Access to the Contacts API is controlled via a scoped API token. Use the provided credentials to request read-only access (scope: contacts.readonly) or expand permissions as needed for write operations.
Configure the same credentials in ticket-io to authorize requests to the Contacts API. Follow the OAuth2 or API key flow your setup requires.
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 contacts.write 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 viewed or updated in GHL, fetch the latest tasks and notes via GET endpoints.
Actions: Retrieve contact data, pull related tasks and notes, and push updates to ticket-io workflows.
Methods used: GET /contacts/:contactId and GET /contacts/:contactId/tasks to populate ticket-io tickets.
Key fields: contactId, taskId, status, dueDate
Trigger: A new ticket is created in ticket-io, which creates a corresponding task in Contacts API.
Actions: POST /contacts/:contactId/tasks to create tasks; update status as tickets progress.
Methods: POST /contacts/:contactId/tasks; PUT /contacts/:contactId/tasks/:taskId to update.
Key fields: contactId, taskId, title, status, dueDate
Trigger: Changes to contact notes or tags in GHL trigger corresponding notes in Contacts API.
Actions: POST /contacts/:contactId/notes to store notes; POST /contacts/:contactId/tags to assign tags.
Methods: POST /contacts/:contactId/notes; POST /contacts/:contactId/tags; GET /contacts/:contactId/notes for history.
Key fields: contactId, noteId, tagName
No-code automation: Build workflows visually without writing code.
Real-time data syncing between your Contacts and ticket data.
Faster onboarding and scalable processes for teams.
Here are essential elements and processes used to build a ticket-io to Contacts API integration: endpoints, authentication, triggers, actions, field mapping, and data validation.
GHL refers to the API ecosystem powering the Contacts API and app connectors within the platform.
An endpoint is a URL path that exposes a resource or action in the API (e.g., GET /contacts/:contactId).
OAuth is a standard authorization protocol used to grant apps access to the API on behalf of a user.
A task is a unit of work associated with a contact, such as a follow-up, note, or reminder.
When a new ticket is created in ticket-io, automatically create or update the corresponding contact in the Contacts API and attach related tasks.
Sync notes from Contacts API to ticket-io to keep context across teams and improve collaboration.
Auto-update tasks in Contacts API as ticket statuses change, keeping data in sync.
Obtain API credentials and configure in ticket-io to authorize requests to the Contacts API.
Choose the required endpoints and set the appropriate scope (for example, contacts.readonly for read access).
Create a basic workflow in ticket-io that reads contact data and creates tasks to demonstrate data flow.
The Contacts API supports scoped access. For read-only integrations, use the scope: contacts.readonly. If you need to create or modify records, request additional permissions via your app’s developer settings. Always test scopes in a sandbox or staging environment before going live. Follow the principle of least privilege to minimize risk and simplify maintenance.
No-code approaches let you build and test integrations visually using triggers, actions, and field mappings. You can connect ticket-io to the Contacts API without writing code by using prebuilt connectors or workflow builders. If your scenario requires custom logic, you can add lightweight scripting or webhooks to extend capabilities.
Common read endpoints include GET /contacts/:contactId and GET /contacts/:contactId/tasks to fetch data. Write endpoints such as POST /contacts/, PUT /contacts/:contactId, and DELETE /contacts/:contactId enable creating, updating, or removing records. Always consult the endpoint list to confirm available operations and required permissions.
Authenticate using OAuth2 or API keys as configured in your app settings. Securely store credentials and rotate them periodically. Use your developer portal to manage scopes and client IDs. Test authentication flows in a development environment before enabling production access.
Yes, you can achieve near real-time sync by using webhooks or scheduled polling, depending on your setup. Configure triggers to listen for changes in either system and push updates accordingly. Keep data latency in mind and design idempotent workflows to handle retries gracefully.
Field mapping is about aligning data types and identifiers between systems (e.g., contactId, taskId, notes, tags). Create a mapping schema in your integration tool to ensure data lands in the correct fields. Test mappings with sample records to validate data integrity and handle any type conversions.
