Image Prompt Flow Endpoint Consumption

Question

Hi, I have deployed the image prompt flow from Azure AI Foundry utilizing Azure OpenAI GPT4vision. Currently, I want to consume this endpoint from my own application, can someone assist on how to consume this endpoint in my own application or Postman first? Thank you, because I receive the 424 error when I try to consume the endpoint in Postman. Need advice on this matter. Thank you.

Farah Diana Masri Greetings!

Did you check Process images in prompt flow already?

You can deploy a flow to an online endpoint for real-time inference.

Currently the Test tab in the deployment detail page doesn't support image inputs or outputs.

For now, you can test the endpoint by sending request including image inputs.

To consume the online endpoint with image input, you should represent the image by using the format {"data:<mime type>;<representation>": "<value>"}. In this case, <representation> can either be url or base64.

If the flow generates image output, it is returned with base64 format, for example, {"data:<mime type>;base64": "<base64 string>"}.

Also, see Troubleshoot guidance for prompt flow if it helps.

Do let me know if that helps or have any further queries.
