Who We Are
A narrow focus, kept deliberately narrow
Cloud API Link reviews one thing: the third-party API integrations sitting inside payment and banking-adjacent applications. We don't do general security audits or code reviews. That narrowness is intentional.
How this practice came together
Built from patterns seen across many integrations
The idea for a dedicated integration audit came from a recurring observation: teams building payment and banking-adjacent products are usually careful about their own code, but treat third-party APIs as a fixed, trusted layer once the initial integration is signed off. Vendor terms change. Rate limits get quietly adjusted. Sandbox credentials expire without much warning. None of this shows up in a normal sprint review.
Rather than folding this work into a broader security audit, where it tends to get a few bullet points and little depth, we built a review process that treats API dependency risk as its own discipline, with its own checklist, its own severity language, and its own reporting format.
What guides how we review
Four working principles that shape every engagement, regardless of the size of the integration surface.
Evidence Over Assumption
We verify against live configuration and current vendor documentation rather than relying on what a team believes is set up.
Plain Severity Language
Findings are categorized so that both engineers and non-technical stakeholders can understand what needs attention and why.
Confidential By Default
Access to systems and documentation is scoped narrowly and handled under a signed confidentiality agreement for every engagement.
No Disruption to Delivery
Audits are scheduled around your release calendar. We observe and document; we do not require code freezes or deployment pauses.
Who conducts the review
Reviews are led by people who have worked inside payment infrastructure
Engagements are led by reviewers with a background in backend systems for payment processing and banking-adjacent platforms, including time spent maintaining production integrations rather than only auditing them from the outside. That distinction matters. Knowing what it feels like to be paged at 2am because a vendor rotated a signing key without much notice changes what you look for in a review.
Every audit also includes a second-pass review by a separate team member before the findings report is finalized, so no single perspective goes unchecked.
How we work day to day
Most of our work happens asynchronously: reviewing API logs, vendor documentation, and configuration exports rather than sitting in on your team's daily standups. When we do need live access or a working session, we schedule it around your team's availability, not the other way around. Reports are delivered as structured documents, with a short walkthrough call offered at no extra step in the process.
