Access to the Contacts API requires a secure token or OAuth credential. Use the app credentials to authorize requests within the defined scope: contacts.readonly.
0CodeKit authenticates against the GHL Contacts API using OAuth 2.0 or API keys, depending on your setup, to securely access read-only data within the Contacts API.
GET /contacts/:contactId – Retrieve a single contact; GET /contacts/:contactId/tasks – Retrieve tasks for a contact; GET /contacts/:contactId/tasks/:taskId – Retrieve a specific task; GET /contacts/:contactId/notes – Retrieve notes for a contact; GET /contacts/:contactId/notes/:id – Retrieve a specific note; GET /contacts/:contactId/appointments – Retrieve appointments for a contact; GET /contacts/ – List contacts; GET /contacts/business/:businessId – Retrieve contacts for a specific business; contacts.write – permission hint; POST /contacts/ – Create a new contact; PUT /contacts/:contactId – Update a contact; DELETE /contacts/:contactId – Delete a contact; POST /contacts/:contactId/tasks – Create a task for a contact; PUT /contacts/:contactId/tasks/:taskId – Update a task; PUT /contacts/:contactId/tasks/:taskId/completed – Mark a task as completed; DELETE /contacts/:contactId/tasks/:taskId – Delete a task; POST /contacts/:contactId/tags – Add tags to a contact
Trigger: opening a contact in 0CodeKit fetches the contact data and its associated tasks.
Actions: retrieve /contacts/:contactId and /contacts/:contactId/tasks, then display details in the 0CodeKit workspace.
GET /contacts/:contactId
id, name, email, phone, status, tasks
Trigger: selecting a contact reveals its tasks and notes.
Actions: fetch /contacts/:contactId/tasks and /contacts/:contactId/notes and populate a task-note view.
GET /contacts/:contactId/tasks
contactId, taskId, noteId, title, status, dueDate
Trigger: a contact is updated in 0CodeKit.
Actions: update the contact via PUT /contacts/:contactId and manage tags via POST /contacts/:contactId/tags.
PUT /contacts/:contactId
contactId, name, email, tags
Centralized access to contact data across your apps and automations within 0CodeKit.
Faster workflow creation with context-rich data from Contacts API, reducing manual data entry.
Security through read-only scope by default, with optional write permissions when needed.
A concise list of data elements and common processes used when integrating GHL Contacts API with 0CodeKit.
Application Programming Interface: a set of endpoints and methods that let applications interact with each other.
OAuth 2.0 authorization framework used to grant secure access tokens for API calls.
A specific URL in an API that performs a defined action or returns data.
The permission level granted for an API token, e.g., contacts.readonly or contacts.write.
Set up a trigger on contact creation to automatically generate a starter task in 0CodeKit, ensuring onboarding steps begin immediately.
Link notes to related tasks so team members see context in one place, reducing context-switching.
Automatically add or remove tags on contact updates to simplify segmentation and reporting in 0CodeKit.
Configure OAuth credentials or API keys in the 0CodeKit dashboard to establish a trusted connection to the Contacts API.
Select and map the endpoints you plan to use (e.g., get contact, tasks, notes) within your workflows.
Run tests to verify data flow, monitor for errors, and deploy to your live workflows.
Read-only access means you can fetch and read contact data without modifying it. This is ideal for reporting and auditing within 0CodeKit. If your workflow requires updates, you can request higher permissions and adjust scopes as needed. Always follow the principle of least privilege to protect data.
For common workflows, start with retrieving a contact (GET /contacts/:contactId), then load related tasks (GET /contacts/:contactId/tasks) and notes (GET /contacts/:contactId/notes). This provides context for automation and reduces the need for separate lookups.
Test the connection by running a dry-run in 0CodeKit, verifying that data from GET endpoints returns expected fields. Check authentication tokens, scopes, and error responses in your test logs before going live.
OAuth is a common method for secure connections. Depending on your setup, you may also use API keys. Ensure credentials are stored securely in 0CodeKit and rotated regularly. Some environments allow refresh tokens for continued access without re-authentication.
Yes, you can create and update contacts using endpoints like POST /contacts/ and PUT /contacts/:contactId, but these actions require appropriate write permissions and careful handling to avoid data inconsistencies. Start in a test environment to validate behavior.
Tags can be added or updated via POST /contacts/:contactId/tags. Use a clear tagging strategy to support segmentation and automation in 0CodeKit. Be mindful of tag naming conventions to keep data clean.
Integration logs and errors are visible in the 0CodeKit dashboard under the connected apps section. Enable verbose logging if available and monitor API response codes to quickly diagnose issues.
Due to high volume, we will be upgrading our server soon!
