Uppercase Authentication
Authentication profile for the uppercase storefront's machine surfaces, captured from the OIDC discovery and OAuth authorization-server documents served on uppercase.co.in (Shopify customer accounts, issuer https://shopify.com/authentication/67539140858). Customer-facing API and MCP access uses OAuth 2.0 authorization-code with PKCE (S256) plus refresh tokens and JWT bearer grant; unauthenticated read-only browsing of product and collection JSON is documented in /llms.txt. There is no first-party developer key program — auth is the Shopify platform surface on the store's own domain.
Uppercase secures its APIs with oauth2 and openIdConnect across 2 declared security schemes, as derived from its OpenAPI definitions. OAuth 2.0 is offered via the authorizationCode flow(s).
