Go to WooCommerce > Settings > Advanced > REST API
In the description section, title it 'deliverrKey'. The exact name does not matter, as long as you know this key is associated with Deliverr.
Make sure that you give it both read and write permissions. If both permissions are not granted, then simply delete the key and create a new one.
Click Generate API key to continue.
Copy and paste the Consumer key and the Consumer secret into Deliverr so that we have access to your WooCommerce account.
If you navigate away from this page before copying the keys, then they will not be visible again. Simply delete the key and create a new one.
Copy and paste the URL of your store, without the https:// prefix or the trailing slash. For example, our test store's URL is: https://xxxxxxxx.wpcomstaging.com/ so in the text field we would put in xxxxxxxx.wpcomstaging.com
