Digi-Key vs Lazada

Digi-Key's api.digikey.com gateway runs a genuine OAuth2 flow: its authorization endpoint rejects requests missing a client_id, and resource endpoints additionally require a client-specific header, ruling out simple API-key auth. Access to product, ordering, and barcode data is free with per-product rate limits, and CORS is explicitly configured, echoing the request Origin on both live calls and OPTIONS preflights.

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.
