Setting up myPOS in PremiumPress

Activate the free plugin, then open your theme’s payment settings and add your myPOS credentials:

• Store ID (SID) — myPOS → Online payments → Store ID.
• Wallet number — Your myPOS wallet (client) number.
• Key index — The key index of the private key registered in your myPOS store (usually 1).
• Private key (PEM) — Your RSA private key in PEM form. Its public counterpart must be registered in your myPOS store; it signs the IPCPurchase request.

Amounts are sent with 2 decimals. One-time only — myPOS recurring card tokens are not wired here. Requires the OpenSSL PHP extension. The plugin requires PremiumPress 12.
