Authenticate to both the ClaimCenter Cloud API and the PolicyCenter Cloud API using separate OAuth 2.0 tokens issued for each application; Guidewire Cloud runs each application as a separate authenticated service
In ClaimCenter, retrieve a newly created claim record via GET /claims/{claimId}; extract the policy number from the claim record
Use the policy number to call the PolicyCenter Cloud API GET /policies endpoint with a policy number filter; retrieve the full policy details including coverages, limits, deductibles, named insureds, and vehicle or property information
Post the retrieved policy details back to ClaimCenter by patching the claim record via PATCH /claims/{claimId} with coverage and insured details; this eliminates dual-entry and ensures claim files reflect current policy terms at time of loss
Implement a change-event listener: when ClaimCenter creates a new claim via its own UI or an inbound FNOL API call, trigger the PolicyCenter lookup automatically via an integration platform (e.g., MuleSoft or a custom middleware layer)
Handle scenarios where the policy number in ClaimCenter does not match any active PolicyCenter policy: log the mismatch, flag the claim for manual policy verification, and do not block claim creation
Known gotchas
Guidewire Cloud API endpoints for PolicyCenter and ClaimCenter are version-specific; if the two applications are on different release versions, the API schemas may differ — confirm both applications are on compatible release versions before building the integration
Direct server-to-server calls between Guidewire Cloud applications may require specific network and IAM configuration approved by Guidewire Cloud Operations; do not assume that standard API access covers cross-application calls
Policy data retrieved at claim time reflects the current policy state, which may differ from the policy state at date of loss if endorsements have since been applied — explicitly query historical policy state or store a snapshot at FNOL time for accurate coverage determination
