Guidewire API

Overview

Guidewire is the core operating system for property and casualty insurance carriers worldwide. Its three flagship cloud products — PolicyCenter for underwriting and policy lifecycle management, BillingCenter for premium collection and payment plans, and ClaimCenter for first notice of loss through settlement — handle the full insurance transaction for tier-one and tier-two P&C carriers across personal lines, commercial lines, and specialty risks. When an insurtech platform needs to read a carrier's policy data, check claim status, or pull premium figures for a renewal tool, that data almost always lives inside a Guidewire instance.

Guidewire exposes REST APIs for all three products, but access requires both Guidewire's partner approval and the carrier's consent to expose their cloud instance. The partner program is designed for certified Guidewire system integrators building carrier implementation projects, not for independent insurtech vendors that need to connect to an existing carrier's Guidewire environment. For most teams — a commercial lines MGA building an underwriting data feed, an AI claims triage tool, or a renewal platform that needs to pull policy terms across multiple carrier partners — neither the partner agreement nor the carrier configuration is within reach on a normal development timeline.

Integuru generates a production-ready HTTP API for Guidewire instances using direct HTTP requests against the same endpoints the Guidewire web application uses internally. Policy data, billing records, claims, certificates, and endorsements are all accessible through Integuru's API. The Production plan includes 24/7 on-call maintenance so that carrier-side configuration changes or session updates are handled before they affect your calls.

The web application layer. Guidewire's Cloud API partner program and the Guidewire browser-based web application are separate surfaces. Integuru works at the web application layer, using the same authenticated HTTP requests the browser client sends when a claims adjuster or underwriter navigates PolicyCenter or ClaimCenter. This is not a workaround; it is the same mechanism every Guidewire user exercises when they open a policy record in a tab.

Why Teams Need This Integration

The partner-and-carrier dual dependency creates specific blockers for the teams most likely to build on Guidewire data.

P&C insurtech platforms connecting to multiple carriers. A commercial lines quoting or renewal platform that works with ten carrier partners needs to read policy data from each carrier's Guidewire instance. Getting a separate partner agreement with Guidewire and a separate configuration consent from each carrier is not practical. Integuru connects to each instance through the web application layer, using the authentication credentials your team already has.

AI claims triage and FNOL tools. First notice of loss systems, AI-powered claims review tools, and reserve analysis platforms need read and write access to ClaimCenter. list_claims and get_claim_detail give these tools structured access to current claim status, reserve figures, adjuster notes, and payment history without requiring a Guidewire partner relationship.

Premium finance and billing platforms. get_policy_premium pulls written premium, payment plan details, and billing account balance from BillingCenter — the data that premium finance companies, installment billing platforms, and accounts receivable tools need to reconcile payments against policy accounts. Manual export from BillingCenter does not scale to a portfolio of hundreds of accounts.

MGA and wholesale broker platforms. Managing general agents that write on carrier paper through a Guidewire-backed carrier need programmatic access to policy and endorsement records to power their own front-end systems, reporting dashboards, and binding workflows. list_policies, get_policy_detail, and list_endorsements cover this without requiring the MGA to be a certified Guidewire implementation partner.

Insurance Workflows This Integration Covers

The ten planned actions span the three Guidewire products that hold carrier-side insurance data:

• Policy management (PolicyCenter): list_policies and get_policy_detail surface the full underwriting record including coverage terms, limits, deductibles, and policy status. list_endorsements tracks mid-term changes with effective dates and premium impact.
• Billing and premium (BillingCenter): get_policy_premium retrieves written premium, payment plan configuration, and billing account balance for finance tools, reconciliation pipelines, and renewal pricing workflows.
• Claims (ClaimCenter): list_claims and get_claim_detail provide claims management platforms, loss run aggregators, and AI triage tools with structured claim data including reserve breakdown, adjuster assignment, and payment history.
• Certificates and policyholders: list_certificates and get_certificate support certificate automation tools with holder and additional insured data. list_clients and get_client_detail give CRM and account management platforms a structured view of the policyholder record.

Adjacent Integrations

Integuru already operates in the insurance vertical. The GTL integration provides production-ready HTTP API access to GTL's group life insurance enrollment portal — the live anchor integration for the Insurance vertical on Integuru, demonstrating that insurance platform authentication and session management work in production today. The Velocity integration covers AML enrichment for lending and financial workflows, a credential management pattern directly analogous to how Integuru handles Guidewire instance authentication. The Wefunder integration covers 6 live actions on a gated financial platform with complex authentication flows, the same technical pattern that Guidewire's session-based web application represents.
