Bank of America Amps Up In-App Experiences
Article Summary
Bank of America cut their mobile app response time in half. Here's how they did it with a simple API consolidation strategy.
Adobe's Vinay Sodha breaks down how Bank of America partnered with Adobe consulting to overhaul their mobile personalization using Adobe Target's RESTful APIs. This case study shows how architectural decisions directly impact user experience at scale.
Key Takeaways
- Consolidated multiple API calls into single request using REST API v2
- iPhone response time dropped from 1.5s to 0.75s (50% faster)
- Adobe Target RESTful APIs enabled server-side personalization across mobile
- Four prominent home screen tiles previously required separate API requests
By batching API requests instead of making separate calls per tile, Bank of America halved their iPhone app response time to 0.75 seconds.
About This Article
Bank of America found that over 80% of mobile usage happens inside apps rather than browsers. This meant mobile app performance directly affected how customers engaged with the bank.
Vinay Sodha's team set up Adobe Target's REST API version 2 to handle personalization on the server side. This let them extend personalization to mobile apps through HTTPS calls, not just web browsers.
Android response times stayed around 1.5 seconds. The bank then created a plan to optimize more customer touchpoints beyond the initial four home screen tiles.
