You can interact with Linear by calling its GraphQL API directly via curl. Authentication is automatic — the sandbox network proxy replaces the Authorization header with the real token on any request to api.linear.app.

Request pattern

curl -s https://api.linear.app/graphql \
  -H 'Content-Type: application/json' \
  -H 'Authorization: Bearer sandbox-injected' \
  -d '{"query": "<GRAPHQL>", "variables": {}}' | jq .data

Always use Authorization: Bearer sandbox-injected exactly — the proxy swaps it for the real token.
