PAV API Description
PAV (Postal Address Verification) is a CASS Certified™ API designed to standardize, correct, and validate addresses in the U.S. and Canada efficiently in a single step. By ensuring that addresses are deliverable prior to sending out mail or packages, businesses can save valuable time, money, and resources. PAV plays a crucial role in maintaining data quality for customers located in both the U.S. and Canada. When it comes to Canadian addresses, the API focuses on verifying the city, state, and ZIP Code, requiring that the province name be abbreviated for proper ZIP Code appending. CDYNE provides trial license keys for all its web services, allowing users to test the APIs at no cost. As an Application Programming Interface, Postal Address Verification (PAV) simplifies the integration process, enabling an organization's IT department to set up the Web Service on a webpage, application, or database with just a few lines of code. The system requires no software purchases or installations, eliminating the need for complex learning curves, and the service's data is refreshed automatically each month to ensure accuracy. This makes PAV an invaluable tool for businesses looking to streamline their mailing processes and enhance customer satisfaction.

Plauti builds native data-quality applications that run entirely within your CRM environment. No data is sent to external servers or third-party processing services, and there’s no parallel infrastructure to maintain. Your data stays where it belongs: under your control, behind your security perimeter, governed by your own access model.
For Salesforce, Plauti addresses the full lifecycle of data quality:
> Prevention at entry: Real-time duplicate detection alerts users as they type, blocking bad data before it’s created.
> Detection from external sources: Identify duplicates coming from integrations, imports, and APIs, so data quality doesn’t degrade over time.
> Batch remediation at scale: Run powerful batch jobs to find, review, and merge existing duplicates, with full audit trails for compliance and governance.
> Contact data verification: Validate email addresses and phone numbers before they’re saved to reduce bounces and failed outreach.
All processing runs natively on Salesforce infrastructure. Plauti respects your existing profiles, roles, and permission sets, so there’s no separate login, no data synchronization layer, and no new security surface to harden.
For Microsoft Dynamics 365, Plauti provides similar control over duplicates with real-time alerts, API-driven detection, batch processing, and cross-entity matching. It’s designed for CRM admins and data stewards who need direct, immediate control over data quality without waiting on developers, external consultants, or long IT ticket queues.
