Good morning,
I’m taking “N8N101 Essentials: Your First Workflows” course, and I’m working through section 1.2 of Hand-on exercise:Buikding a sales data pipeline. After following all the steps to configure the http request node step by step, the node gives me the error “Forbidden - perhaps check your credentials?
Authorization data is wrong!”
Having already used these credentials for the exercises in “n8n quickstart” course, how is it possible that I’m getting this type of error? Is it possible that the URL indicated (https://learn.app.n8n.cloud/webhook/course/n8n101/sales-data) is incorrect?
Can someone help me? Thank you
Hi! This is a common stumbling block in the N8N101 course. A few things to check:
1. Re-check the credential type
The n8n101 sales-data webhook uses Header Auth with a specific token the course provides — it is not the same credential as the Quickstart. Reusing a Quickstart credential means the token value is wrong for this endpoint.
2. Confirm the exact header name and value
The credential should be configured as:
- Name:
n8n-course-user-token - Value: your unique course token (shown in the course dashboard / My Account area)
If either the name or value does not match exactly what the webhook expects, you get 403 Forbidden / Authorization data is wrong!
3. Check for whitespace
Copy-pasting the token sometimes adds a trailing space. Try deleting and retyping the token value manually.
4. The URL looks correct
https://learn.app.n8n.cloud/webhook/course/n8n101/sales-data is the right endpoint — no change needed there.
If you have verified all the above and it still fails, try creating a brand-new Header Auth credential from scratch (do not reuse the Quickstart one) and paste the course token fresh. That usually resolves it.
Thanks for your reply.
If I don’t need to reuse the credentials from the previous course, I’ll obviously need to create a new credential. Does the configuration you suggested go in this section or in the node headers? Also, where can I find the token? I thought it was the assessment ID found at the top right of the dashboard. Could you walk me through the steps to configure the new credential and the node settings? thank you
Hello,
Section 1 goes through how to setup the credential with your first hands on workflow. Please be sure to read the section on configuring your credential. This credential will be required for every single call across all three foundations courses.
