Garanti BBVA API Market

From API documentation to a self-service integration experience.

The Client

Garanti BBVA’s e-commerce API market brings the bank’s payment and commerce services together in a developer-facing environment, where technical teams can search for services and work through the documentation behind them.

The Challenge

Technical teams of very different maturity levels had to find the right API and its documentation, and implement it with minimal support dependency, inside an environment that also had to make adjacent services discoverable in context.

Our Approach

We treated the portal as a developer product rather than a marketing site: mapping integration intents, restructuring the information architecture around service discovery, and designing documentation as part of the journey instead of an appendix to it.

The Solution

A search-led API market experience: services grouped into meaningful API categories, documentation woven into the discovery path, and contextual routes to related capabilities — all expressed through the Garanti BBVA design system.
