Costs of Calendar API vs. Using the Nylas APIs

When building an calendar integration directly, there are a few costs to consider. Will your team have the bandwidth to:

  • Manage server fleets at scale

  • Onboard and train teams to specialize in protocols

  • Pursue and maintain security certifications like GDPR and SOC 2 certification

  • Hire additional headcount to support ongoing maintenance and bugs

With Nylas, none of these costs apply — we manage servers, specialization, security certifications, and provide world-class support SLAs.

With Nylas, Everything is Secure. Everything is Connected.

Security is our top priority — we sweat the small stuff so you don’t have to. Nylas is SOC 2 Certified, Privacy Shield certified, GDPR compliant, and HIPAA and FINRA ready. Data from every email you sync is encrypted and isolated with multi-level permission checks.
