Authentication

NextSportsAPI uses API keys for authentication. Send your key in the Authorization request header.

Authorization: Bearer YOUR_API_KEY

Example

curl --request GET \
  "https://api.nextsportsapi.com/v1/football/fixtures?date=2026-08-16&league=L7K9Q2R&season=2026" \
  --header "Authorization: Bearer YOUR_API_KEY"

Key handling

Store production API keys in environment variables or a secrets manager.
Use separate keys for development, staging, and production projects.
Rotate keys if they are exposed in logs, source control, client-side code, or third-party tools.
Keep high-volume polling on a backend service so usage can be controlled and cached.

Authentication errors

Authentication failures return a standard error response with an HTTP status code and a readable error object.

{
  "get": "football/fixtures",
  "parameters": {},
  "errors": [
    {
      "code": "auth.invalid_key",
      "message": "The API key is missing or invalid."
    }
  ],
  "results": 0,
  "paging": {
    "current": 1,
    "total": 1
  },
  "response": []
}
