Case overview

How we created a customized API and the unexpected value for Swikly

Client Overview

Swikly is a new platform providing caution management for all rental businesses (from a few hours to several months), providing :

- Simplification for the caution process for its B2B partners

- Automation and data safety via their platform

- End users benefit from a higher credit card cap

In order to improve their partner experience, Swikly is exposed to credit card default, and we have designed for them an insurance product to protect them against it.‍

The challenge

Our "classic" API was ill suited for the connection between Swikly and our platform :

  • Our data model was over-specified (we did not need payment splitting, full subscriber/insured/beneficiary model...)
  • It was getting tedious to try to map our datapoints to our partner's business reality
  • We could not provide good documentation and development tools fast enough

Our solution

Together with our partner Swikly we pioneered a new approach :

   We started with a blank page to design a new API  

  • no need to support unnecessary usecases  
  • every datapoint has a meaningful, business-driven signification (good code documents itself)

    We used a modern data description language (GraphQL) to     provide tooling

While implementing the new solution, we have supported with Swikly a double connection (legacy and new API) to avoid slowing the launch of the product.

We have since improved our solution to bring the same approach to every product launch, extending our compatibility to classic REST APIs and flat files to bring theses improvements to all of our partners.

Achieved Results

Delay divided by 3 : 1 week instead of 3

  • We didn't need to document custom APIs  
  • We removed the localization barriers (date formats, language...)  
  • Our partner was onboard with the process as soon as it's created

We embraced our partner's operational model : some have better access to data snapshots, other to data streams... we can integrate these differences in the created custom data model

Our custom APIs are no longer a one-way data link : they have become a sharing space where we can push     information back to our partners, in their desired format.

Unexpected     value for Swikly : Beyond specific use to implement insurance solution, this approach enabled     them to automate other business processes (non directly related to our     business with them) e.g. Accounting process automation.
