Error when fetching data with unique_id – "Please provide the correct Unique ID"

Hi n8n community :waving_hand:,

I just received the Level 1 access email with my unique_id. I’m trying to use it in an HTTP Request node to fetch data, but I keep getting this error:

error: Please provide the correct Unique ID.

Here’s what I did:

  • Added a header parameter → unique_id

  • Value → my actual unique_id from the email

  • Sent the request, but the server still rejects it

:backhand_index_pointing_right: My question:

  • Am I supposed to send the unique_id in headers, or should it go in query parameters / body instead?

  • Or is there a different format required (maybe wrapping it in JSON)?

Would appreciate any guidance :folded_hands:

Thanks,
Zohaib

Hey @ZohaibCodez

Headers:

{
  "unique-id": "your-actual-unique-id-from-email",
  "Content-Type": "application/json"
}

Still not solved. Same error :slight_smile:
error: Please provide the correct Unique ID.

@ZohaibCodez can I see the header name you previously used? And can you try it as a query parameter instead?

Yeah sure . Here i attached the screenshot.

@ZohaibCodez can you please try again checking the following:

Under your Header Auth

Name: api_key ← [Header Auth name]
Value: hIujLoH(7uYG ← (something like this from your Header Auth value in your email)

Under Send Headers –> Header Parameters

Name: unique_id
Value: nfdfdien45fgklfng849gdkdng633j ← (something like this from your Unique ID in your email)

Also, check your URL from Dataset URL in your email.

Could you please check everything again from the beginning to see if any parts were missed? I think that should resolve it—otherwise, you can reach out to their support team at help@n8n.io or reach out to @aya.

Thanks. But issue resolved. The problem is that i have only signed up for only level 1 . For correct working of api, I have to be signed up on both levels of courses. So i signed up also on level 2 course. And issue got resolved.
Thanks all :slight_smile:
