Frequently Asked Questions

What authentication methods are supported?

Supported methods include API keys and OAuth 2.0 where applicable. Use server side authentication and never expose keys in client side code. For Zapier style apps, tokens are rotated regularly.

Read only endpoints fetch data such as GET /contacts/:contactId and GET /contacts/. Write endpoints include POST, PUT, and DELETE variants like POST /contacts/ and PUT /contacts/:contactId.

Map fields by aligning contact identifiers, emails, names, and phone numbers. Use tag data to enrich records. Use a sample mapping table to validate data flow between systems.

Yes, you can trigger creation of tasks via POST /contacts/:contactId/tasks. You can also update task status with completed endpoint. Ensure permissions are configured for the target account.

The API enforces rate limits per your GHL plan. If you hit limits, implement backoff and scheduled sync. Consider batch requests where supported.

Common errors include invalid IDs, missing fields, and expired tokens. Use error codes to retry with backoff. Log and alert on failures.

While no code options exist, you can use the Zapier app connector to create no code automation between GHL and Earth Class Mail. For deeper customization, use the API directly.
