CiviDiscount gives an easy way to say, "Members get a lower price on a certain event", but I have the opposite situation - "attendees of a certain event get a discount on a membership". Can anyone tell me how to do this?
It seems like I should be able to use the "advanced API filter" to find event attendees - but I can't find any examples of how to use that option.
Would using the Group Based Pricing extension be an option? You could then in theory create a smart group for those contacts that have attended the event and use that group in the price configuration?
I think the advanced api just allows you to add fields that would apply to contact.get api - e.g we use it like {"custom_67" : "Retiree"}
Would this "Event Additional Signup" extension do the job: https://civicrm.org/extensions/event-additional-signup ?
If 'Participant' is allowed as an 'entity' in the entity box, {"event_id": "nn"} where nn = event_id of the event whose participants should get a discount seems like it should work w/out your having to put attendees into a group
