OCR via Web API

System

Hi,
I want to send a picture to a API to do the OCR. But after I posted successfully the response told me it doesn't work. The OCR webAPI can't read the body data. The API use the base64 encode for the picture. And when I setup the header to content-type: application/x-www-form-urlencoded,chartset=uft-8, I found in the result the header is still the application/json. How can I configure it?

Thanks,
Xia

@XIA_175253 Can you share why you are using an API action for OCR, instead of using the OCR action? If the API is public, can you also share a link to the API documentation? Thank you!

@XIA_175253 We are currently checking in to address this issue as soon as possible. I will share a new update as soon as this gets addressed. In the meantime, a different body configuration should do something similar. If your body is like foo=url-encoded-bar it should now look like { "foo": "bar"}. Does this body configuration meet your use case as well?

Hi Jozef,
