Authenticate via the GHL OAuth flow to obtain an access token that grants the necessary scope (contacts.readonly) for reading and syncing contact data with Sellsy.
Configure your Sellsy app in GHL, register the redirect URI, and complete the OAuth exchange to securely connect Sellsy to 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 – GET /contacts/:contactId – 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: when a contact is created or updated in Sellsy, push changes to the GHL Contacts data to keep both systems in sync.
Actions: create or update contact, attach notes, and schedule related tasks when changes occur in Sellsy.
Method example: GET /contacts/:contactId to fetch a contact; POST /contacts/ to create a contact.
Key fields: contactId, name, email, phone, company
Trigger: a new or updated task in either system triggers an update in the other.
Method: POST /contacts/:contactId/tasks; or PUT /contacts/:contactId/tasks/:taskId to modify.
Key fields: taskId, status, dueDate, description
Trigger: notes added or updated in one app propagate to the other.
Method: GET /contacts/:contactId/notes; POST /contacts/:contactId/notes
Key fields: noteId, noteContent, createdAt
Automate data flow between Sellsy and the Contacts API without writing code.
Use visual mappings and triggers to set up workflows quickly.
Deploy reusable templates and endpoints for scalable integrations.
Understand core elements, processes, and how data maps between Sellsy and the GHL Contacts API.
A person or organization stored in both systems, identified by contactId and essential fields.
A specific URL path and HTTP method used to perform an action in the API.
An authorization protocol used to obtain access tokens for secure API calls.
A callback URL that notifies you of events like updates or creations.
Automatically create and update contact records across systems when changes occur.
Trigger task templates when specific contact events happen to streamline follow-ups.
Consolidate notes from both apps into a single, searchable notes feed.
Register your app in GHL, obtain client credentials, and set the redirect URI for OAuth.
Define how Sellsy fields map to Contacts API fields to enable accurate sync.
Run tests, set up monitoring, and deploy to production with confidence.
Use OAuth 2.0 with refresh tokens to securely authorize. The integration flow guides you through obtaining an access token that grants read access to contacts and related items. Ensure your app permissions align with the scope: contacts.readonly. You can refresh tokens as needed to maintain access without re-authenticating.
The endpoints include retrieving contacts, tasks, notes, and related data. You can read contact data and associated items, create new records, and update existing ones as needed for synchronization.
No code is required if you use the built-in connector or visual workflow builders. You can configure field mappings, triggers, and actions without writing custom code.
Use the field-mapping features to align Sellsy fields with corresponding GHL Contacts fields. Start with essential mappings (name, email, phone) and expand to notes and tasks as your workflow grows.
Test in a sandbox or with a small subset of data. Validate that creates, updates, and deletions sync as expected before going live.
Be aware of API rate limits and implement exponential backoff retries. Monitor logs to identify failed calls and adjust polling intervals accordingly.
Endpoint examples are shown in the Endpoints list above. For troubleshooting, review API responses, authentication status, and event logs in your GHL and Sellsy apps.
Due to high volume, we will be upgrading our server soon!
