Access to the Contacts API is secured via OAuth 2.0 or API keys. Use your GHL developer credentials to obtain an access token and include it in API requests.
Create an app in Nextdoor to obtain client credentials. Use those credentials to request an access token for GHL API calls and rotate tokens regularly.
Endpoints include: 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 viewed or updated in Nextdoor, pull profile data from GHL to enrich CRM
Actions: use GET /contacts/:contactId to fetch profile data, GET /contacts/:contactId/notes for context, GET /contacts/:contactId/tasks for activity
Method paths: GET /contacts/:contactId, GET /contacts/:contactId/notes, GET /contacts/:contactId/tasks
Key fields: contactId, name, email, phone
Trigger: task or note updates in Nextdoor trigger sync to your internal tools via GHL
Actions: GET /contacts/:contactId/tasks, GET /contacts/:contactId/notes
Method paths: GET /contacts/:contactId/tasks, GET /contacts/:contactId/notes
Key fields: taskId, noteId, contactId
Trigger: new lead capture in Nextdoor creates a contact in GHL
Actions: POST /contacts/ to create, POST /contacts/:contactId/tags to categorize
Method paths: POST /contacts/, POST /contacts/:contactId/tags
Key fields: contactId, tags, businessId
Faster onboarding and quick value with no code automations that connect Nextdoor events to CRM data
Centralized data flow where contact activity from Nextdoor appears in GHL and downstream apps
Fewer maintenance tasks thanks to a robust set of endpoints and triggers that work out of the box
Understand the data elements and processes involved: contacts, tasks, notes, appointments, and tags within the GHL Contacts API and how Nextdoor interactions populate them
A RESTful interface provided by GHL that lets you retrieve and manage contact data, including profiles, tasks, notes, and tags, for use in Nextdoor integrations
The standard authorization framework used to obtain access tokens securely for API calls to GHL
Specific URL paths (endpoints) you call to perform actions like GET /contacts/:contactId or POST /contacts/
Labels you assign to contacts to organize and segment in Nextdoor and downstream apps
When a new lead appears in Nextdoor, create a contact in GHL via POST /contacts/ and start follow up tasks to accelerate conversion
Push task updates from GHL to Nextdoor to keep agents aligned on next steps and ownership
Aggregate contacts, notes and tasks into a single timeline view accessible within Nextdoor context
Register your Nextdoor app in GHL, generate client credentials, and define scopes including contacts.readonly to limit access
Obtain an access token using the OAuth 2.0 flow and securely store it for subsequent API calls
Run test requests to endpoints such as GET /contacts/:contactId to verify data flow into Nextdoor as expected
The Contacts API provides a RESTful interface to access profiles, tasks, notes and tags for contacts in Nextdoor. You can fetch a single contact, retrieve related tasks and notes, and pull business data as needed. This enables enriching CRM records with up to date Nextdoor activity. It also supports creating and updating contacts when new leads arrive. The API is designed for easy integration with no code tools and automation platforms.
Requests are authenticated using OAuth 2.0 tokens or API keys issued by GHL. You will exchange your app credentials for an access token, attach it to your requests, and refresh tokens before they expire. For production, store tokens securely and rotate them on a regular cadence to minimize risk.
Key endpoints include GET /contacts/:contactId to pull profiles, GET /contacts/:contactId/tasks and GET /contacts/:contactId/notes to gather activity, and POST /contacts/ to create new entries. Additional endpoints for notes, appointments and tags let you build a complete picture of contact activity from Nextdoor.
Yes. You can create contacts with POST /contacts/ and assign tasks or notes via related endpoints. Updates to a contact’s information are performed with PUT /contacts/:contactId, and you can attach tasks or tags as part of the workflow.
Rate limits depend on your GHL plan and API access. For typical production workloads, start with a conservative limit and implement exponential backoff for retries. If you anticipate higher volumes, contact support to discuss higher quotas.
Store credentials in a secure vault and rotate tokens on a schedule. Use short lived tokens where possible and implement client secret management practices. Regularly review access scopes to ensure they match the minimum required permissions.
No code automations can trigger on Nextdoor events to create or update contacts, sync tasks and notes, and tag records. Use automation tools to map Nextdoor interactions to GHL actions, creating a seamless lead to CRM workflow without writing code.
Due to high volume, we will be upgrading our server soon!
