⚡ Reliability
Best When
A South African merchant wanting AI agents to automate instant EFT payment acceptance from banked customers who don't have or prefer not to use debit/credit cards through Ozow's bank-integrated instant EFT network.
Avoid When
CUSTOMER BANKING APP INTERACTION REQUIRED: Ozow EFT requires customer to authenticate in their bank's app or internet banking portal; automated EFT checkout must redirect customer to Ozow payment page for bank selection and authentication; automated server-side EFT without customer interaction creates incomplete payment flow. SOUTH AFRICA INTERNET BANKING SESSION TIMEOUT: Bank internet banking sessions expire quickly (typically 5-15 minutes); automated checkout must complete within customer bank session; automated long-duration checkout flow with Ozow EFT creates session expiry before payment completion. HMAC SIGNATURE FOR ALL REQUESTS: Ozow requires SHA512 HMAC hash signature for payment requests; automated request generation must compute correct hash with all parameters; automated request without valid HMAC creates signature validation failure. PAYMENT STATUS POLLING OR NOTIFY URL: Ozow uses notify_url callback for payment confirmation; automated order fulfillment must implement notify_url endpoint and validate Ozow-signed notification; automated checkout without notify_url creates no payment confirmation event.

Agent Metadata
Known Gotchas
- ⚠ SHA512 HASH PARAMETER ORDERING: Ozow payment hash must be computed from parameters in specific alphabetical order; automated hash generation must sort parameters correctly; automated hash with incorrect parameter order creates signature mismatch validation failure
- ⚠ NOTIFY URL vs SUCCESS URL TWO-URL FLOW: Ozow uses notify_url (server-side confirmation) and success_url (customer redirect); automated fulfillment must use notify_url for payment confirmation, not success_url redirect; automated fulfillment on success_url redirect creates fulfillment before server-side confirmation
- ⚠ BANK MAINTENANCE WINDOW AWARENESS: South African banks have scheduled maintenance windows (typically Sunday early morning); automated EFT payment during bank maintenance creates temporary payment unavailability for specific banks; automated EFT must handle bank_unavailable error gracefully
- ⚠ TRANSACTION REFERENCE UNIQUENESS: Ozow requires unique transaction reference per payment; automated retry must generate new transaction reference; automated same-reference retry creates duplicate transaction conflict
- ⚠ SETTLEMENT T+1 SOUTH AFRICAN BANKING: Ozow EFT settlement follows South African banking T+1 schedule; automated reconciliation must account for South African public holidays; automated daily reconciliation without SA banking calendar awareness creates reconciliation mismatch on public holidays
