Understand the difference
Lithic vs i2c
i2C's transaction decisioning and broader program configurations exist in a black box clients can't access. Lithic gives you transparent authorization, configurable fraud protection, and APIs built for speed and control.

Compare key capabilities
The capabilities that inform your reliability, control, and reconciliation speed.
Developer Experience
API-first platform with OpenAPI spec and a self-serve sandbox. Ship in weeks.
Weak API documentation, integration guides, and bare-bones sandbox environment.
Authorization Intelligence
Rules set at the card, or cardholder, or program level with real-time webhooks and granular reason codes.
Rules are primarily program-level. Limited visibility into individual decline reasons.
Reconciliation
One transaction identifier ties auth, clearing, and reversal together. Clean data out of the box.
Fragmented transaction data requires manual work to reconcile and report.
Program Support
Dedicated payments experts with direct access and fast turnaround.
Overseas support agents lack the context and direct communication channels to quickly resolve issues.
Why clients choose Lithic over
i2C
Three places where the difference between Lithic and i2c shows up directly in data fidelity, developer experience, and support for your program.
01
If you want transaction clarity you can trust
i2C's unclear authorization decisions create support headaches, while program-level-only fraud rules force you to choose between security and a frictionless cardholder experience. Lithic delivers detailed decline codes and configurable fraud controls at every level, so you protect your program without sacrificing user experience.

02
If your developers want a first-class experience
i2C's outdated portals and thousand-page PDFs slow your team down. Lithic's modern developer-friendly APIs are easily tested in our sandbox, so your team can focus on building differentiated products, not troubleshooting set-up.

03
If seamless program support is a top priority
i2C’s outsourced support teams lack US payments experience, which means resolving issues takes weeks and your roadmap is stalled while you wait for answers. Lithic assigns dedicated experts to your account who quickly resolve issues.
