API Key Is Denied

Your NexLev API key returns access denied in n8n or the NexLev API. Keys belong to the account that created them; revoke the old key and create a new one on your paid account.

What you see

An API key you use for n8n or the NexLev API returns "access denied", or acts as if you have no plan.

Why it happens

API keys belong to the NexLev account that created them. A key made while you were signed in to another account doesn't carry your paid plan.

Each account can have only one active API key at a time, so you need to revoke the current key before you can create a new one.

How to fix it

Step 1: Sign in to the dashboard with the account that paid

Go to dashboard.nexlev.io and click Continue with Google. What happens next depends on how many Google accounts are signed in to your browser profile.

Scenario 1

Only one Google account is signed in to your browser profile

Clicking Continue with Google signs you in to the dashboard with that account straight away. You won't see an account picker.

Make sure that account is the one you bought NexLev with. If it isn't, add your purchase account to the browser profile, then sign in again and you'll get the account picker from Scenario 2.

Scenario 2

Several Google accounts are signed in to your browser profile

Google asks you to Choose an account. Pick the account you bought NexLev with.

Step 2: Check the dashboard shows the plan you bought

Once you're signed in, check the plan shown next to the NexLev logo in the top-left corner, and in your profile menu in the top-right corner.

The NexLev API and n8n need NexLev Pro or the n8n Pro package.

If you don't see the plan you bought, you're signed in to a different account. Sign out and go back to Step 1.

Step 3: Open Manage API Keys

In the dashboard sidebar, click Nexlev API.

Step 4: Revoke your active key

Your keys are listed with their status. Only one can be Active; older keys show as Revoked.

Click Details on the Active key.

If you don't have an active key, skip to Step 5.

Step 5: Create a new API key

Go back to the Nexlev API overview page and click Create API Key.

Create API Key

Step 6: Replace the old key

Use the new key everywhere you used the old one:

  • n8n: open your NexLev credential and paste the new key into the API Key field. See Configure Authentication in the n8n Quickstart.
  • NexLev API: send the new key in the Authorization header. See Authentication.
