Use secure API credentials with the required scopes. For read operations ensure the scope is businesses.readonly; for write operations use businesses.write. Always use HTTPS, store keys securely, and rotate credentials on a regular schedule.
Authenticate ActiveCampaign requests using a secure API key or OAuth token. Assign the appropriate scopes and keep credentials confidential. Use server-to-server authentication where possible and enable token rotation and audit logging.
Key endpoints include GET /businesses to list businesses, GET /businesses/:businessId to retrieve a single business, POST /businesses to create a business, PUT /businesses/:businessId to update a business, and DELETE /businesses/:businessId to remove. These endpoints are governed by the appropriate scopes (read or write) and are used to manage business data within the integration.
Trigger: when a new business is created in the Business API
Actions: create or update a contact in ActiveCampaign, tag the record, enroll in an onboarding automation
GET /businesses
id, name, status, owner, createdAt
Trigger: business updated with high priority data
Actions: map fields to ActiveCampaign contact fields, update segments
GET /businesses/:businessId
businessId, name, revenue, status
Trigger: a contact subscribes to a campaign
Actions: create or update a business in the Business API based on contact activity
POST /businesses
businessId, contactId, status

A quick glossary of terms used in this guide, including API, endpoint, webhook, scopes, and field mapping.
Application Programming Interface; a set of rules that allow one app to talk to another.
A specific route in an API that returns data or performs an action.
An open standard for token-based authentication that grants limited access.
A real-time notification pushed from one system to another when an event occurs.
Trigger a welcome sequence when a new business is created in the API; enroll the contact in a lifecycle automation.
Enrich leads with business data and feed scores into ActiveCampaign’s scoring model.
Use endpoint triggers to re-engage inactive businesses with targeted email sequences.
Register your application in the GHL developer portal and generate API keys for the Business API.
Create a data map between Business API fields and ActiveCampaign contact fields.
Test all integrations in a sandbox and then deploy to production with monitoring.
Both API keys and OAuth tokens are supported for authenticating calls to the Business API and ActiveCampaign. Use the method that fits your architecture and enforce HTTPS. In production, rotate credentials regularly and monitor for unusual access patterns.
The endpoints cover basic CRUD for businesses including listing, retrieving, creating, updating, and deleting records. You will typically use GET /businesses, GET /businesses/:businessId, POST /businesses, PUT /businesses/:businessId, and DELETE /businesses/:businessId. Endpoint availability is governed by the assigned scopes.
You can set up many integrations without code using built in automations and webhooks. Some light scripting can help with field mapping and data transformation if your workflow requires it. For a fully no code experience, rely on templates and connectors that handle authentication and error handling.
Security is built on HTTPS, proper authentication scopes, and credential management. Rotate keys regularly, use IP allowlisting where possible, and keep audit logs of access and changes.
Yes. You can map custom fields from the Business API to ActiveCampaign contact fields to keep data aligned. Plan mappings during setup and validate data types and formats.
Test in a sandbox with sample data and controlled triggers to verify end to end flows. Check for data consistency, error handling, and performance before going live.
API keys are issued in the GHL developer portal. Endpoint documentation is available in both GHL and ActiveCampaign developer docs and in the combined integration guide. Use these references for exact paths and payload structures.
Due to high volume, we will be upgrading our server soon!
