As we know, adobe have the email, sms, DM, facebook channel to delivery, but I want to build a new channel of delivery, is there any document I can reference to create it? what I should build in schemas,forms or js? thanks!
Can you please specify which channel do you want ?
The channels are activated based on pre-defined packages which we can install in Campaign . I do not think you can build a channel for which a default package is not present .
