Question

A developer is building a customer support assistant that must call three internal REST APIs (order lookup, refund status, shipping tracker) based on user intent. The team wants full control over the orchestration loop in their own Lambda code: they will parse the model's tool requests, invoke the APIs themselves, and feed results back to the model in a loop they manage. They do not want AWS to manage the reasoning-and-invocation cycle or maintain agent configuration state. Which Bedrock integration approach best fits these requirements?

Accepted Answer

Use the Converse API with the toolConfig parameter, inspecting stopReason 'tool_use' and appending toolResult content blocks in an application-controlled loop

Answer

Create a Bedrock Agent with three action groups mapped to the REST APIs and let the agent runtime orchestrate tool selection

Answer

Use InvokeModel with a single prompt that concatenates all three API responses ahead of time so no tool calling is needed

Answer

Configure a Bedrock Knowledge Base over the API documentation and rely on retrieval to answer order and refund questions
