I want to use a webhook to enrich fields on a Lead record in Marketo.
However, I want to have the webhook update our existing fields instead of fields specific to that webhook / enrichment api (even though this seems to be the recommended method from enrichment data providers).
Can I update a field with the webhook response only if that field is blank? Is there any way to build that logic in to the webhook?
It looks like one way around this would be to have a smart campaign checking for certain combinations of blank fields and then calling a certain webhook with a customized response mapping. However, this isn't very efficient as there are many combinations of possible blank fields. Is there a better way to manage this?
