The Developer Gateway
to Chekin’s Trust Platform

Chekin SDK is a plug-and-play layer that turns complex guest verification and compliance into a simple integration. Connect your PMS, CRM, or booking system to the Chekin Trust Platform and instantly enable:

  • Verified digital identities
  • Regulatory guest reporting
  • Secure e-invoicing
  • Data integrity and GDPR compliance

One API — Complete compliance coverage

Forget building country-by-country compliance logic or maintaining police API updates.

Chekin SDK keeps everything up to date — from biometric ID verification and liveness checks to multi-country reporting and digital invoicing — all accessible through a unified API.

From “check-in” to “trusted identity,” every step runs through the same infrastructure that powers the Chekin Trust Platform.

Scaling in hospitality shouldn’t mean reinventing compliance

Every market has its own laws, authorities, and formats. Chekin SDK lets you scale globally while staying focused on your product — we handle the compliance complexity for you.

  • Guest Reporting
  • Police and Statistics Reporting
  • Creation and Secure Storage of Mandatory Legal Documents
  • ID Verification
  • e-Invoicing
  • Data Conservation and Protection

The smart choice for your PMS:
Buy Chekin SDK, don’t build from scratch

Why building this yourself is incredibly complex

Each country — and often each region — enforces different compliance rules for guest registration, ID verification, and reporting to authorities. Building this in-house means creating and maintaining:

  • Custom form logic for each jurisdiction with different data requirements and validation rules
  • Region-specific integrations with each authority’s API — different formats, authentication, and acceptance logic
  • Constant maintenance as regulations and APIs change across multiple countries

With Chekin SDK, you skip all that complexity

One integration covers full legal compliance across 15+ countries — guest registration, ID verification, tax reporting, and statistics — all within your existing product. No hidden workflows. No regulatory headaches. Just compliance, built in.
