To use the Contacts API you authorize requests via OAuth 2.0, obtain an access token, and refresh tokens as needed.
Create an OAuth client in WhatsAble, obtain client credentials, and configure redirect URLs. Use the access token to authorize each API call.
Primary endpoints include: GET /contacts/:contactId, GET /contacts/:contactId/tasks, GET /contacts/:contactId/notes, POST /contacts/, PUT /contacts/:contactId, DELETE /contacts/:contactId, POST /contacts/:contactId/tasks, PUT /contacts/:contactId/tasks/:taskId, DELETE /contacts/:contactId/tasks/:taskId, GET /contacts/ and GET /contacts/business/:businessId. All calls require Bearer token and respect the contacts.readonly scope.
Trigger when a contact is created or updated in WhatsAble to fetch the latest details from Contacts API.
Actions: retrieve contact details, fetch latest tasks and notes, sync basic fields.
GET /contacts/:contactId
Key fields: id, name, email, phone, status
Trigger when a task is created or updated in WhatsAble to reflect in Contacts API.
Actions: create/update tasks via POST /contacts/:contactId/tasks and PUT /contacts/:contactId/tasks/:taskId.
POST /contacts/:contactId/tasks
Key fields: taskId, title, dueDate, completed
Trigger when notes or tags are updated to keep both systems aligned.
Actions: POST /contacts/:contactId/notes, POST /contacts/:contactId/tags, and fetch notes for display.
POST /contacts/:contactId/notes
Key fields: noteId, content, tagId, createdAt
Fast setup with drag‑and‑drop configuration—no coding required to connect data.
Automated data sync reduces manual entry and data drift across systems.
Scalable workflows across teams with role‑based access and audit trails.
This section defines core elements: API endpoints, authentication, requests, responses, data mapping, and workflow processes.
A set of rules that lets software applications communicate and exchange data.
A specific URL path in an API used to access a resource or perform an action.
An authorization framework that grants access to APIs without sharing user credentials.
The data sent or received in an API request or response.
Automatically pull extra fields (company, social profiles) when a new contact is created.
Route tasks to the right team based on contact lifecycle stages and activity.
Synchronize notes and tags across WhatsAble and the Contacts API for unified context.
Create a GHL API client, obtain client ID/secret, and set redirect URLs for WhatsAble.
Define required scopes (e.g., contacts.readonly) and map fields between systems.
Run tests, verify data flows, monitor for errors, and deploy to production.
The integration uses OAuth 2.0 with Bearer tokens for secure access. You’ll obtain an access token during the OAuth flow and refresh it as needed. Always include the token in the Authorization header for each API call. If a token expires, use the refresh token to obtain a new one.
You can access contacts, tasks, notes, appointments, and basic business data associated with a contact. Read-only scope is supported, with write capabilities available for creating and updating records as configured in your app.
Rate limits vary by plan, but typical limits apply per minute per API key. Implement exponential backoff and proper error handling to gracefully retry failed requests. Contact support if you consistently hit limits.
No heavy coding is required. The setup is designed for no-code/low-code environments, with guided configuration and prebuilt endpoints. Some light data mapping and field matching may be needed.
Use field mapping in your integration settings to align source fields with destination fields. Validate on a sample contact to ensure correct data transfer and format.
Yes. Webhooks can be configured to push updates from the Contacts API to WhatsAble or vice versa, enabling real‑time or near‑real‑time sync.
Endpoint details, usage examples, and parameter descriptions are documented in your API provider portal and in this guide. Always refer to the latest docs for accurate syntax.
Due to high volume, we will be upgrading our server soon!
