Obtain your credentials from the GHL developer console and grant the app the required scopes for example contacts.readonly to access contacts data.
VirtualPostMail will use the same OAuth token or API key to access the GHL Contacts API. Ensure your app has required permissions and that tokens are stored securely.
Core contact retrieval: GET /contacts/:contactId; Tasks: GET /contacts/:contactId/tasks and GET /contacts/:contactId/tasks/:taskId; Notes: GET /contacts/:contactId/notes and GET /contacts/:contactId/notes/:id; Appointments: GET /contacts/:contactId/appointments; List all contacts: GET /contacts/; Business lookups: GET /contacts/business/:businessId; Write operations: POST /contacts/; PUT /contacts/:contactId; DELETE /contacts/:contactId; Task creation and updates: POST /contacts/:contactId/tasks; PUT /contacts/:contactId/tasks/:taskId; PUT /contacts/:contactId/tasks/:taskId/completed; DELETE /contacts/:contactId/tasks/:taskId; Tag management: POST /contacts/:contactId/tags
Trigger when a contact is created or updated in VirtualPostMail
Actions upsert the contact in Contacts API and optionally create notes or tasks to reflect activity
GET /contacts/:contactId
Key fields id email firstName lastName phone status
Trigger new task or note created in VirtualPostMail
Actions create task or note via Contacts API and link to the same contact
POST /contacts/:contactId/tasks
taskId contactId title dueDate status
Trigger a tag is added to a contact in VirtualPostMail
Actions add tag via POST /contacts/:contactId/tags
POST /contacts/:contactId/tags
tagId name
Automate workflows between GHL and VirtualPostMail without writing code
Keep customer data synchronized in real time across platforms
Speed up onboarding and support with ready made automations
A quick glossary of terms and the processes used when integrating the GHL Contacts API with VirtualPostMail
An API is a set of endpoints and methods that let apps request and manipulate data from a service
A specific URL and HTTP method used to perform an action on the service
The process of proving identity to access an API typically via API keys or OAuth tokens
An HTTP callback URL that notifies your app when certain events occur
Map new signups in VirtualPostMail to the Contacts API create endpoint to build your contact base automatically
Attach notes and tasks with contacts whenever activity occurs in VirtualPostMail to keep history intact
Use the POST /contacts/:contactId/tags endpoint to apply tags based on events in VirtualPostMail
Create an integration in GHL to obtain client credentials and authorize the app with required scopes store securely
In Zapier define triggers actions and searches using the endpoint paths provided
Run end to end tests verify data mapping and deploy to production
No coding is required thanks to the Zapier App Connector and the pre built endpoint actions. Use field mappings to align data between VirtualPostMail and the GHL Contacts API. If you need advanced logic you can still use webhooks or conditional steps in Zapier.
GHL supports OAuth 2.0 and API key methods depending on your account. For most integrations use OAuth to securely obtain access tokens with the required scopes such as contacts.readonly. Store tokens securely and rotate them as recommended. Always follow best practices for credential security and test in a staging environment before going live.
Start with GET /contacts/:contactId to fetch a contact and GET /contacts/:contactId/tasks to pull tasks. Then try POST /contacts/ to create a new contact and POST /contacts/:contactId/tasks to add tasks.
Yes, you can manage tasks and notes using the corresponding endpoints. Use POST to create, PUT to update, and DELETE to remove items. This keeps activity and history linked to each contact.
Yes, rate limits apply. Use retries with backoff and respect quotas. If you anticipate higher load contact support to discuss options.
Map key fields such as id email name and phone from VirtualPostMail to the Contacts API. Use consistent identifiers to avoid duplicates and enable upsert behavior. Validate data types and handle errors gracefully.
Use Zapier test flows to simulate triggers and actions. Verify data mapping and error handling. Once all tests pass, deploy to production and monitor activity.
Due to high volume, we will be upgrading our server soon!
