RichSol integrates third-party APIs and builds custom ones, securely and at scale. And here is our edge: we also own SMS, voice and WhatsApp APIs, so we can plug messaging straight into your systems — something most integration shops cannot offer.

Client Success Story
Case Study
An online seller manually re-entered every order into their accounting and courier tools, causing delays and mistakes. We integrated their store with the payment gateway, a shipping API and Tally, so each order flowed end-to-end automatically. We then connected our WhatsApp API to send instant order and tracking updates — the kind of cross-system automation that comes from a partner who owns both integration and messaging.
“Orders now flow from checkout to courier to accounts automatically — and customers get WhatsApp updates instantly. No more manual entry.”
— Operations Head, Indian online seller
