To access the GHL Contacts API, obtain an access token with the defined scope (contacts.readonly). Store and refresh the token securely and send it with each request.
LeadDyno authenticates to GHL using the app’s OAuth credentials. Use the client ID and client secret, request the required scope, and exchange tokens securely.
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: When a contact is created or updated in LeadDyno, push changes to GHL via POST /contacts/ or PUT /contacts/:contactId.
Actions: create or update contact, update tasks, attach notes, and apply tags or custom fields.
Method path examples: POST /contacts/ for new contacts; PUT /contacts/:contactId for updates; DELETE when removing records.
Key fields: contactId, email, firstName, lastName, phone, tags, status
Trigger: Task creation or note addition in LeadDyno should reflect in GHL and vice versa.
Actions: create/update tasks via POST /contacts/:contactId/tasks and notes via POST /contacts/:contactId/notes; update task status with PUT /contacts/:contactId/tasks/:taskId and completed state.
Method path examples: POST /contacts/:contactId/tasks, POST /contacts/:contactId/notes, PUT /contacts/:contactId/tasks/:taskId, PUT /contacts/:contactId/tasks/:taskId/completed
Key fields: contactId, taskId, title, status, dueDate, notes
Trigger: Tag changes in LeadDyno should be reflected in GHL for segmentation.
Actions: add/remove tags via POST /contacts/:contactId/tags and update custom fields to drive campaigns.
Method path: POST /contacts/:contactId/tags
Key fields: contactId, tags
No-code automation lets you sync contacts, tasks, notes, and tags without writing code, using triggers and actions in your integration workflow.
Quickly deploy workflows with familiar LeadDyno patterns, reusing existing campaigns and sequences.
Centralized data in GHL makes reporting, segmentation, and support handoffs faster for your team.
Key elements and processes explained below to help you implement the integration effectively.
Application Programming Interface: a set of endpoints and protocols that enable apps to communicate.
OAuth 2.0 is an authorization framework that grants tokens to call APIs securely.
A specific URL in an API that performs a defined action, typically accessed with HTTP methods.
Permissions granted to an access token that determine which actions are allowed.
Configure a webhook in GHL to push contact updates to LeadDyno as they happen, and reflect changes back to GHL.
Use tags and custom fields to create lifecycle-based segments and trigger targeted LeadDyno campaigns.
Automatically generate and update GHL tasks from LeadDyno milestones to keep teams aligned.
Collect your GHL API client details and LeadDyno app credentials; ensure the scope is set to contacts.readonly.
Map the necessary endpoints (such as /contacts and /contacts/:contactId/tasks) and request the correct scope.
Run tests, verify data synchronization, and set up alerts for failed requests.
No heavy coding is required for most common use cases. The integration can be configured with no-code automation tools like Zapier, using triggers and actions to sync data between LeadDyno and the GHL Contacts API. For advanced needs, you can map additional fields and add conditional logic to handle edge cases.
For basic contact sync, you’ll typically interact with endpoints such as GET /contacts/:contactId, POST /contacts/, PUT /contacts/:contactId, and relevant sub-resources for tasks and notes. Map the fields you need (email, name, phone) and keep IDs consistent across systems.
Authentication relies on OAuth tokens with a defined scope. Store tokens securely and implement a refresh strategy to maintain access without downtime. Rotate credentials as needed and monitor for token expiry events.
Yes. You can create and update tasks via POST /contacts/:contactId/tasks and attach notes via POST /contacts/:contactId/notes. You can also update task status with PUT /contacts/:contactId/tasks/:taskId and mark completed with PUT /contacts/:contactId/tasks/:taskId/completed.
No-code options let you implement typical use cases quickly using triggers, filters, and actions. If you run into limits, you can add custom mappings or switch to a lightweight code step.
By default, core fields like name, email, phone, and basic tags are synced. You can extend with custom fields in both LeadDyno and GHL if you need richer profile data.
Refer to the GHL developer docs and the Zapier app connector docs for endpoint references, parameters, and example payloads. The endpoint list above provides a quick reference.
Due to high volume, we will be upgrading our server soon!
