Extrahera bundna data och spara dem i en strängvariabel

Med den här funktionen kan du inkludera skickade data i e-postmeddelandet. Det anpassade processsteget extraherar bundna data från den adaptiva formuläröverföringen och fyller i en variabel av typen sträng med data. Du kan sedan använda den här strängvariabeln för att infoga data i din e-postmall.
I följande skärmbild visas de argument som du behöver skicka till det anpassade steget

Följande parametrar

• data.xml - Den fil som innehåller skickade data. Om formatet är json kan filens namn vara data.json

Det anpassade processsteget extraherar sedan bundna data och lagrar dem i variabeln skickadDataString som definieras i arbetsflödet
