Creating Subscription Keys on Azure

For unlimited traffic to your HTTP endpoint, you must create an Azure subscription for the LUIS service. The Azure subscription creates metered access keys to your endpoint following a payment plan. See Cognitive Services Pricing for pricing information.

The metered plan allows requests to your LUIS account at a specific rate. If the rate of requests is higher than the allowed rate of your metered account per minute or per month, requests receive an http error of "429: Too Many Requests."

To create your key, follow these steps:

  1. Sign in to the Microsoft Azure portal
  2. Click the green + sign in the upper left-hand panel and search for “LUIS” in the marketplace, then click on Language Understanding Intelligent Service (preview) and follow the create experience to create a LUIS subscription account.

    Azure Search

  3. Configure the subscription with settings including account name, pricing tiers, etc.

    Azure API Choice

  4. Once you have created the LUIS subscription account, you can view the access keys generated in the Resource Management->Keys blade. Test your access keys in your luis.ai account, or by following the LUIS documentation to create a new endpoint application.

Using LUIS access keys in luis.ai

In order to use the access keys you created in Azure, you need to log in to luis.ai and add the new access keys as part of publishing your app.
