Right now, if you have a direct API integration for lead flow, the original source drill down 1, will show "API." That's it. You can't change it to show which integration partner its coming from and they can't either.
My suggestion would be to allow the the hubspot user to map that integration similar to how you can do with it Hubspot forms or how other hubspost fields have internal ID's. the purpose is, so you can trigger custom workflows from specifc lead sources and or run reports on which one of your API partners is sending you the best leads.
We could set a property valye in Original lead source, but this a field that can be manually selected and or changed. There will be too many errors and "dirty data."
With this type if data, as a sales leader, you can feed the right leads to the right people on your team, as well as feed data back to your marketing as to which "channel" of leads is closing better and or producing a higher quality customer.
