  title: Azure API Management AI Gateway Chat and Embed
  summary: Send a chat completion through the AI gateway, then embed the same prompt for retrieval.
  description: >-
    A retrieval-augmented pattern routed entirely through the API Management AI
    gateway. The workflow sends a chat completion request to a deployment to get
    an assistant answer, then sends the original user prompt to an embeddings
    deployment so it can be stored in a vector index for later semantic search.
    Every step spells out its request inline so the flow can be read and
    executed without opening the underlying OpenAPI description.
