Begin by obtaining your GHL API credentials for the Custom Fields API and selecting an authentication method (API key or OAuth). Ensure the allowed scope matches locations/customValues.readonly so your integration can read values.
Generate or use an ActiveCollab API token and configure it in your integration settings to securely access locations and fields.
GET /locations/:locationId/customValues; GET /locations/:locationId/customValues/:id; locations/customValues.write; POST /locations/:locationId/customValues; PUT /locations/:locationId/customValues/:id; DELETE /locations/:locationId/customValues/:id; locations/customFields.readonly; GET /locations/:locationId/customFields; GET /locations/:locationId/customFields/:id; GET /custom-fields/:id; GET /custom-field/object-key/:key; locations/customFields.write; POST /locations/:locationId/customFields; PUT /locations/:locationId/customFields/:id; DELETE /locations/:locationId/customFields/:id; locations/tags.readonly; GET /locations/:locationId/tags
Trigger: when a location is updated in ActiveCollab or on a scheduled cron.
Actions: pull values via GET /locations/:locationId/customValues and push to ActiveCollab; map locationId and value fields.
GET /locations/:locationId/customValues
Fields: locationId, id, value
Trigger: when a new value is added in ActiveCollab.
Actions: POST /locations/:locationId/customValues to create or PUT /locations/:locationId/customValues/:id to update; map fields accordingly.
POST /locations/:locationId/customValues
Fields: locationId, id, value
Trigger: when field definitions change in GHL.
Actions: GET /locations/:locationId/customFields and GET /custom-fields/:id to retrieve definitions; optionally POST/PUT to update definitions as needed.
GET /locations/:locationId/customFields
Fields: locationId, id, name
No-code benefit: rapid setup without custom programming; use built-in endpoints to map fields and values between GHL and ActiveCollab.
No-code benefit: automatic data sync and real-time updates based on events and schedules.
No-code benefit: scalable workflows with minimal maintenance.
Key elements include endpoints, fields, values, authentication, and data mapping; processes cover setup, testing, and monitoring.
A defined set of rules that enables software components to communicate and exchange data.
The method used to verify identity and grant access to an API.
A specific URL that represents a resource or action in an API.
Permissions granted to an API credential detailing which resources can be accessed.
Create a mapping layer that normalizes values automatically as they flow from GHL to ActiveCollab to ensure consistency.
Implement retry strategies and friendly error messages to keep data moving even when an endpoint has a hiccup.
Provide a guided setup wizard that steps users through authentication, endpoint selection, and field mapping.
Define which fields to sync, collect credentials, and configure the required scopes and tokens.
Set up endpoints in GHL, map to ActiveCollab fields, and test data flows.
Run test syncs, review logs, adjust mappings, and enable live operation with alerts.
The GHL Custom Fields API lets you read and write metadata about your records in GHL. It is designed to work with apps like ActiveCollab to enrich your data with structured custom values and fields. By leveraging the endpoints listed, you can fetch, create, update, and delete custom values and fields as needed.
To authenticate, obtain your GHL API credentials and choose a secure method (API key or OAuth). Configure the app or middleware to pass the credentials with each request and scope the access to locations/customValues.readonly to limit exposure. In ActiveCollab, generate an API token and store it securely, using it to authorize requests from your integration layer.
Use endpoints like GET /locations/:locationId/customValues, GET /locations/:locationId/customFields, and GET /custom-fields/:id for read operations. For updates, use POST, PUT, or DELETE endpoints as needed. Map locationId to the correct location in ActiveCollab and synchronize the corresponding value and field IDs.
Yes. With proper endpoint mapping and field-level configuration, you can set up automated syncing and avoid custom code. The platform supports creating and updating values and fields via standard REST calls, then aligning them with ActiveCollab fields in your workflow automation tool.
Common issues include authentication failures, insufficient scopes, or rate limits. Validate credentials, confirm scopes for reading custom values and fields, and implement exponential backoff and retries. Monitor API responses to identify blocked requests and adjust mappings accordingly.
Best practices include consistent field naming, clear one-to-one mappings, and regular audits of data integrity. Use normalization, set sensible defaults, and log changes to troubleshoot issues quickly.
Monitoring can be done through your integration tool’s logs and via GHL’s activity data. Set up alerts for failures, track endpoint usage, and review change history to diagnose issues and verify data alignment.
Due to high volume, we will be upgrading our server soon!
