Before connecting Deliverr with SellerChamp, make sure your marketplaces are disconnected from Deliverr.
The reason why we want to do so is to avoid sending duplicate orders for fulfillment to Deliverr.
Here is how you do it:
Go inside your Channels page in Deliverr and click on the selling channel.
On the next page, click on the Disconnect Channel option
Now remain logged into Deliverr and lets establish a connection to SellerChamp.
