Prerequisites

Before you begin, ensure you have the following:

1. Microsoft Azure Account: To access the Microsoft Bot Framework.
2. Bot Registration: A registered bot with Direct Line channel enabled in Azure.
3. Postman Installed: Download and install Postman from the official website.
4. Basic Knowledge of APIs: Understanding of RESTful APIs and how to make HTTP requests.

With these prerequisites, you’ll be ready to follow along and successfully interact with the Microsoft Bot Framework using Postman.

Get the Directline Secret

Open the Azure Bot Service, navigate to Channels, and click on Direct Line.

Click on the Default Site.

View the secret and copy it for the upcoming steps. Save it in a secure location, as we will need this secret to generate a DirectLine token.

Create a new Postman Collection for Directline APIs

First, create a new collection in Postman. Click on “New” and then select “Collection.” Name the collection “Directline APIs.”

Navigate to the Authorization tab and select “Bearer Token” as the authentication type. Enter the Directline Secret in the Token field.

Generate Directline Token

Add a new POST request to your Postman collection. Set the Authorization type to “Inherit auth from Parent.” Enter the request URI as https://directline.botframework.com/v3/directline/tokens/generate.

Go to the Body tab, select “raw,” and choose “JSON” as the format. Enter the following request body. While this step is optional, it is recommended for optimal results.

{
  "user": {
    "id": "string",
    "name": "string"
  },
  "trustedOrigins": [
    "string"
  ]
}

Finally, send the request to obtain the Directline Token using Postman.
