Pakistan integration notes

• Country/currency are bound to your merchant account; do not send on create; not returned in payin/payout responses or completion webhooks
• Signed POST fields are top-level JSON keys (e.g. merchantOrderNo, payer_mobile, payee_account, extJson)
• timestamp is in seconds (not milliseconds)
• Use 2048-bit RSA keys

Callback verification (Pakistan)
