To access the Contacts API you connect with a GHL API token that carries the contacts.readonly scope. Include the token in the Authorization header for each request to securely read contact data.
In the Zapier app connector connect Oktopost to the GHL Contacts API by providing the API token and selecting the Contacts API scope. Use the supported authentication method in the app and test a simple read to confirm connectivity.
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; GET /contacts/; 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 Oktopost, then fetch the latest data from the Contacts API to keep records in sync
Actions read contact data from the API and update or create corresponding records in Oktopost, including related notes and tasks
GET /contacts/:contactId
id, email, name, status
Trigger when a new contact is created in Oktopost, then create the corresponding contact in the GHL Contacts API
Actions create a new contact in Contacts API and optionally attach initial notes or tasks
POST /contacts/
email, name, businessId
Trigger when a tag is added in Oktopost, then update tags on the Contacts API record
POST /contacts/:contactId/tags
contactId, tag
Zero code setup with drag and drop workflow builders in Zapier to automate data flow
Fast deployment with prebuilt actions for read create update and tag operations across both apps
Scales with your team as data moves between Oktopost and the Contacts API
Key elements include endpoints for resources, triggers that start automations, actions that perform operations, methods that define HTTP verbs, and key fields used to map data.
A specific path on the API that performs a named operation on a resource
The process of proving identity to access the API, typically via tokens or OAuth
The data sent with a request or returned in a response representing the resource state
HTTP verbs like GET POST PUT DELETE that describe the action taken
Enrich contact records in GHL with data pulled from Oktopost events to create richer profiles
Keep engagement history synchronized between Oktopost and the Contacts API for a complete activity timeline
Automatically create tasks and notes in Oktopost based on Contacts API activity to drive follow ups
Establish a secure connection by supplying your GHL API token in the Oktopost Zapier app connector
Select endpoints such as GET /contacts/:contactId and POST /contacts, then map data fields between apps
Run tests, review logs, and deploy the workflow to production
The Contacts API scope in this setup is read only, defined as supports the contacts.readonly. This ensures you can fetch contact data and related resources without risking unintended data changes. If you need write access, you would adjust scope accordingly and review governance. In practice you can still perform updates from Oktopost via allowed endpoints when your token grants write permissions.
No code is required thanks to Zapier app connectors. You can bridge Oktopost and GHL using prebuilt actions and triggers. For more complex needs you can add custom steps, but most use cases can be solved without writing code.
Authentication is handled by your GHL API token or the OAuth flow supported by the Zapier connector. You will add credentials in the app connection screen and test a sample request to confirm access.
Common endpoints include GET /contacts/:contactId for retrieving data and POST /contacts for creating records. Depending on the workflow you may also use notes, tasks and tags endpoints to enrich the data model.
Currently this integration emphasizes read operations for safety. If write is required, you must update the scope accordingly and perform thorough testing before going live.
Security is enforced via token based authentication, encrypted connections, and scoped access. Rate limits depend on your GHL plan and the Zapier app, so plan for retries and backoff in your workflows.
You can view logs in Zapier and in the GHL integration section. If you encounter issues check endpoint responses, authentication status, and how fields are mapped in your workflow.
Due to high volume, we will be upgrading our server soon!
