Unable to retrieve custom connector processed output


I have created a custom connector and specified an already existing API which processes data and responses in JSON form which includes personal info. But I am not getting the output in my Google spreadsheet.


I have not used any swagger file and not aware if any changes are needed from my end.


Thanks & Regards

Re: Unable to retrieve custom connector processed output

Hi @Harmanpreet,


Could you please share a clear screenshot of your flow's configuration?

Further, could you please show more details about the JSON data that your custom connector returned?


Please check if you have provided proper Dynamics content from your custom connector within the "Insert row" action of your flow. If you want to retrieve data from a JSON data within Microsoft Flow, I have made a test on my side, please take a try with the following workaround:

  • Add a Flow Button trigger.
  • Add a Compose action, Inputs field set to following JSON data:
"ClassName":"Computer 131",
"TeacherName":"Andy Huang",
  • Add a "Insert row" action of Google Sheets connector, specify File and Worksheet, ClassName field set to following formula:

TeacherName field set to following formula:


TeacherEmail field set to following formula:


Note: The ClassName, TeacherName and TeacherEmail are keys within above JSON data that I provided. On your side, you should type the following formula to reference value from the JSON data that your custom connector returned:

The flow works successfully as below:2.JPG

Re: Unable to retrieve custom connector processed output

I have tried fetching the output in Google sheet using expressions but didn't receive any. Below is the flow Configuration with output 



My custom connector generates Json with personal information after getting data from Gmail attachment. The output generated after processing and the data send to insert row is display as:


Data received in Insert row action:



Receiving null values in all fields even if mapped dynamically.
