Eloqua批量REST API提供序列化错误

Question

I am trying to make bulk REST API call to import data to Eloqua. I am able to make call to GET, But POST gives me "400- There was a Serialization Error".

This is first step to get response for creating import definition from Eloqua Bulk REST.

URL: /api/bulk/2.0/contacts/imports

Headers:
Authorization: valid oAuth2 token
Content-Type: application/json

Body:

{  
   "name": "AppSource Test",
   "fields": {  
      "firstName": "{{Contact.Field(C_FirstName)}}",
      "lastName": "{{Contact.Field(C_LastName)}}",
      "emailAddress": "{{Contact.Field(C_EmailAddress)}}"
   },
   "identifierFieldName": "emailAddress"
}

Documentation also doesn't have details about this.

Am I missing something?

Answer 1

Change Body content type to "raw"

Explanation: Eloqua expects the data it receives be in "raw" format. Although Header says Content type json, Setting Body as "raw" works.
