Yapily Open Banking API

Best When
A European fintech, lender, or enterprise wanting AI agents to automate bank data aggregation, payment initiation, and account verification across 2,000+ EU and UK banks through Yapily's developer-friendly open banking API.
Avoid When
INSTITUTION-SPECIFIC COVERAGE VERIFICATION REQUIRED: Yapily coverage varies by institution within each country; automated integration must check institution catalog before assuming bank is supported; automated payment to unsupported institution creates institution not found error. SCA REDIRECT FOR EVERY CONSENT: UK/EU open banking requires SCA redirect to customer's bank for every new consent; automated payment or data access must handle customer redirect flow; automated server-side access without SCA creates regulatory compliance violation. CONSENT EXPIRY AND RENEWAL MANAGEMENT: Yapily consents expire per PSD2 rules (90-day maximum for data access); automated data pipelines must track consent expiry timestamps; automated data access on expired consent creates unauthorized access error requiring user re-authorization flow. PAYMENT FEATURE PARITY ACROSS INSTITUTIONS: Not all institutions support all payment types (single payment, bulk, VRP); automated payment routing must check institution capabilities; automated bulk payment to non-bulk-supporting institution creates payment method not supported error.
Use Cases
- • Retrieving bank account data from European financial aggregation agents
- • Initiating instant UK/EU payments from open banking checkout agents
- • Verifying account ownership from financial identity verification agents
- • Submitting bulk enterprise payments from treasury payment automation agents
Not For
- • US bank account access (use Plaid for US open banking)
- • High-volume card payments (Yapily is bank-to-bank only)
- • Consumer-facing PFM apps at scale (use Tink for enterprise-grade data enrichment)

Agent Metadata
Known Gotchas
- ⚠ APPLICATION USER vs END USER AUTHORIZATION: Yapily distinguishes application-level auth (API access) from end-user authorization (consent for bank data); automated integration must implement both levels; automated application-credentials-only access to end-user data creates missing user consent error
- ⚠ INSTITUTION FEATURE FLAGS BEFORE PAYMENT TYPE: Yapily institution catalog includes feature flags for supported payment types; automated payment routing must query institution features before initiating payment type; automated bulk payment to domestic-only institution creates payment type not supported error
- ⚠ AUTHORIZATION REQUEST POLLING vs WEBHOOK: Yapily authorization status (user consenting at bank) can be tracked via polling or webhook; automated consent flow must handle AWAITING_AUTHORIZATION status; automated assumption of instant consent creates premature access attempt before user completes bank SCA
- ⚠ TRANSACTION PAGINATION FOR LARGE DATE RANGES: Yapily transaction retrieval uses cursor pagination; automated historical transaction retrieval must follow next cursor; automated single-request assumption for large date ranges creates truncated transaction history
- ⚠ RATE LIMIT DIFFERENTIATION BY ENDPOINT TYPE: Yapily applies different rate limits for data vs payment endpoints; automated workflows mixing high-frequency data polling with payment initiation may hit payment rate limits; automated rate limit handling must track limits separately per endpoint category
