Prove unlocks faster time-to-value with Speakeasy-powered SDKs

“Speakeasy has been a really good partner for us. We’ve been able to get support quickly when needed, and the platform has significantly streamlined our SDK generation process. It’s allowed our internal teams to integrate with our services much faster, and our customers benefit from a smoother, more efficient onboarding experience.”

Joseph Spurrier, Senior Staff Engineer at Prove

Prove (opens in a new tab), a leading provider of identity verification solutions, relies on APIs to deliver its services to customers, including Prove Pre-Fill®, Prove Identity℠, and Prove Verified Users℠.

Prove adopted Speakeasy to automate the generation and maintenance of high-quality, server-side SDKs. This has resulted in significantly reduced integration times, improved developer experience, and faster time-to-market for Prove and its customers.

Challenge: API Docs Alone Leads to Slower, Error-Prone Integrations

Prove’s customers and their own development team were spending too much time hand-building API integrations from API docs:

• Internal inefficiencies: Engineers had to write boilerplate code for service-to-service integrations. This led to wasted time and created opportunities for inconsistencies between implementations.
• Customer onboarding delays: Without SDKs, customers were left to build everything from scratch: handling OAuth token management, request/response formats, retries, and parsing API docs. With 10–12 endpoints per solution, implementation timelines stretched into weeks.

Solution: Automated SDKs Reduces Manual Work, Accelerates Integrations

Prove chose Speakeasy to automate the generation of server-side SDKs for both internal and external use. Speakeasy allows Prove to:

• Generate SDKs from OpenAPI specifications: This ensures consistency between the API documentation and the SDKs, eliminating API drift.

• Support multiple languages: Prove offers customer-facing SDKs in Go, TypeScript/JavaScript, and Java.

• Automate CI/CD: Speakeasy integrates seamlessly with Prove’s GitHub workflow, automatically regenerating SDKs whenever the API specification changes—eliminating the need to write custom CI/CD code.

• Customize SDK behavior: Speakeasy’s overlay feature allows Prove to fine-tune SDK behavior without modifying the source specifications.

• Simplify Authentication: Speakeasy supports a custom authentication method for Prove.

• Streamline distribution: Speakeasy’s built-in support for publishing to npm, Maven, and other package repositories makes it easy for Prove to distribute SDKs to developers.

• Focus on core business logic: Using SDKs to integrate with APIs enables Prove’s developers to focus on building core product features rather than managing low-level integration details.

Results: Faster Integrations and Enhanced Developer Experience

Since adopting Speakeasy, Prove has experienced significant improvements in both internal development and customer onboarding:

• Reduced Internal Integration Time: Internal teams can now integrate with Prove’s services in a matter of hours instead of days.

• Faster customer onboarding: Thanks to simplified APIs and the availability of SDKs, Prove has cut customer implementation time in half, from initial conversation to production deployment.

• Improved Developer Experience: Both internal and external developers benefit from well-documented, easy-to-use SDKs, reducing frustration and accelerating development cycles. The SDKs handle OAuth token management and simplify request/response handling, allowing developers to focus on their application logic.

• Enhanced API Consistency: Speakeasy ensures that SDKs are always in sync with the latest API specifications, eliminating API drift and reducing integration errors.
