Guidewire Hello World

Overview

Execute your first Cloud API calls to PolicyCenter, ClaimCenter, and BillingCenter. All Guidewire Cloud APIs are RESTful with JSON payloads and follow Swagger 2.0.

Instructions

Step 1: Query PolicyCenter Accounts

typescript
const token = await getGuidewireToken();
const headers = { 'Authorization': `Bearer ${token}`, 'Content-Type': 'application/json' };

// List accounts
const accounts = await fetch(`${process.env.GW_PC_URL}/account/v1/accounts?pageSize=5`, { headers });
const data = await accounts.json();
data.data.forEach((acct: any) => {
  console.log(`Account: ${acct.attributes.accountNumber} | ${acct.attributes.accountHolderContact.displayName}`);
});

Step 2: Query ClaimCenter Claims

typescript
// List recent claims
const claims = await fetch(`${process.env.GW_CC_URL}/claim/v1/claims?pageSize=5`, { headers });
const claimData = await claims.json();
claimData.data.forEach((claim: any) => {
  console.log(`Claim: ${claim.attributes.claimNumber} | ${claim.attributes.status.code} | ${claim.attributes.lossDate}`);
});

Step 3: Guidewire API Response Structure

json
{
  "count": 42,
  "data": [
    {
      "attributes": { "accountNumber": "A000001", "...": "..." },
      "checksum": "abc123",
      "links": { "self": { "href": "/account/v1/accounts/pc:123" } }
    }
  ],
  "links": { "next": { "href": "/account/v1/accounts?pageSize=5&offsetToken=..." } }
}

Key patterns: data[] array, attributes for fields, checksum for optimistic locking, links for pagination.

Error Handling

Error Code Solution
404 Not Found Invalid endpoint path Verify /account/v1/accounts format
400 Bad Request Invalid query params Check pageSize, filter syntax
422 Unprocessable Business rule violation Read userMessage in response
409 Conflict Stale checksum Re-GET resource, use new checksum
