Merge fields

A Merge field is a Flow variable that stores the output of the Step. In other words, if the Step in the Flow returns some result that should be used later in this Flow, it uses this Merge field to pass the value from one Step to another. There is no limit to the amount of information a Merge field can store. However, we recommend storing only the necessary (minimum) amount, as larger volumes of information will cause slower Flow execution. If you need to pass on large data volumes, try storing them in tables and then collecting them from there.

TIP

If the Flow passes the same Step again (for example, using the Go to Step), the Merge field data will be overwritten.
