Flipkart Marketplace vs Rappi

Flipkart's Marketplace Seller API issues OAuth2 bearer tokens through either a client-credentials or an authorization-code grant, for self-access and third-party seller applications respectively. Its own documentation explicitly requires HTTPS and states plain HTTP requests are rejected, with tokens typically valid for around 60 days before they must be renewed.

Rappi's public API lets approved merchant partners manage store menus and orders across its Latin American on-demand delivery platform. Access requires a formal partnership and uses OAuth2 — Authorization Code with PKCE for partner-facing flows, plus Auth0-issued bearer tokens for machine-to-machine calls — confirmed live against its login/token gateway. Each country Rappi operates in runs its own regional API host.
