generated: '2026-09-09' method: searched source: >- Public package registries (npm, PyPI, RubyGems, NuGet, Packagist, Maven Central) and the First Data / GBSEcom GitHub organizations. First-party status confirmed from registry maintainer records (npm maintainer justin.slingerland@firstdata.com on @firstdata/first-data-gateway; npm maintainer payeezy.api@firstdata.com on payeezy) and from the @firstdata / first-data / GBSEcom namespaces. note: >- First Data merged into Fiserv in 2019. The First Data Gateway (IPG) client libraries are published under the GBSEcom ("Global Business Solutions eCommerce") organization, which is First Data's own eCommerce engineering org — the packages carry the @firstdata / first-data / FirstData.Gateway names and their descriptions say "First Data's IPG API (version 21.5.0)". Every one of the six first-party gateway SDKs was last published on 2021-11-19, and no release has followed in the four years since; Fiserv has since directed First Data and Payeezy gateway merchants to Commerce Hub. The dated release floor is the strongest abandonment signal available for this surface. packages: - language: java registry: maven name: com.github.GBSEcom:first-data-gateway url: https://central.sonatype.com/artifact/com.github.GBSEcom/first-data-gateway install: 'implementation "com.github.GBSEcom:first-data-gateway:1.15.0"' source: https://github.com/GBSEcom/java official: true version: 1.15.0 published: '2021-11-18' note: 22 published versions.
