Altair GraphQL Client is a customizable, cross-platform GraphQL Client for all platforms. It is built with Electron and Angular.

Getting started

Once you have client installed you will need to load a GraphQL schema. You can do this by clicking the "Docs" button at the top right corner and then clicking the "..." button and selecting the "Load schema" option.

How to load schema How to load schema with different extension

You can download Lumar GraphQL API schema from Public schema page. Optionally save the schema file with .gql extension instead of .graphql extension as that is the default extension for Altair.

Set the API url to and method to POST.


Once you have the initial setup done, you will need to obtain session token from Lumar API. You can do this by following the steps in Authentication page. You will need to use API access tokens to generate session token.

Creating session token

When you have obtained the session token, you can set it by selecting "Set Headers" option on the left sidebar and setting Header key as x-auth-token and header value as the session token you obtained.

Set x-auth-token header in Altair

If you have done everything correctly, you should be able to make authenticated GraphQL queries and mutations. To test authentication you can send

query AltairCheckingAuth {
me {
