Documented steps
Railway's public API is GraphQL at https://backboard.railway.com/graphql/v2 — there is no REST equivalent for these ops.
Generate a token in the dashboard (Settings > Tokens) as an account, workspace, or project token.
For account/workspace/OAuth tokens, send an HTTP Authorization header with a Bearer credential.
For a project token, send the header 'Project-Access-Token: <PROJECT_TOKEN>' instead of the Authorization header.
Send POST with Content-Type: application/json and a JSON body {"query":"..."}.
Test auth with: query { workspace(workspaceId: "<ID>") { name id } } using a workspace token, or query { projectToken { projectId environmentId } } using a project token.
Project tokens use the Project-Access-Token header; account/workspace/OAuth tokens use an Authorization Bearer header — mixing them returns auth errors.
The endpoint is backboard.railway.com/graphql/v2, not api.railway.com.
Never hardcode tokens; pull from env or a secret manager.
The GraphQL playground at https://railway.com/graphiql is useful for exploring the schema before scripting.
