OLB / Developers
Build on OLB.
Payments, commerce, and merchant-onboarding APIs on the SecurePay gateway — the same infrastructure underneath every OLB product, with agentic interfaces next. Public API reference documentation is being prepared; talk to OLB for early access.
Why build here
One gateway.
Every surface.
SecurePay is PCI-compliant and certified by Visa and Mastercard, with 3D Secure authentication, PayPal and QuickBooks integration, and AI-based risk assessment. What OLB’s own products run on is what you integrate with.
The API surface
01
Payments API
Card and ACH processing, tokenization and a customer vault, recurring and custom billing models, refunds, and settlement.
02
Commerce API
Storefronts, catalogs, and orders across OmniSoft and iStores.com AI — online checkout through in-person tap to pay.
03
Onboarding & risk
Same-day merchant approval workflows with automated risk assessment, plus webhooks for transaction and account events.
