Getting data through external API activity with varying amount of data in the response

[bartosz_markowski]

Hello,

I'm trying to use external API activity to read some data from the endpoint. The issue is that response mapping might be different depending of how many rows of data will there be in the response table.

So, if there are 2 records in the response, it will look like this:

{
   "message":"OK",
   "total":1,
   "page":1,
   "page_size":100,
   "payload":[
      {
         "title":"abc1",
         "nickname":"xyz1",
      },
      {
         "title":"abc2",
         "nickname":"xyz2",
      }	  
   ]
}

and if there will be 3 records it will look like this:

{
   "message":"OK",
   "total":1,
   "page":1,
   "page_size":100,
   "payload":[
      {
         "title":"abc1",
         "nickname":"xyz1",
      },
	  {
         "title":"abc2",
         "nickname":"xyz2",
      },
	  {
         "title":"abc3",
         "nickname":"xyz3",
      }
   ]
}

and so on.

So I can't specify a strict format in "Outbound mapping tab", thus "Column definition tab" is also not prepared. 

Can I somehow configure External API activity for this case to accept varying amount of data in the response?
