How TransferGo adopted AsyncAPI

TransferGo, founded in 2012, serves over 8 million customers in 160+ countries by providing fast and affordable international money transfers. In 2021, its Backend Guild faced challenges with inconsistent API documentation and schema maintenance across dozens of services and hundreds of channels. To solve this, TransferGo adopted a code-first AsyncAPI approach with internal PHP/.NET libraries, integrated validation and optimization pipelines, and automated publishing of schemas to a centralized Port.io Developer Portal.
