Flipkart Marketplace vs Lazada

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.

Lazada's Open Platform gives registered sellers and partners programmatic access to product, order, and seller-performance data across its Southeast Asian marketplaces. Every call must carry an HMAC-SHA256 signature derived from an app key/secret pair rather than a plain bearer token, confirmed live by a MissingParameter error demanding the app_key. Access requires an approved developer application tied to an active Lazada seller account, at no separate charge.
