Hey @makechinafreedom,

For your URL are you sure you are using https://internal.users.n8n.cloud/webhook/custom-erp and not something else?

3

the url I get for the email when I join the coure. here it is n8n Course Redirect

4

It should be the URL mentioned in the training not the one in the email, Try using the other URL and you should be all good.

In the left panel, select:

    Authentication: Header Auth
    URL: https://internal.users.n8n.cloud/webhook/custom-erp
    Options > Add Option > Split Into Items: toggle to true. This option will output each element of an array as its own item.
    Headers > Add Header:
        Name: unique_id
        Value: your_unique_id

Hello. I need help too.

Error: Forbidden - perhaps check your credentials?

Authorization data is wrong!

403 probably. Is there a possibility that my unique_id is expired?

Tks for the help.
