ComputerVisionAPI V2 Method OCRV2 and OCRTextV2 missing parameters

I'm trying to use the ComputerVision API with the OCRV2 or OCRTextV2 as the original OCR and OCRText methods are no longer available (unless I'm missing something).

The issue I'm having is that the API documentation for OCRTextV2 gives somes parameters:

Required Parameters
Image Source
Source of the image - either included or by reference url.

But the PowerApps web studio gives me different ones and there is no way to insert the image in the request:
See First image

But it seems to work fine with DescribeContentV2
See second image.

Any idea what is wrong ?

Re: ComputerVisionAPI V2 Method OCRV2 and OCRTextV2 missing parameters

Hi @matremblay ,

Do you want to use the ComputerVisionAPI.OCRV2() function and the ComputerVisionAPI.OCRTextV2() function within your canvas app?


Based on the issue that you mentioned, I have made a test, and the issue is confirmed on my side. Currently, within PowerApps, when you use ComputerVisionAPI.OCRV2() function or the ComputerVisionAPI.OCRTextV2() function, there is no place to provide the Image argument (second argument).

I think this issue may be related to the Computer Vision API (the Image parameter is not be exposed within OCRV2 action and OCRTextV2 action). Currently, within PowerApps, I afraid that there is no way to achieve your needs.


If you would like this feature to be improved within PowerApps, please submit an idea to PowerApps Ideas Forum:


As an alternative solution, you could consider achieve your needs using Microsoft Flow. I have made a test on my side, please take a try with the following workaround:8.JPG


In addition, you could also consider take a try to create a custom connector based on Computer Vision API within your app to achieve your needs. Please check and see if the following blog or video would help in your scenario:


If you capture the picture within your canvas app using Camera control instead of Add Picture control, I think the following video would also achieve your needs:

Re: ComputerVisionAPI V2 Method OCRV2 and OCRTextV2 missing parameters

I see, IO will post a suggestion to try to push them to update the API.

One thing, I'm not sure how to send the captured image from my Powerapp to the Microsoft Flow then trigger it, then retrieve the informations. Can you point me to the right direction ?
