JSON mapping for special characters

Updated on April 6, 2022

Pega Platform uses property qualifiers to map JSON data to properties in the data model that is generated from REST integration. Navigate to the Advanced tab of a property to see the Property Qualifiers section. The Qualifier field contains the standard pzExternalName qualifier for the property, and the Value field contains the JSON field name. Property qualifiers enable the system to handle JSON field names with special characters that are listed in the pyInboundIdentifierEncoder decision table.

Tip: If your system does not have records generated by using the REST integration wizard and the data model has been created manually, you can set the value of the dynamic system setting Pega-IntegrationEngine/json/legacyMapping to "true". Setting this value allows the system to use the legacy pyInboundIdentifierEncoder decision tables to map special characters in JSON field names to Pega properties.
