Requests to the Contacts API require authentication via an API key or OAuth token. Include the token in the Authorization header of every call.
Connect MyASP to your GHL account using the App Connector, then test with a sample contact to verify permissions and scope.
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 updated in MyASP, fetch the latest data from GET /contacts/:contactId.
Action: upsert contact data in your CRM using data from GET /contacts/:contactId.
GET /contacts/:contactId
contactId, email, name
Trigger: new or updated contact prompts a task to be created.
Action: POST /contacts/:contactId/tasks to create follow-up tasks.
POST /contacts/:contactId/tasks
contactId, taskTitle, dueDate
Trigger: when a note is added to a contact in MyASP, sync it via the API.
Action: GET /contacts/:contactId/notes and POST /contacts/:contactId/tags to tag contacts.
GET /contacts/:contactId/notes
contactId, noteId, content
Automate CRM workflows without writing code.
Keep data in sync across systems using simple REST calls.
Launch faster with ready-to-use endpoints and field mappings.
Below are essential terms and the processes used to integrate Contacts API with MyASP.
An API is a set of rules that lets software communicate and exchange data over the internet.
The method to verify identity and grant access, usually via API keys or OAuth tokens.
A specific URL path that performs a defined operation, such as retrieving a contact.
A server-to-server push mechanism that sends data in real time.
Fetch contact details and trigger nurture emails or tasks when a new lead is added.
Create onboarding tasks from contact events to guide new users through setup.
Use notes content to automatically tag and segment contacts for targeted campaigns.
Grant permissions and obtain API credentials from GHL and MyASP.
Select endpoints and map fields between systems to ensure data flows correctly.
Run tests, verify data integrity, then enable the automation for production.
The Contacts API lets you read and manage contact data within GHL, including details, notes, tasks, and more. You can perform create, update, and delete operations as needed. Make sure you include a valid API key or OAuth token in your requests. In practice, start with GET /contacts/:contactId to verify access before attempting writes.
To authenticate, create an app in GHL and obtain credentials. Use either an API key or OAuth flow to authorize requests. In MyASP, configure the connected app to use those credentials and test with a sample contact to confirm permissions.
Available endpoints include retrieving contact data, tasks, notes, and basic CRM actions like creating or updating records. The list above shows representative paths; you may not need all endpoints for every page, but you can combine them as needed for your workflow.
Yes. Use POST to create new contacts or POST /contacts/:contactId/tasks to create tasks, and PUT to update existing records. Deleting is supported via DELETE for certain endpoints. Ensure you have the correct permissions before performing write operations.
There are generally rate limits per API key or OAuth token. Plan-specific quotas apply, and you should design integrations to batch requests when possible. If you hit limits, implement backoff and retry logic.
Field mapping is done by aligning source fields to target fields and ensuring data formats are compatible. Use IDs where possible, and test with sample records to verify that values flow correctly between GHL and MyASP.
Test the integration in a sandbox or staging environment by running end-to-end flows: authenticate, call endpoints, and verify responses. Use sample data to simulate real scenarios before going live.
Due to high volume, we will be upgrading our server soon!
