Hi, glad to join this group as my company get more demanding for complex automations haha.

I am hoping someone can help me work out if I can use Process Builder to add all contacts from an account to a campaign based on an Opportunity being won. Not ideal for a solo admin automation novice. :)

I have worked out the criteria for won...

But having problems working out how to add them all.

At a minimum to add those who are Contact Roles - but ideally all that are listed as contacts in an account. 

Immediate Action: Create Campaign - record type: Campaign Member.

Field: Campaign ID, Type ID, Value X

Field: Status, Type Picklist, Value X

Then how do I reference Account to bring in multiple contacts??

The idea is that I can then use this campaign to send out Onboard comms using Pardot. 

Hopefully can do this without using flow, as even more of a novice at that, 

Thanks in advance!
