# Loop Block

A Loop Block iterates over the items in a data array, enabling the Actions within it to repeat for each item. The array input to the Loop Block is processed so that each iteration receives only one item in the array.

            <p>Configurable Key/Value pairs to be available to subsequent Integration
              Procedure steps. Enter a Key and set the Value to the response of an Action
              within the Loop Block. The value can use merge field syntax, percentage
              signs on either side of the node name, to access that response. By default,
              if no Key/Value pairs are specified, a response of <code>{ "success": "OK" }</code> is returned for each
              item processed in the array.</p>
            <p style="margin-bottom:0;">Use this property with care. It returns the data you request for every
              iteration. If the Loop Block iterates 1000 times, it returns 1000 responses.
              This property is most useful for debugging or returning a limited
              dataset.</p>
