Configure a Data Extension to Store a Data Action Payload

If you’re using a Marketing Cloud Engagement data action target to enrich a data action, configure a data extension to store the data action payload.

  1. Create a data extension with two attributes: one for storing the subscriber key, and the other for storing the nested JSON payload.
    • Subscriber key
      • Name: Match the Data Cloud object’s field API name
      • Data Type: Match the Data Cloud object’s field data type
    • Nested JSON payload
      • Name: Match the Data Cloud data graph API name
      • Data Type: Text
      • Length: Up to 4000 characters (the length can vary based on your output payload and the number of supported characters in Marketing Cloud.)
  2. For both attributes, select Nullable and leave Default Value empty.
    After creating the data extension, parse the data graph data from the attribute using a supported scripting language in Email Studio.
Example
Example Sample AMPscript to parse the nested JSON payload 
%%[
    SET @NESTEDDG = Concat('[', AttributeValue("WebinarDataGraph"), ']')

    /* Extract root level fields */
    SET @RS = BuildRowsetFromJson(@NESTEDDG, '$.[*]', 1)
    SET @Row = Row(@RS, 1)
    SET @Id__c = Field(@Row, "Id__c")
    SET @PersonName__c = Field(@Row, "PersonName__c")
    SET @TitleName__c = Field(@Row, "TitleName__c")
    SET @LastName__c = Field(@Row, "LastName__c")

    /* Extract nested JSON array pzn_UnifiedLoyaltyBalance__cio */
    SET @LoyaltyArray = BuildRowsetFromJson(@NESTEDDG, '$.[*].pzn_UnifiedLoyaltyBalance__cio[*]', 1)
    SET @LoyaltyArrayRow = Row(@LoyaltyArray, 1)
    SET @totalpoints__c = Field(@LoyaltyArrayRow, "totalpoints__c")
    SET @unifiedindividualid__c = Field(@LoyaltyArrayRow, "unifiedindividualid__c")
