Everything the UI can do, the API can do.
Full REST API. Built for AI agents. Zero locked features.
API highlights.
Not an afterthought. The API is how we built the product.
Full CRUD on all resources
Contacts, campaigns, posts, funnels, referrals, affiliates. Every object is an API resource.
Scoped API keys
Per-pillar scopes — contacts, campaigns, blog, funnels, and more. Issue keys per integration, revoke individually. SHA-256 hashed at rest.
Webhook subscriptions
Subscribe to any event: contact.created, campaign.sent, referral.converted. Real-time delivery.
Event-driven architecture
Every action emits an event. Build reactive workflows, audit trails, and real-time dashboards.
AI agents operate GrowthFox natively.
Claude, GPT, Cursor — point any agent at the API. Spin up campaigns, build funnels, manage contacts without touching the dashboard. (MCP server on the roadmap.)
# AI agent via the API
agent: "Create a welcome sequence for new subscribers with 3 emails, starting immediately after signup."
GrowthFox API: Sequence created. 3 emails drafted. Trigger set to contact.created.
Simple, predictable API.
RESTful. JSON. Bearer token auth. No surprises.
