Tool to retrieve a Contentful Management API (CMA) access token. Use when making CMA calls to ensure valid authorization.

Execute a GraphQL query using Automatic Persisted Queries (APQ). APQ reduces bandwidth by sending only a SHA256 hash instead of the full query text after initial registration. Workflow: 1. First request: Include both sha256_hash and query text to register the query 2. Subsequent requests: Send only sha256_hash and variables - the server uses the cached query Common errors: - PersistedQueryNotFound: Query not cached; include the full query text - PersistedQueryMismatch: Hash doesn't match query text; recompute the hash - UNKNOWN_SPACE: Invalid space_id or access_token for the space
