To connect your Tokopedia shop, click Settings on the top navigation and then Connect button for Tokopedia account. You will then be prompted to input your Tokopedia shop domain. You can find your Tokopedia shop domain from the URL of your tokopedia shop homepage (ie: tokopedia.com/<myshopdomain>).
After you submit your Tokopedia shop domain, kindly wait for an email from Tokopedia that Osco is requesting access to manage your Tokopedia shop. Accept the request, so Osco can complete the account connection. This whole process might take 12-24 hours.
