What is the body structure for requesting a signature comparison? For example: “{"signature1": "<base64_encoded_signature1>", "signature2": "<base64_encoded_signature2>"}”
I want to test the MLSkills from Postman.
Thank you very much
Hi @lvelizg
I think this will help
There is also signature similarity activity in GenAi Activities that can also be helpful
Activities - Signature Similarity
For that this can help
Hope this helps 
Thank you for your response. However, I need clarification on how to call the MLSkills Signature Comparison service via API from other applications, outside of UiPath.
I have made the service public, so I already have the endpoint and the key. However, I’m unsure about the structure of the body message—specifically, the JSON tags and other required parameters.
To better understand this, I’m trying to test the service through Postman. My assumption for the body structure is something like this:
“{"data": [{"image1": "", "image2": ""}]}”
Could you please provide the specifications for the input parameters that the service requires? This would help me ensure the request is correctly formatted.
