Feasibility & Workaround for Dynamically Passing Campaign ID via OIC Adapter

Hi Team,
We have a requirement to run multiple campaigns at the same time. Once a campaign is activated in Eloqua, we need to trigger an external API to send the segmented customer data along with the "Campaign ID" to downstream engagement channels such as Email, IVR, and ATM.
Additionally, a single customer can be part of multiple campaigns simultaneously.
Below is a sample response payload,
{
Campaign ID : 121
Customer : [
{
Name: Cust 1,
Phone: +9121121212
Email : abc@gmail .com
},
{
Name: Cust 2,
Phone: +9121121212
Email : abc@gmail .com
}
]
}

{
Campaign ID : 122
Customer : [
{
Name: Cust 1,
Phone: +9121121212
Email : abc@gmail .com
},
{
Name: Cust 2,
Phone: +9121121212
Email : abc@gmail .com
