Authenticate requests using OAuth 2.0 tokens or API keys issued by GHL. Store credentials securely and rotate them regularly.
Create an OAuth client in MailerCheck and enter the client ID and secret in the integration settings to establish a trusted connection with the GHL Contacts API.
– 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: a contact is created or updated in GHL. Action: fetch contact details and create/update the corresponding contact in MailerCheck using GET /contacts/:contactId and related endpoints.
Actions: GET /contacts/:contactId to retrieve details; POST /contacts/ to create; PUT /contacts/:contactId to update; POST /contacts/:contactId/tasks to sync tasks; POST /contacts/:contactId/notes to sync notes.
GET /contacts/:contactId
contactId, email, firstName, lastName
Trigger: a new or updated task or note in GHL
Actions: map to MailerCheck tasks/notes; use endpoints GET /contacts/:contactId/tasks and GET /contacts/:contactId/notes to fetch data
GET /contacts/:contactId/tasks and GET /contacts/:contactId/notes
taskId, noteId, contactId, title, status
Trigger: appointments booked or updated in GHL
Actions: fetch appointments and business data to create calendar entries in MailerCheck; use GET /contacts/:contactId/appointments and GET /contacts/business/:businessId
GET /contacts/:contactId/appointments
appointmentId, businessId, contactId, date

Obtain OAuth2 tokens or API keys and configure in the MailerCheck integration settings.
Map required endpoints (for example GET /contacts/:contactId) to MailerCheck fields.
Run tests to validate data flow and enable automation in production.
You will typically need read permissions on contacts (scope: contacts.readonly) to pull data and, if you plan to create or update records, write permissions as well. Always secure tokens and rotate keys regularly. If your workflow requires broader access, request additional scopes from your GHL admin. In production, follow least-privilege access practices.
No coding is required if you use MailerCheck’s built-in connectors and a visual mapping interface. However, for complex data transformations or custom field mappings, a developer can extend the integration with small scripts or webhooks. Start with the no-code setup and add code only if needed.
Connections use OAuth 2.0 tokens or API keys, with traffic encrypted in transit and credentials stored securely. Rotate credentials on a defined schedule and monitor access logs. Use least-privilege permissions to minimize risk.
Essential endpoints include GET /contacts/:contactId to fetch a contact, GET /contacts/ to list contacts, and endpoints to fetch related tasks, notes, and appointments. For initial setup, focus on read endpoints; expand to write endpoints as your workflow requires.
Test in a sandbox or staging environment by simulating a contact create/update and verifying data appears correctly in MailerCheck. Use test tokens where available and review error logs. Once verified, promote to production with controlled rollout.
Yes. You can map standard and custom fields between GHL and MailerCheck. Use the field-mapping UI to align names, types, and validation rules, then test the data flow to ensure accuracy across systems.
GHL API rate limits vary by plan. If you anticipate high volume, implement batching, exponential backoff, and caching where appropriate. Check current quotas in your GHL developer docs and contact support for higher limits if needed.
Due to high volume, we will be upgrading our server soon!
