Translate informatica Documentation into REST API Call (Postman) - postman

Question

I am working on importing data into Informatica Reference360 and struggling to interpret documentation to construct an API call in POSTMAN.
Here is the example they are giving
POST https://use4-mdm.dm-us.informaticacloud.com/rdm-service/external/v1/import HTTP/1.1
Content-Type: multipart/form-data; boundary=6o2knFse3p53ty9dmcQvWAIx1zInP11uCfbm
IDS-SESSION-ID: XXXXXXXXXXXXXXXXXXXXXX
--6o2knFse3p53ty9dmcQvWAIx1zInP11uCfbm
Content-Disposition: form-data; name=file; filename=import-code-values.csv
--6o2knFse3p53ty9dmcQvWAIx1zInP11uCfbm
Content-Disposition: form-data; name=importSettings
Content-Type: application/json;charset=UTF-8
{
"delimiter":"COMMA",
"textQualifier":"DOUBLE_QUOTE",
"codepage":"UTF8",
"dateFormat":"ISO",
"containerType":"CODELIST",
"containerId":"9ab3201990a54dcdc86f54cf",
"startingRow":null
}
--6o2knFse3p53ty9dmcQvWAIx1zInP11uCfbm--
The parts I do not understand:
what is this for: boundary=6o2knFse3p53ty9dmcQvWAIx1zInP11uCfbm.Should I put it in header as well?
What is this and where should I use it (are these two alternatives and only one should be used)?
--6o2knFse3p53ty9dmcQvWAIx1zInP11uCfbm
Content-Disposition: form-data; name=file; filename=import-code-values.csv
--6o2knFse3p53ty9dmcQvWAIx1zInP11uCfbm
Content-Disposition: form-data; name=importSettings
Content-Type: application/json;charset=UTF-8
...
--6o2knFse3p53ty9dmcQvWAIx1zInP11uCfbm--
How should I pass the actual file for import, should it be in body (form-data)?
If so which parts of the API payload should be in raw and which in form-data?

Answer 1

Basically, your POST request requires 2 parts:
1.Upload file csv
--6o2knFse3p53ty9dmcQvWAIx1zInP11uCfbm
Content-Disposition: form-data; name=file; filename=import-code-values.csv
2.Json object
--6o2knFse3p53ty9dmcQvWAIx1zInP11uCfbm
Content-Disposition: form-data; name=importSettings
Content-Type: application/json;charset=UTF-8

Answering my own questions:
what is this for: boundary=6o2knFse3p53ty9dmcQvWAIx1zInP11uCfbm.Should I put it in header as well?
this is generated automatically in the header by postman
What is this and where should I use it (are these two alternatives and only one should be used)?
both of them should
If so which parts of the API payload should be in raw and which in form-data?
everything should be input in body - form data
