How to Associate a Tag with a Lead Source

How do you Associate a Tag with a Lead Source?

What do you mean by that?

If someone has a Leadsource set to “Tradeshow” - are you wanting to apply a tag to that contact record called “Tag → Tradeshow”. Is this what you mean ?

Out of the box, I can’t think of a direct way but we have designed webhook responses in the past that check fields and raise tags based on their content.
