llms.txt Changed How I Integrate APIs: A Reton Case Study With Interswitch VAS
I build Reton , a trust-first digital wallet for Africa. Our flagship is Callback Protection: hold a payment, release it when you are ready, or raise a callback, with a timeline a person can actually follow. A wallet that only moves money between Reton IDs is incomplete. People still buy airtime, data, electricity, and television. If they have to leave Reton to pay those bills, the balance stops…
Reton is a digital wallet for Africa which offers Callback Protection, allowing users to hold payments, release them at their own convenience, or request a callback with a specific timeline. The company wanted to integrate Value Added Services (VAS) from Interswitch but needed a clean text version of the VAS documentation rather than a rendered marketing site.
The solution was to create llms.txt, a machine-readable map of the Interswitch documentation site, which enabled Reton to fetch the necessary VAS documentation as Markdown pages, avoiding the need for human intervention in the integration process. By treating Interswitch as a payments partner and not a bank, and sticking to a strict call chain for bill payments, Reton was able to integrate VAS into its digital wallet without compromising the integrity of its own double-entry ledger system.
