custom fields, tasks, notes, and appointments. Access is governed by the API key scope and your GHL permissions. If you need additional fields, map them in the endpoint responses to SleekFlow fields.
Rate limits depend on your GHL plan. Plan for bursts during initial sync and implement backoff and retry logic. Monitor API usage via your GHL dashboard and SleekFlow logs to optimize requests.
Due to high volume, we will be upgrading our server soon!
