Internal Processing Error - Zoho

Hello! I have had great success in using the API provided in PostMan, however in implementing it from my application I am getting the below response:

{“OCRExitCode”:99,“IsErroredOnProcessing”:true,“ErrorMessage”:[“Some internal processing error occurred. Please give us some time, we are looking into this!”],“ErrorDetails”:"",“ProcessingTimeInMilliseconds”:“0”}

However, when I do it from PostMan it works perfectly with all of the same parameters and headers. Any guidance would be amazing.

Just to clarify: How do you use the OCR API in Zoho? Can you please add some screenshots of the ZOHO setup?
