API diagnosis, Webview business case and multi-method integration strategy
background
Historical BNPL leader in France, Oney is being challenged on two essential dimensions:
- The speed and quality of integration of its solution (3 weeks vs 48 hours for competitors),
- the ability to address new segments (x10, BNPL pro, etc.).
To maintain a competitive advantage, Oney has given Theodo two successive missions:
- Technical diagnosis and API recommendations
- Business & technical evaluation of a webview integration method

Our approach
What made the difference
Consolidated vision via structuring benchmarks
Sequence diagrams, C4, lead time analysis, and detailed BNPL model comparisons.
Voice of the customer approach
Onboarding a client ambassador to validate the recommendations.
Product + tech + business analysis
Study of widget, API, SDK and Webview solutions to define an objective decision-making framework.
Our impact
A complete diagnosis of the existing API
A BNPL B2B shortlist
A complete business case
Oney now has a clear vision to accelerate its merchant integrations and strengthen its competitiveness in the face of new entrants.
