An FD SDK connects customer journeys, payments, issuer systems, and servicing operations. A useful service-level agreement must explain more than an uptime percentage. It should define how incidents are classified, communicated, investigated, and resolved across dependencies.
Start by identifying which components the provider operates and which depend on issuers, payment systems, identity services, the host platform, or telecommunications networks. Availability calculations are difficult to interpret without a clear boundary.
Ask whether the SLA covers:
Severity definitions should be based on customer and business impact. A complete outage, widespread booking failure, isolated issuer issue, degraded dashboard, and documentation defect should not share the same response process.
For every severity level, define acknowledgment, investigation, update cadence, workaround expectations, escalation, and resolution or recovery targets.
Ask how the provider thinks about service restoration, data recovery, transaction reconciliation, and customer communication. Financial workflows require special attention when a system recovers but some payments or applications remain in an uncertain state.
Recovery should include a plan to identify affected records, establish authoritative outcomes, prevent duplicates, and communicate the next safe action.
An FD platform depends on external systems. Exclusions may be reasonable, but they should not eliminate operational responsibility. The provider should still monitor dependencies, surface the affected issuer or workflow, maintain escalation paths, and support reconciliation.
Review maintenance windows, notice periods, emergency changes, version support, backward compatibility, sandbox availability, and deprecation policy. Issuer-driven changes should be tested and communicated with enough time for partner validation where possible.
Confirm support hours, severity channels, named escalation paths, information required in a ticket, and how business and technical teams coordinate. A support commitment is more useful when it identifies ownership instead of offering only a shared inbox.
Monthly or quarterly reporting should distinguish availability, latency, error rates, callback delivery, issuer-specific incidents, reconciliation exceptions, support performance, and planned maintenance. Review trends, not only aggregate averages.
