Build a Guidewire ClaimCenter FNOL API integration with automatic reserve setting and coverage validation

Steps

1. Authenticate to the Guidewire ClaimCenter Cloud API using OAuth 2.0 client credentials or the authentication method configured for your environment
2. Submit a new FNOL by calling the ClaimCenter REST API claim creation endpoint with structured loss data including policy number, date of loss, loss cause, and claimant details
3. Trigger coverage verification by querying the policy data associated with the claim to confirm active coverages and deductibles at the date of loss
4. Create exposures on the claim corresponding to each coverage line applicable to the reported loss
5. Set initial reserves for each exposure by posting reserve amounts to the ClaimCenter reserves endpoint, following the carrier's reserving guidelines for the loss type
6. Retrieve the created claim number and exposure identifiers to store in the originating system and provide to the claimant as a reference
