Power Platform Community Forum Thread Details

Hello there,

I am building an app with a Pen Input for signatures. I will eventually save the data from Powerapps to OD4B as a .htm file then, convert it to a PDF.

I am trying to pass the Pen Input image to Flow using a Custom Connector an a Swagger file as described in this video by @Anonymous:

I have double checked my host and base path.

I also updated my host path omitting the :443 as he indicated in this article:

http://www.cleverworkarounds.com/2017/11/13/a-sample-openapiswagger-file-for-powerapps/comment-page-1/

Here is my swagger file for reference:

{
 "swagger": "2.0",
 "info": {
 "description": "Convert the signature of a waiver",
 "version": "1.0.0",
 "title": "WaiverHandler"
 },

 }
 }
 }
 },

}

No matter what I do I cannot get the PenInput.Image to Flow. I have tried to recreate the flow, recreate the swagger file and have recreated the custom connector a dozen times. No dice. Can anyone help me with this?
