Veeva Vault Reference Architecture

Overview

Guidance for reference architecture with Veeva Vault REST API, VQL queries, and VAPIL Java SDK.

Instructions

Key Vault API Concepts

Authentication: Session-based (username/password or OAuth 2.0)
Base URL: https://{vault}.veevavault.com/api/v24.1/
VQL: SQL-like query language for Vault data
VAPIL: Open-source Java SDK covering all Platform APIs
Lifecycle: Documents flow through states (Draft > In Review > Approved)

Common VQL Patterns

-- List documents by type
SELECT id, name__v FROM documents WHERE type__v = 'Trial Document'

-- Find objects
SELECT id, name__v FROM site__v WHERE status__v = 'active__v'

-- Join related objects
SELECT id, name__v, study__vr.name__v FROM study_country__v

Error Handling

Error	Cause	Solution
`INVALID_SESSION_ID`	Session expired	Re-authenticate
`INSUFFICIENT_ACCESS`	Missing permissions	Check security profile
`INVALID_DATA`	Bad VQL or field name	Validate against metadata
`OPERATION_NOT_ALLOWED`	Lifecycle state conflict	Check document state
