Authentication

An unauthenticated user can use only a handful of public mutations and queries. To gain more access, session token needs to be created and used.

Creating API user key

To generate API user key you can do that at Analytics Hub or after loging into API you can use GraphQL API.

Mutation

mutation GenerateUserKey {
  createUserKey {
    id
    secret
  }
}

Response

{
  "data": {
    "createUserKey": {
      "id": "TjAwN1VzZXJLZXkxMzI",
      "secret": "2199800d3dabcda4f96a36f0e410ec096aa5f1b59cad10b082cf779edff8541495245300"
    }
  }
}

Using session token

After signing in you will receive session token that will be valid for 30 days. To authenticate requests to the API send session token in HTTP header x-auth-token value.

curl -H "x-auth-token: <session token>" -XPOST https://api.lumar.io/graphql -H "Content-Type: application/json" --data-raw '{"query": "{version}"}'

Passing invalid session token will result in 401 error.
