Building Mapper Logic

When making edits in a workshop, one option is to manually edit the Mapper logic. Currently, Lume supports the below manual edits:

• One to one
• Default
• Lookup Table

​

Structuring the mapper logic

To make manual edits, you submit the edits to the mapper property in Run Workshop. Learn more in the Edit Mapper Guide.

Edits are made on a per target property basis. Thus, the manual edit payload will be a list of objects, where each object has two parent keys:

1. targetField, which is the target field the mapping edit will be applied to.
2. transformation: the transformation to be applied for this target field. Below are the options on how to build the transformation payload

• 1-1 Extract
• Default
• Lookup Table

{
   "targetField": "internal_id", // target field transformation is being applied to
   "transformation": {
       "extract": "id", // source property to extract one-to-one mapping to
   }
},
