Amazon Seller Onboarding Simplified with KYC & GST APIs

Amazon Seller Onboarding Simplified with KYC & GST APIs

Amazon is not just the world’s largest online marketplace but also a technology powerhouse that continues to shape the future of commerce through intelligent automation and seamless user experiences. Founded by Jeff Bezos in 1994 as an online bookstore, Amazon has since evolved into a global leader in e-commerce, cloud computing (AWS), and logistics.

In India, Amazon operates one of the country’s largest online marketplaces, onboarding thousands of new sellers each month to keep pace with the growing demand for e-commerce. With this rapid growth, the need to streamline and scale seller onboarding became a critical priority.

CHALLENGE

Manual Onboarding Slowed Seller Growth

With thousands of new sellers signing up each month, Amazon faced the complex task of managing KYC and GST verification at scale. Manual checks were time-consuming, error-prone, and often led to onboarding delays or drop-offs. Ensuring full regulatory compliance while offering a smooth, seamless experience to sellers was becoming increasingly difficult, especially during peak onboarding periods.

SOLUTION

Real-Time KYC & GST Verification with Sandbox APIs

To address these challenges, Amazon integrated Sandbox’s KYC and GST APIs into its seller onboarding workflows. With a single API call, Amazon is now able to fetch GST details directly from the GSTN, perform real-time PAN, and auto-populate seller profiles with verified data. This eliminated manual intervention, reduced documentation errors, and created a seamless, frictionless onboarding experience for sellers. Sandbox’s API infrastructure enabled Amazon to scale its operations effortlessly without compromising on accuracy or compliance.

RESULTS

Faster Onboarding and Stronger Compliance

By integrating Sandbox’s APIs, Amazon reduced seller onboarding time by over 80%. Real-time data validation enabled complete regulatory compliance while significantly lowering drop-offs caused by verification delays or mismatches. Even during peak onboarding periods, Amazon was able to approve sellers instantly, delivering a consistently smooth experience for both internal teams and new sellers.
