    hello Darwood 

     

    I think you have done most of the hard work to get the authentication and connection done

     

    Now for Web Activity Output Handling
    • Use a Set Variable activity to capture the Web Activity response
    • Configure the variable to store the complete JSON output


    Create Copy Data Activity Setup
    • Create a dummy source query using a Fabric Datawarehouse connection
    • Use the “Additional Columns” section in the source to define your output schema
    • Configure the destination as the Lakehouse Files section
    • Map the fields from your variable to the destination columns

     


    check this discussion it will be helpful

    If this helps. Please accept the solution 

     

    Thanks

Thanks for the suggestion nilendraFabric 

I am getting a data type error on the Set variable activity though when I try and run the Data Pipeline. I have tried using a string or array data type and I get the same sort of problem.

 

The settings for the Set variable activity are:

  • Variable type: Pipeline variable
  • Name: devicesJson
  • Value: @activity('Devices').output (this is the name of the previous Web activity API call)

 

"The variable 'devicesJson' of type 'Array' cannot be initialized or updated with value of type 'Object'. The variable 'devicesJson' only supports values of types 'Array'."
