The JSON Deserialize converts a string of JSON data into its respective Decisions data object type. The data object type is picked via the Type drop-down, and the string is input via the String to Deserialize Input. This can help convert data that has come into a Flow via REST call into data that Decisions can use.
Prerequisites
