Azure OpenAI DALL-E - Generate Images using Postman

Here is a simple guide on how to generate images using Azure OpenAI DALL-E via Postman.

Before starting off, I am assuming you will already have a Azure OpenAI subscription that is ready to be used.

Azure OpenAI Studio

1. Go to Azure OpenAI Studio : https://oai.azure.com/

2. Click on DALL-E under the Playground section

   

3. Click on ‘View Code’

4. Select ‘json’ from the dropdown, and copy the OAI API Key (hidden text).

Postman

1. Create a new POST Request with the following values:

   • Query Params api-version : 2023-06-01-preview

   • Request Headers

     api-key : {Paste the OAI API Key copied previously)

   • Body

     Paste this JSON as the Request Body and edit as needed:

     1
     2
     3
     4
     5
     {
       "prompt": {Add Your Image Prompt here},
       "n": 1,
       "size": "1024x1024"
     }
     

2. On response, you might get a "status": "notRunning" as response. This is normal.

3. Open the Response Headers tab and copy the URL from operation-location header

   

4. Make another request, this time a GET (instead of a POST) request with the URL copied from Step 3.
5. Response returned should return the generated image URL
