Bill payments are higher-stakes than airtime top-ups: a customer expecting an electricity token or a cable TV renewal notices immediately if something goes wrong. The best bill-payment API handles this for you - verify before charging, idempotent retries, and auto-refunds when a delivery fails. Plustive is our pick for developers who want those guarantees by default.
What to look for in a bill-payment API
- Verify-then-pay - electricity and cable TV should confirm the meter/smartcard number is valid before any money moves, and return the customer name for confirmation.
- Token in the response - the prepaid electricity token or cable renewal confirmation should be in the purchase response, not in a second lookup.
- Idempotency - a reference that makes retries safe; customers waiting on a token will retry, and the API must not charge twice.
- Auto-reconcile + refunds - failed deliveries should refund your wallet automatically, not require a support ticket.
- Education PINs handled correctly - no verify step exists for WAEC/NECO/JAMB; the PIN is issued on purchase, so idempotency is especially critical here.
