Troubleshoot

I don't have, or forgot, my API keys for configuring Hornbach

You can generate new keys inside your Hornbach seller central. If you don't know where to find them, please contact your account manager at Hornbach.

Products are shown double in my Hornbach account, what now?

This normally happens when you've changed the SKU's that are being used. In this way, products are created again, and the old ones will remain in your dashboard which leads to double products. 

The way to solve this is to remove the products with the 'old SKU's. If this happened with a lot of products, you can empty your inventory at Hornbach and request our customer success department to refill your inventory by re-sending the offers.
