What can you build with Guidewire ClaimCenter REST API?

Guidewire ClaimCenter REST API is a Company API. Developers commonly use company APIs for:

enriching CRM records with company firmographics
building lead-generation and prospecting tools
verifying business identity and registration details
monitoring competitors and market intelligence
powering B2B data enrichment pipelines

OAuth 2.0. OAuth lets your app act on behalf of a user. You redirect them to authorise access, receive a token, then use that token in requests. Best for accessing user-owned data. Guidewire ClaimCenter REST API is a paid API — check the provider's pricing page before building a production integration.
