Trying to import new contacts and update contact info for existing contacts in zendesk sell

Hi Hanna, 

You sure can, you'd want to use the python requests library to accomplish this. You can find an example of what a request would look like in python here.

Hope this helps!

Hi Hanna,

Sorry I didn't see your edits. You'd want to use the upsert endpoint which can be found at the bottom of this page.

Let us know if you have any further questions.

Thanks, Eric!
