Using WebAccess activities response body to next WebAccess activities request body(Azure Data Factory)

[Alert] Web Access activity can’t handle more than 4MB. [Microsoft’s web site]

Web2 Settings

Method：POST

Body： @concat(‘{ “records”:’, activity(‘Web1’).output.records, ‘}’)

Thre result of Web1 Activity is not a simple strings. You can get value by using “activity(‘Web1’).output.records”.

But it is an array object and ommited the first

{
     "records" : [

And the last

]
}

So. You can build string by using concat function.
