2. Field Mapping

Consulting the documentation for the mock core, we see there are 5 fields of interest to us:

• Name.FirstName

• Name.LastName

• EmailAddresses.EmailAddress[0].ElectronicAddressLines.ElectronicAddressLine[0].AddrLine

• Identification.DateOfBirth

• PersTyps.PersTyp[0].PersonTypeCode

Additionally, we'll need to add the url_path of the endpoint that we're calling on the Mock Core.

Right-click on the create_new_customer Service Request and select Go To > Field Mapping. Click + Add Row 6 times to create 6 empty field mappings.

Five empty Field Mappings

Each of the fields required by the core can be populated using data we received from randomuser.me, so we simply need to set up the mapping between the fields across the two systems.

First, we'll populate all the fields that the core expects. In the field column, copy in the following JSON paths:

Field
Name.FirstName
Name.LastName
EmailAddresses.EmailAddress[0].ElectronicAddressLines.ElectronicAddressLine[0].AddrLine
Identification.DateOfBirth
PersTyps.PersTyp[0].PersonTypeCode
url_path

Now for each field that the core expects, we'll enter the JSON path to the value as it exists in the response from randomuser.me:

Field	Value
Name.FirstName	request_users.response.payload.results[0].name.first
Name.LastName	request_users.response.payload.results[0].name.last
EmailAddresses.EmailAddress[0].ElectronicAddressLines.ElectronicAddressLine[0].AddrLine	request_users.response.payload.results[0].email
Identification.DateOfBirth	request_users.response.payload.results[0].dob.date
PersTyps.PersTyp[0].PersonTypeCode	"individual"
url_path	"/api/integration/fiservdna/person_maintenance"

Notice that while the first four items are JSON Paths into the object returned by randomuser.me, the last item is a static value, as it will always be the same for all users created by this integration.

Finally, fill out str for the Value Type column for all rows.

Five field mappings for the Service Request

We have now transformed the data received from randomuser.me into the format that the mock banking core expects.
