Access to the Contacts API is secured with OAuth scopes such as contacts.readonly. Use your GHL API credentials and grant LeadDelta the necessary permissions to read and manage contacts, tasks, notes, and appointments.
In LeadDelta, configure the Zapier connection to request the Contacts API scopes and ensure the app is authorized to create, read, update, and delete contact data as needed.
Key endpoints you’ll use 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; 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: A contact is created or updated in LeadDelta.
Actions: Create or update the corresponding GHL contact via POST /contacts/ or PUT /contacts/:contactId, then set key properties and attach tags as needed.
POST /contacts/ and PUT /contacts/:contactId
Key fields: email, firstName, lastName, phone, leadDeltaId, tags, custom fields
Trigger: A LeadDelta task is updated.
Actions: Update the GHL task via PUT /contacts/:contactId/tasks/:taskId to reflect status or due date.
PUT /contacts/:contactId/tasks/:taskId
Key fields: contactId, taskId, status, dueDate
Trigger: A new note is added in LeadDelta.
Actions: POST /contacts/:contactId/notes with note content and metadata.
POST /contacts/:contactId/notes
Key fields: contactId, noteId, content, createdAt
Automate data sync between LeadDelta and GHL without writing code, saving time and reducing errors.
Create powerful triggers and actions to build custom workflows across platforms.
Gain a unified view of contact data, notes, and tasks across LeadDelta and GHL.
Understand the core elements: endpoints define access points, triggers start automations, actions perform tasks, and authentication secures access.
A specific URL combined with an HTTP method used to interact with the API (for example, GET /contacts/:contactId).
An event that starts an automation, such as a new contact being created in LeadDelta.
An operation performed in response to a trigger, such as creating or updating a GHL contact.
The process of verifying identity to access the API, typically via OAuth or API keys.
Automatically propagate new LeadDelta contacts to GHL with minimal delay.
Trigger different GHL actions when a LeadDelta contact earns a tag or a custom field value.
Consolidate notes, tasks and contact updates from LeadDelta and GHL into one view.
Obtain API credentials, authorize LeadDelta, and ensure the correct scopes are granted (contacts.readonly and more).
Map LeadDelta fields to GHL contact fields such as email, name, phone, notes, and tags to ensure data fidelity.
Run integration tests, monitor logs, fix errors, and deploy to production.
No coding is required—this is a no-code integration built with Zapier-style automation. Start by connecting both accounts, map your key fields, and enable a test run to verify data flows. If you run into issues, check endpoint permissions and scopes, then re-authenticate the connection. You can usually resolve most problems by refreshing tokens and validating field mappings.
You can sync core contact data (name, email, phone), notes, tasks, and custom fields between LeadDelta and GHL. Configure which fields flow in each direction and set up triggers for updates or new entries to keep both systems aligned.
Security is enforced via OAuth tokens and scoped access. Ensure credentials are stored securely, and limit scopes to what is necessary. LeadDelta app connections also support audit logs for traceability.
Yes. Map fields flexibly in the connector settings. You can rename fields, combine values, and handle defaults to maintain data integrity across systems.
API usage depends on your plan and the endpoints used. Leverage bulk operations where available and monitor rate limits. If you hit a limit, stagger requests or upgrade your plan.
Check recent activity and error messages in the integration logs. Verify credentials, scopes, and endpoint paths. Re-run failed steps with test data and consider adding retry logic for transient issues.
Yes—depending on the endpoint and event, you can enable near-real-time syncing via webhooks or frequent polling. Use throttling and robust error handling to maintain stability.
Due to high volume, we will be upgrading our server soon!
