Flowise

Flowise builds LLM flows from nodes, and its OpenAI-compatible chat model nodes accept a custom base URL.

See Connect your harness for your base URL, key, and model IDs.

1. Add a ChatOpenAI Custom (or ChatOpenAI) node to your flow.
2. Create a credential with your TapPass agent API key.
3. In the node, set Base Path / Base URL to https://app.tappass.ai/v1.
4. Set the model name to a prefixed ID, for example anthropic/claude-sonnet-4-5-20250929.

For nodes without a base-URL field, use a generic HTTP / custom tool node pointed at https://app.tappass.ai/v1/chat/completions with a Bearer header.

Run the flow once, then confirm a governed event for your agent in the TapPass console.
