The Problem: Invalid Vendor Bank Details
Multi-vendor marketplaces and platform businesses face constant friction when onboarding international sellers. Vendors frequently mistype their bank routing numbers or IBANs during registration. When payout day arrives, payments bounce back, resulting in delayed vendor payouts, support overhead, and frustration.
What to Validate During Onboarding
- Real-Time Input Check: Prevent sellers from submitting improperly formatted IBANs in your signup or vendor settings form.
- Country & Length Verification: Ensure correct character counts for SEPA and global bank accounts.
- Institutional Routing Lookup: Automatically fetch bank names and BICs (fully supported for Germany via Bundesbank data) to confirm bank existence.
How the PayeeValidate API Helps
Embedding our lightning-fast API into your frontend vendor onboarding form gives sellers instant feedback if their IBAN contains a typo or fails MOD-97 checksum validation, ensuring clean payout data from the start.
Honest Scope & Limitations
Validation confirms formatting, checksums, and bank registry mapping. It does not verify real-time account ownership or balances due to banking privacy regulations.
