What data can I sync between Sleekplan and the Contacts API?

Sleekplan can sync contact fields, notes, tasks, and tags with the GHL Contacts data. You can map standard fields like name, email, phone, and custom fields to ensure data consistency. For real-time updates, set up triggers that push changes as soon as they occur. You can also schedule periodic syncs if needed.

No-code setup is possible using our visual workflow builder. You can authorize the connection, select endpoints, and define triggers and actions without writing code. For advanced scenarios, you may add custom mappings or use webhooks if available.

Supported read endpoints include GET /contacts/:contactId, GET /contacts/:contactId/tasks, GET /contacts/:contactId/notes, GET /contacts/:contactId/appointments. Write operations include POST /contacts/, PUT /contacts/:contactId, POST /contacts/:contactId/tasks, and POST /contacts/:contactId/tags. Some endpoints require appropriate scopes and permissions.

Authenticate via OAuth 2.0 or API keys from the connected apps. Exchange credentials for access tokens with the contacts.readonly scope, then attach the token to requests. Regularly rotate credentials and monitor for unauthorized access.

Yes. Triggers can push updates to GHL in real-time or near-real-time. Use webhooks or polling depending on your plan and needs. Set up event-driven actions to automate workflows across Sleekplan and GHL.

If a contact is deleted in GHL, Sleekplan can be configured to archive or remove the corresponding contact in Sleekplan or to retain the record with a soft delete, depending on your workflow. Consider data retention policies.
