Hi @1982luca - both of these integrations are pretty complex and I would recommend using Adobe Consulting or a competent Adobe Solution Partner. I have done both of these and even with the help of the Adobe Pipeline/Triggers integration team it was a struggle to implement properly as the documentation didn't match the reality. Not sure if this has since been rectified. Definitely try to work with someone who has done this successfully before.
If you work with Consulting or a partner, they should be able to liaise with TechOps on your behalf. Otherwise raise the ticket in the Support area of the Experience Cloud admin interface.
