How to Parse JSON an URL Image

Hello every body,

I have a problem, where I want to save a photo label to a SharePoint Document. I got the photo of the label using the Labelary API by filling in a few parameters so that it fits my needs. But I'm confused about exporting it to SharePoint Document, because when I press a button, the result from Parse JSON only produces the same URL instead of base64 code.

Here's my On Select properties on my button:

Set(varImageJSON, JSON(Image2.Image, JSONFormat.IncludeBinaryData))

My Image properties on my Image:

"http://api.labelary.com/v1/printers/8dpmm/labels/1.9685x0.984252/0/%10CT~~CD,~CC%5E~CT~%20%5EXA~TA000~JSN%5ELT0%5EMNW%5EMTD%5EPON%5EPMN%5ELH0,0%5EJMA%5EPR4,4~SD15%5EJUS%5ELRN%5ECI0%5EXZ%20%5EXA%20%5EMMT%20%5EPW400%20%5ELL0200%20%5ELS0%20%5EFT14,38%5EA0N,28,28%5EFH/%5EFDEmployeeID:%5EFS%20%5EFT14,126%5EA0N,28,28%5EFH/%5EFDName:%20%5EFS%20%5EFT14,176%5EA0N,28,28%5EFH/%5EFDPosition:%5EFS%20%5EFT302,106%5EBQN,2,4%20%5EFDLA,0715%5EFS%20%5EFT111,84%5EA0N,28,28%5EFH/%5EFD0715%5EFS%20%5EFT114,126%5EA0N,28,28%5EFH/%5EFDJohanness%5EFS%20%5EFT114,176%5EA0N,28,28%5EFH/%5EFDMarketing%20Manager%5EFS%20%5EPQ1,0,1,Y%5EXZ"

I hope you guys can help me. I will really appreciate. I also attached some photos for help. Thanks.

Take a look at this video by Shane Young. He walks through the process.

@Pstork1 Thank you very much for your fast response. Putting aside the first to upload to Share Point Documents, now I only need the base64 code from the image with the URL.

But the method used to get the base64 code is the same as Shane Young's, but I don't get a value like:
"data: image / png; base64, {The Code}"
, but only returns a URL (not a blob) value like:
"http://api.labelary.com/v1/printers/8dpmm/labels/1.9685x0.984252/0/(EncodedZPLCode} ", below I attached a gif to show my problem. Why did this happen?, please help me. Thank you.

Sorry, that reply was actually posted to the wrong thread.

The problem is that you are setting the Image property to make a call to a REST service and the image that is returned is displayed in the image control. Its the JSON that is returned that you actually need to be able to parse. But since you are calling an API to get it that isn't stored in the control. But if you pass that API to a flow the flow can invoke the REST call and will get back the resulting IMAGE JSON. You can then parse it and save it as a document. Here's a screenshot of a simple test with your sample API

And this is what the return values look like in flow.

The $content is the base64 encoded file contents of the image. To save that as a file in OneDrive use the following formula

base64ToBinary(body('HTTP')?['$content'])

Thank you very much @Pstork1 for your help, sorry for my slow response but finally I can modify it, so I can print the image without having to save it first on One Drive or Sharepoint Document, by using 2 HTTPs Connector.
