Issue with product sync with splashsync

I have a dolibarr setup.
I have a wordpress website in which I am using woocommerce.
I am using splashsync to synchronize dolibarr and wordpress.
While synchronizing, it was displaying error in spashsync like ‘Local user not found’. So asked to splashsync support. They replied

Your Dolibarr setup is not complete… Please select an user for API requests.

Please let me know how can I do this?

Thank you
