# Regional payment integrations for international commerce

We implemented and maintained payment integrations across international commerce environments, supporting regional methods and merchant configurations. Our work combined checkout engineering, payment failure diagnosis, release verification, and diagnostic instrumentation, connecting provider-specific requirements with the operational steps needed to deliver and maintain changes across regions.

## The challenge

An international commerce brand needed payment methods and merchant configurations
to work across regional storefronts. Integration changes had to fit the checkout
flow and fraud controls, then move through commerce environments with verification
and rollback planning. Ongoing checkout issues also required practical diagnosis.

## Our contribution

5PM implemented and maintained payment integrations on Salesforce Commerce Cloud.
The engagement covered Adyen, CyberSource, Apple Pay, Amazon Pay, PayPal, WeChat Pay,
and 3D Secure, alongside regional merchant configuration and fraud controls.

We combined hands-on checkout development and failure diagnosis with release
coordination, configuration promotion, and diagnostic instrumentation.

## Integration approach

We examined payment behavior across the checkout flow, from collecting payment
information to authorization. Provider requirements, merchant configuration, and
application behavior all informed implementation and investigation of differences
between environments.

Release work covered Git and CI/CD, Business Manager configuration promotion,
cutover verification, and rollback planning. This connected changes to payment code
with the configuration and delivery steps needed across commerce environments.

Splunk and Google Tag Manager event instrumentation improved diagnostic visibility
into checkout and integration failures, supporting investigation across the
storefront and its external dependencies.

## What the work enabled

The work supported regional payment methods and merchant configurations, coordinated
releases of code and configuration, and clearer verification and rollback steps.
Diagnostic instrumentation gave the teams investigating checkout failures more
visibility into payment and integration behavior.
