⚡ Reliability
Best When
A South African fintech, lender, insurer, or e-commerce merchant wanting AI agents to automate instant bank payments, debit order mandates, and bank account data access through Stitch's South Africa open banking platform.
Avoid When
CONSUMER BANK REDIRECT FOR BANK AUTHENTICATION: Stitch Pay by Bank redirects consumer to their internet banking for authentication; automated checkout must redirect consumer to bank authentication URL; automated server-side payment without bank redirect creates no authorization mechanism. DEBIT ORDER REQUIRES NAEDO/AUTHENTICATED MANDATE: Stitch debit order collection requires authenticated mandate from consumer; automated recurring debit must complete mandate collection flow; automated debit without mandate creates unauthorized_debit and NAEDO rejection. BANK COVERAGE VARIES: Stitch covers major SA banks (FNB, Standard Bank, Absa, Nedbank, Capitec) but smaller banks may be limited; automated payment should check bank availability; automated universal SA bank assumption creates bank_not_supported for smaller institutions. FINANCIAL DATA ACCESS REQUIRES USER CONSENT: Stitch account data access (transactions, balance) requires user OAuth consent per account; automated data access pipeline must complete consent flow; automated server-side data pull without consent creates unauthorized_data_access.
Use Cases
- • Accepting instant bank payments for South Africa e-commerce checkout agents

Not For

Agent Metadata
Known Gotchas
- ⚠ GRAPHQL NOT REST: Stitch API is GraphQL not REST; automated integration must use GraphQL queries and mutations; automated REST-style endpoint calls create 404 or wrong endpoint errors; use Stitch's GraphQL client libraries
- ⚠ BANK REDIRECT FOR PAYMENT AUTHENTICATION: Stitch Pay by Bank returns redirectUri requiring consumer authentication at their bank; automated checkout must redirect consumer to redirectUri; automated server-side payment without redirect creates no payment authorization
- ⚠ DEBIT ORDER MANDATE FLOW IS MULTI-STEP: Stitch debit order requires mandate collection (user authorizes), then activation, then collection; automated recurring payment must complete mandate flow in sequence; automated debit without prior active mandate creates unauthorized_debit
- ⚠ FINANCIAL DATA SCOPE IS USER-SPECIFIC: Stitch financial data access (transactions, balance) is scoped to user who authenticated via OAuth; automated data pipeline must obtain consent per user; automated business-level financial data pull without user OAuth creates scope_insufficient
- ⚠ WEBHOOK EVENTS REQUIRE VERIFICATION: Stitch webhooks are signed; automated webhook processor must verify signature; automated unverified webhook creates spoofed payment event vulnerability
