Workflow
Structured Delivery From Concept to Launch
A phased approach ensured seamless collaboration, predictable outcomes, and rapid iteration.
Phase 1
Discovery and technical analysis
Zoolatech worked with Credible’s engineering team to analyze existing partner integrations, identify iframe limitations, and define SDK goals.
Phase 2
Architecture design
Engineers designed a modular JavaScript SDK structure supporting multiple widgets, secure cross-domain messaging, and future scalability.
Phase 3
Development and iteration
The team built and refined the SDK using the PostMessage API, adding partner-defined callbacks, analytics hooks, and configuration flexibility.
