Every NexLev API request must include your API key. There is no separate OAuth flow — a single key authenticates all endpoints documented in the NexLev API reference.
Getting an API Key
- Sign in to your NexLev dashboard
- Go to Create API Key
- Copy the generated key — it is shown once and cannot be recovered later, only regenerated
Request Header
Include your API key in the Authorization header of every request:
Authorization: Bearer YOUR_API_KEYExample with curl:
curl "https://prod.dashboard.nexlev.io/api/external/channels/about?id=UCX6OQ3DkcsbYNE6H8uQQuVA" \
-H "Authorization: Bearer YOUR_API_KEY"Managing Your Key
- Rotate or revoke: Manage API Key
- Monitor usage: The same page shows your remaining quota — see Rate Limits & Quota for how quota is calculated.
Unauthenticated Requests
Requests without a valid Authorization header receive a 401 Unauthorized response:
{
"error": "Unauthorized",
"details": "Missing or invalid API key."
}
