All REST samples revolve around what you can do with a knowledge base, which is made up of FAQs or product manuals where there is a question and an answer. QnA Maker gives you more control over how to answer questions by allowing you to train a chat bot to give answers in a variety of ways that feels more like natural, conversational exchanges.

Getting Started


For each sample, a subscription key is required from your Azure Portal account.

With the exception of creating a new knowledge base, these samples will require your QnA Maker account knowledge base ID. To find your knowledge base ID, go to My knowledge bases and select View Code on the right. You'll see the http request and your knowledge base ID is in the topmost line: for example, POST /knowledgebases/2700e6b9-91a1-41e9-a958-6d1a98735b10/.... Use only the ID.

Run the sample

  1. Create a Node.js project in your favorite IDE or create one in Visual Studio 2017 by expanding Javascript in the new project popup and selecting Node.js, then Blank Node.js Console Application.

  2. Copy/paste the sample you want to test in the app.js file.

  3. Add your Azure subscription key for QnA Maker and add your knowledge base ID (if applicable) to the code at the top.

  4. Run the sample.
