How to connect Custom Fields API with ActiveTrail

This guide explains how to connect GHL’s Custom Fields API with ActiveTrail using the Zapier App Connector, covering authentication, endpoints, and common use cases.

Authentication for Custom Fields API

Authenticate your GHL account by using a valid access token with the appropriate scopes for customValues and customFields, and keep tokens secure.

Authentication for ActiveTrail

Connect ActiveTrail by providing your API key or OAuth credentials in the Zapier app settings, then test the connection.

GHL API Endpoints Used

1) GET /locations/:locationId/customValues — Read all custom values for a location 2) GET /locations/:locationId/customValues/:id — Read a single custom value 3) locations/customValues.write — Update capability for custom values 4) POST /locations/:locationId/customValues — Create a new custom value 5) PUT /locations/:locationId/customValues/:id — Update a custom value 6) DELETE /locations/:locationId/customValues/:id — Delete a custom value 7) locations/customFields.readonly — Readonly access for custom fields 8) GET /locations/:locationId/customFields — Read custom fields for a location 9) GET /locations/:locationId/customFields/:id — Read a single custom field 10) GET /custom-fields/:id — Read a custom field by id 11) GET /custom-field/object-key/:key — Read a field by key 12) locations/customFields.write — Update capability for custom fields 13) POST /locations/:locationId/customFields — Create a custom field 14) PUT /locations/:locationId/customFields/:id — Update a custom field 15) DELETE /locations/:locationId/customFields/:id — Delete a custom field 16) locations/tags.readonly — Readonly tags for locations 17) GET /locations/:locationId/tags — Read tags for a location

Best 3 connections for Custom Fields API and ActiveTrail

Connection 1: Read and sync custom values

Trigger: When a custom value is created or updated in GHL, push the change to ActiveTrail.

Actions: Use GET /locations/:locationId/customValues to fetch values and POST /locations/:locationId/customValues to create or PUT /locations/:locationId/customValues/:id to update; map values to ActiveTrail fields.

Methods: GET for reads, POST for creates, PUT for updates, DELETE when needed.

Key fields: locationId, id for a specific value, and the value payload aligned to ActiveTrail fields.

Connection 2: Custom Fields definitions

Trigger: When a field definition is modified, update ActiveTrail field schema.

Actions: GET /locations/:locationId/customFields and POST /locations/:locationId/customFields to define new fields.

Methods: GET, POST, PUT, DELETE for fields.

Fields: locationId, id, fieldKey, fieldLabel.

Connection 3: Look up field by key

Trigger: Retrieve a field by its key or id to map to ActiveTrail.

Actions: GET /custom-field/object-key/:key and GET /custom-fields/:id.

Methods: GET only for lookup by key or id.

Fields: id or key; mapping to ActiveTrail fields.

Benefits of a no-code integration

Zero-code setup with ready-made endpoints accelerates deployment.

Rapid integration without custom development and maintenance.

Secure, scalable data sync between GHL and ActiveTrail with audit trails.

Frequently asked questions

What authentication is required for the GHL Custom Fields API?

You authenticate with GHL using OAuth 2.0 tokens that include the necessary scopes for customValues and customFields. Store tokens securely and rotate them as recommended by your security policy. Ensure the token has read/write access to the endpoints you plan to use. In Zapier, connect the GHL app to authorize access and test the connection before proceeding. If you’re using service accounts or API keys, keep them out of version control and use encrypted storage.

The typical endpoints you’ll use are those that read and write custom values and fields, such as GET /locations/:locationId/customValues and POST /locations/:locationId/customValues for values, as well as GET /locations/:locationId/customFields and POST /locations/:locationId/customFields for field definitions. For lookups, you may use GET /custom-fields/:id or GET /custom-field/object-key/:key to retrieve by key. Map the responses to ActiveTrail fields in your Zapier templates.

Yes. Use GET /custom-field/object-key/:key or GET /custom-fields/:id to retrieve a specific field by its key or id. This enables precise field mapping in ActiveTrail. Ensure your call includes the proper location context if required by your setup. Handle missing keys gracefully and implement fallback logic in your automation.

No extensive coding is required. The integration uses the GHL endpoints in a no-code connector like Zapier, enabling you to map fields and triggers without writing code. You can create multi-step zaps that respond to changes in GHL data and push updates to ActiveTrail. If you need advanced transformations, you can add minimal formulas or built-in steps within Zapier.

GHL API rate limits apply. Plan for bursts during sync tasks and implement exponential backoff and retries in your automation. Monitor quota usage in your GHL developer console and consider batching requests where possible to stay within limits. If rate limits are reached, pause non-critical tasks and retry after the recommended interval.

Start by checking the connected accounts in Zapier for proper authentication. Review endpoint responses for error codes and messages, and enable detailed logging. Validate payload schemas between GHL and ActiveTrail mappings. If issues persist, consult the endpoint docs and verify permission scopes.

Map GHL field values to the corresponding ActiveTrail contact properties, ensuring data types match (text, numbers, dates). Use lookup fields for deterministic mappings and set up test records to verify the flow. Maintain a clear data dictionary to keep mappings consistent as your fields evolve.
