Hi Andy, a team of developers is working on revising the full connector development education path including certifications.
The focus will be not only on specific integrations, but also on best practices, improving user experiences, practical use-cases. Due to this full revision it is not yet possible to provide an agenda.
Currently we are working on a more detailed explanation on the internal logical flow when using specific communication methods (e.g. what processes are used) and aim to have videos on this early Q2 2021.
