A robust Instacart proxy mesh combines diverse mobile ASNs and residential IPs distributed across urban and suburban ZIP codes. This infrastructure ensures accurate geolocation emulation, capturing retailer-specific fees, item availability, and localized promotions. Sticky sessions are vital for cart continuity—preserving delivery options, store assignments, and shopper preferences throughout the simulated purchase flow. Proxy rotation should occur between city clusters, maintaining a low request footprint per node to avoid detection. With proper automation scripts, teams can track platform behaviors in near real time, identifying trends in delivery delays, pricing variability, and product substitution.
