Accept cash PIN payments at your captive portal via OTT Voucher

How it works

OTT Voucher is a prepaid digital payment voucher that converts cash into a PIN code. Users purchase a voucher at a retail store and enter the PIN at the Powerlynx captive portal to pay for Wi-Fi access. The flow is the same as 1Voucher, the difference is the merchant network and credentials.

OTT requires a dedicated merchant account and four API credentials: API Username, API Password, API Key, and Vendor ID — all provided by OTT after account setup. To connect, navigate to Config / Finance / Payment Gateways / OTT in Powerlynx and enter all four values. The country must be set to South Africa under Config / System / Localization.

A Testing environment is available — use “Testing” in the Environment field to validate the full integration before switching to Production.

What this integration provides

• Cash-to-PIN redemption at the captive portal — no card or bank account required.
• Testing environment for pre-launch validation.
• Per-location OTT account configuration — different accounts per hotspot location.
• Payments tracked under Finance / Payments in Powerlynx.
• South Africa only.

Credentials required

API Username, API Password, API Key, Vendor ID — all from your OTT merchant account. Environment: Testing or Production.

Who uses this

South African operators whose preferred retail voucher partner is OTT rather than 1Voucher — township ISPs and community hotspot networks where users already use OTT vouchers for other prepaid services.

Requirements

• OTT Voucher merchant account.
• All four credentials from OTT.
• Country set to South Africa under Config / System / Localization.
