We are not Eloqua experts and we are trying to 'integrate' key activities of our online registration system using the External Asset, External Activities framework. We have created an External Asset Type (let's say Tradeshow) that has four External Activity Types (Invited, Registered, Declined and Cancelled). We have been able to upload a spreadsheet which successfully attributes External Activities to Contacts within a Campaign. We are now trying to use the API 2.0 to create an External Activity for a Contact. We have submitted what seems to be a properly formatted request and receive what appears to be a properly formatted response. However, the External Activity is not apparent on the specified Contact within Eloqua. Any ideas? Has anyone had similar difficulty with the API method?
POST /api/REST/2.0/data/activity
