[Forums] How to send multiple values as input parameter

You could write all this data to an entity with enough identiying information that the action knows which records to process and once processed delete them from the entity.  This would allow an unlimited number of elements. Another way would be to use the built-in List actions (like ListAppend) to create the list of entries and pass the list as a single parameter.  See the help on ListAppend for details.

Hope this helps,
