Use your GHL API key and the objects schema scope (objects/schema.readonly) to authorize requests to the Custom Objects API and protect data access.
In Act-On, create a connection using API credentials and grant the necessary read/write access to GHL data for the integration.
GET /objects/:key, GET /objects, objects/schema.write, objects/record.readonly, GET /objects/:schemaKey/records/:id, objects/record.write, POST /objects/:schemaKey/records, PUT /objects/:schemaKey/records/:id, DELETE /objects/:schemaKey/records/:id
Trigger: you need up-to-date object schemas and lightweight reads to drive segments in Act-On.
Actions: use GET /objects and GET /objects/:key to fetch schemas and preview object structure for mapping.
Method Path: GET /objects and GET /objects/:key for schema discovery.
Key fields: key, schemaKey, and object attributes used for mapping.
Trigger: new or updated records in Act-On should be reflected in GHL.
Actions: POST /objects/:schemaKey/records to create, PUT /objects/:schemaKey/records/:id to update.
Method Path: POST and PUT endpoints for records.
Key fields: id, schemaKey, and object-specific fields.
Trigger: maintain data consistency with minimal downtime.
Actions: PATCH/PUT to modify existing records and maintain history.
Method Path: PUT /objects/:schemaKey/records/:id for updates.
Key fields: id, lastModified, and schemaKey.
Faster onboarding with ready-made templates and drag-and-drop mappings.
Real-time data sync reduces manual data entry and errors.
Consistent reporting and richer audience insights across tools.
This glossary covers the core concepts used when connecting GHL’s Custom Objects API with Act-On, including endpoints, schemas, records, and data mappings.
A URL path that allows programmatic access to resources in the GHL API.
The process of verifying identity to access GHL resources and perform actions.
The structure that defines a custom object in GHL, including fields and relationships.
A single instance of a custom object stored in GHL.
Set up a trigger in Act-On to push updated contact data into a GHL custom object via the API, ensuring records stay fresh.
Map fields between Act-On and GHL schemas to tailor campaigns based on object attributes.
Leverage versioned object records and change logs to monitor data quality across systems.
Collect and securely store GHL API key and Act-On credentials for the integration.
Enable the required endpoints (GET, POST, PUT, DELETE) for your object schema and map fields to Act-On.
Run tests to validate data flow, monitor for errors, and enable production syncing.
The GHL Custom Objects API exposes endpoints to read, write, and manage custom objects. It provides programmatic access to object schemas, records, and metadata. By reading the docs, you can understand the available operations and how to structure your requests. Use the API responsibly, respecting rate limits and security best practices.
Authentication uses your GHL API key and appropriate scopes (such as objects/schema.readonly). You’ll also configure the Act-On side to accept tokens or credentials from GHL. Always rotate credentials and store them securely to protect your data.
Read operations cover endpoints like GET /objects and GET /objects/:key. Write operations use POST, PUT, and DELETE endpoints to create, update, or remove records. Not all endpoints may be enabled in a given plan; enable only what you need.
Yes. You can map fields between GHL custom objects and Act-On contact or campaign attributes. This ensures data flows to the right fields for segmentation and automation. Use field mappings to maintain consistency across systems.
Test the connection by performing a dry run of a create or update operation. Check response codes and verify data in Act-On and GHL. Monitor logs and set up alerts for failed requests.
Rate limits depend on your GHL plan and API usage. If you hit limits, throttle requests, batch updates, or stagger syncs. Contact support if you anticipate high volumes.
No-code options exist via integration builders or automation platforms that support webhooks and data mapping. You can set up triggers and actions without writing code. For more complex needs, you may extend with custom scripts.
Due to high volume, we will be upgrading our server soon!
