I am fairly new to the Eloqua API and was wondering if anyone could help me out in the task I'm trying to complete. I've made a custom form on our website that has fields for First Name, Last Name, Email, and Phone. Once someone fills out this form, I want to submit the data to Eloqua using the API to start this person in an already created campaign. In order for this to work, do I need to create a contact using the Eloqua API first with this person's information before being able to start them in the campaign? How do I go about starting someone on a campaign using the API?
Thanks for any help you can provide!
