Transaction validation
The problem
When validation happens after a transaction is written to the ledger, the damage is already done. Invalid writes create compliance violations, trigger costly rollbacks, and erode data integrity. Remediation is expensive, time-consuming, and often incomplete.How Flowker solves it
Flowker orchestrates all validation checks — KYC, AML, fraud scoring, balance verification — before anything reaches the ledger. You define a workflow that sequences these checks in the order your compliance policies require. Only transactions that pass every step are allowed to proceed. If any check fails, the workflow stops. No invalid data enters your system. Every decision point is logged automatically.Business outcome
- Zero invalid ledger writes — validation failures are caught before they become costly problems
- Complete audit trail — every check, every result, every decision is recorded and searchable
- Reduced remediation costs — no more rollbacks, manual corrections, or regulatory explanations for bad data
Customer onboarding (KYC/AML)
The problem
Customer onboarding in financial services involves identity verification, document checks, AML screening, and risk scoring — often spread across multiple systems, teams, and manual handoffs. The process takes days or weeks, with no single view of where a customer stands or what’s been completed.How Flowker solves it
Flowker lets you define the entire onboarding sequence as a single workflow: identity verification, then document check, then AML screening, then risk scoring. Each step calls the appropriate external provider automatically. Conditional logic routes customers to enhanced verification when risk scores exceed your thresholds. The workflow tracks every step, so you always know exactly where each customer is in the process.Business outcome
- Onboarding time reduced from days to hours — automated sequencing eliminates manual handoffs
- Standardized process — every customer goes through the same validated steps, regardless of which team handles them
- Audit-ready from day one — regulators can see exactly what checks were performed, when, and with what results
Payment orchestration
The problem
Payment routing involves multiple providers, each with different APIs, authentication methods, and response formats. Building and maintaining custom integrations for each provider consumes engineering resources and creates fragile, hard-to-change payment flows.How Flowker solves it
Flowker coordinates multi-step payment flows as a single workflow: fraud check, then balance verification, then payment gateway call, then confirmation. Each provider is configured once as an executor with its own authentication and field mappings. If a provider call fails, Flowker handles retries automatically with exponential backoff. Circuit breakers prevent cascading failures when a provider goes down.Business outcome
- Consistent payment processing — every payment follows the same validated path
- Automatic failure recovery — transient errors are retried without manual intervention
- Provider resilience — circuit breakers isolate failing providers so the rest of your operations continue
Fraud detection workflows
The problem
In many systems, fraud checks are bolted on after the transaction is already in progress — or worse, after it’s committed. By the time a fraudulent transaction is flagged, the financial and reputational damage may already be done.How Flowker solves it
Flowker runs fraud scoring as a step within the workflow, before the transaction proceeds. Conditional branching lets you define different paths based on risk level: low-risk transactions pass through, medium-risk transactions trigger additional verification, and high-risk transactions are blocked entirely. Because fraud checks are part of the workflow definition, they’re consistent, auditable, and impossible to bypass accidentally.Business outcome
- Real-time risk decisions — fraud scoring happens before the transaction commits, not after
- Risk-based routing — different risk levels trigger different responses automatically
- No gaps in coverage — fraud checks are built into the workflow, not patched on top
Provider integration acceleration
The problem
Integrating a new external provider — whether for KYC, payments, fraud detection, or any other service — typically takes 3 to 6 months of engineering work. Custom code, unique APIs, authentication handling, error management, and testing consume roughly 40% of engineering time. And when you need to swap providers, the cycle starts again.How Flowker solves it
Flowker separates provider configuration from workflow logic. You configure a provider once — base URL, authentication, field mappings, response handling — and then reference it in any workflow. No custom code per provider. When you need to change providers, you update the configuration without touching your workflows. You can test provider connectivity before going live, and field mapping validation ensures your data transformations work correctly with sample data before production use.Business outcome
- Integration time reduced from months to days — configure instead of coding
- Reusable across workflows — configure a provider once, use it everywhere
- Provider flexibility — swap providers by changing configuration, not rewriting code
- Engineering time recovered — teams focus on business logic instead of integration plumbing
