Fintech, MTO, or marketplace wanting to sell airtime, mobile data, utility vouchers or CanalPlus across West Africa? You'd normally negotiate with each operator and integrate five APIs. Pillar replaces that with one endpoint. We continue signing the contracts and wired the routing. - POST /v1/transactions → we pick the operator, return a signed webhook when it lands. - Idempotent retries, multi-currency wallets, KYB built in. - 9 countries, 17 operators, sandbox + production.
