We are on a starter plan of Zendesk. And we have an opencart store.
What we would like to do is that, our opencart store customers don't need to log on or sign up on our zendesk page, but using their existing account in our store.
You can easily realize this job if you know how to use the API. Zendesk provides Remote authentication API function.
We are looking for a long time cooperation worker who can do a great job in short time.
