Custom API and back-end development on HubSpot
Tired of lags, silos or data not landing where it should? We understand.
Some connectivity isn't provided natively on HubSpot, but that doesn't have to be the case.
Our developers create tailor-made APIs to synchronize your tools, streamline your processes and ensure you have the right information, in the right place, at the right time.
Say goodbye to headaches and hello to perfect digital harmony.

HelloWork
Website redesign
HelloWork entrusted us with the redesign of their recruiter site, with the aim of creating a modern design and making content management totally autonomous. In less than a month, we developed a custom template via HubSpot, enabling their team to build and adapt their pages easily, without the intervention of developers.
Hellio
Development of a dynamic RGE directory
Hellio, a player in the energy transition, wanted to promote RGE-certified craftsmen and facilitate their connection with customers. If/else agency developed a dynamic directory connected via API to the ADEME database and integrated with HubSpot, enabling multi-criteria searches (type of service, postal code, field). The result: an automated, reliable, and easy-to-use tool that has enhanced the user experience and customer satisfaction.
