How can I create an API request after receiving a webhook?

Hello everyone,

I would like to create a Shopify API request after I receive a webhook on my app, but I do not have the access token to make it and the loadCurrentSesssion method is returning undefined.

Basically, the idea is to add a tag to the order after it is fulfilled, that’s why I would like to consume the Shopify Orders API.

Thanks in advance for any help.
