Adeslas · Custom development and API integration
An internal tool for the sales network of an exclusive Adeslas agent, integrated with the SegurCaixa Adeslas APIs to price and sign up health insurance policies from a single place. A bespoke build on React and Node, with our own backend guarding the credentials and a dedicated server. In production since autumn 2026.
Connecting to an insurer's APIs is not just another form: several APIs, each with its own manual, OAuth2 authentication whose secret must never reach the browser, a test environment and a live one, and real policies behind every call. The goal was for the sales team to work from a single tool of their own, with proper tracking and without exposing a single credential.
We split the tool in two: a web application for the sales team and our own backend, the only piece that talks to Adeslas, which keeps the secret, manages the token and logs every operation. On that base we built the flows the team uses every day to quote, sign up and track their applications, with the agent's own rules applied before anything leaves for the insurer.
The tool has been in production since autumn 2026, and the sales team quotes, signs up and tracks its policies from it. It picks up where our Adeslas website and quote calculator for the same network left off: first attract and quote, now sign up. For us it is also proof that connecting your operation to a large supplier's API (an insurer, a bank, a logistics operator, an ERP) is well within reach when it is done with your own backend, proper testing in a safe environment and close follow-up from day one.
