Developer Documentation

API & Integration

Botpress exposes a comprehensive REST API for agent development, documented at the API Reference section of the Botpress docs. Developers can programmatically create agents, manage knowledge bases, trigger workflows, and retrieve conversation analytics.

LLM Provider Configuration

The Autonomous Engine supports pluggable LLM providers. You can configure agents to use:

OpenAI (GPT-4 and variants)
Anthropic (Claude models)
Groq (fast inference)
Hugging Face (open-source models)

Switch providers per agent via the studio UI or API payload.

Key Architectural Components

Agent Studio — Visual builder for conversation flows and agent logic
Autonomous Engine — LLM-driven runtime for dynamic conversation handling
Knowledge Bases — RAG-powered document ingestion and retrieval
Tables — Structured data store for conversation context and session state
Channels API — Unified webhook layer for WhatsApp, Slack, Messenger, Instagram, and more

Deployment

Hosted on AWS with automatic horizontal scaling. No self-hosting option is required; infrastructure is fully managed. Integrate via OAuth for Zendesk/Intercom or use webhooks and the REST API for custom stack connections.
