Add your largest Sales Channel integration first. Go into Integrations window and choose your Sales Channel from the available list to the right and click on it.
In the window that has just opened you will need to type in your credentials to the left and to the right you will find the Integration Guide (these are unique for every integration), you can always press on the “Detailed Instructions” link for a step-by-step guide.
Once all the information is filled press Connect. If you entered everything correctly the integration will appear in the “Connected Integrations” menu on the left side.
After 10 minutes all of your Sales Channel inventory will appear inside Multiorders Inventory page.
