Manage Consumer Credentials

A consumer is an application or a developer who consumes the API. The authentication plugin enabled on a route locks down access, requiring consumers to obtain credentials to access the API.

Consumers are typically created after APIs are published while developers come to apply for credentials. A consumer requires a unique username to be created. As part of the authentication configuration, you would also add one of the authentication plugins from the list above to the consumer's plugin field.

In this tutorial, you will create a consumer with key authentication, and then use the key to access the API with key authentication.

Prerequisites

  1. Obtain a user account with Super Admin or API Provider role.
  2. Publish a service.
  3. Set up API authentication.

Add a Consumer

  1. Select Services from the side navigation bar and then click the target service.

  2. Select Consumers from the side navigation bar and then click Add Consumer.

  3. From the Add Consumer dialog box, do the following:

    • In the Gateway Group field, choose Test Group.
    • in the Name field, enter Alice.
  4. Click Add.

Enable Key Authentication for the Consumer

  1. Select Consumers from the side navigation bar and then select Alice.

  2. In the Plugins field, search the key-auth plugin.

  3. Click the Plus icon (+) and a dialog box appears.

  4. Apply the following configurations:

    {
    "key": "secret-key"
    }
  5. Click Enable.
