Hello @alepeculier,
You can do this by creating a Javascript that overload the native "processDeliveryPart" function.
Your Javascript should look like this :
//-------------------------------------------
//Overload Adobe Campaign Delivery Connector
//-------------------------------------------
function processDeliveryPart(deliveryPart){
for each ( var msg in deliveryPart.message ){
// do what you have to do with your message. i.e call Batch API to send message
}
}Then you should create a new External account for this channel. In the "Connector" part on this External account you specifie the JS that you've created previously.
That's the general idea.
