I am trying to use OCR.Space within a Microsoft Flows.
I am testing the recognition of the jpg file provided in the code examples provided (Free OCR API).
I can successfully use the API using Postman with my personal apikey and the “base64image” parameter corresponding to that image.
When I try to call the API with a Microsoft Flows HTTP Post request with the exact same parameters, I fail with this error message :
Bad Request - Request Too Long
HTTP Error 400. The size of the request headers is too long.
Any idea on what is going wrong or how I could go further ?
Have you been able to get a workaround for this please? I have tried all the above and get similar errors. Can you advice the reason of error, or perhaps if we can use plain JSON as content type to fire the POST requests, may be it would be simpler to work with.
