Its own index page is titled "Community Supported Client Libraries" and states plainly that "these client libraries have not been security tested by Marketo"; only two entries appear under its "Official Libraries" heading, and both target the SOAP API that Adobe deprecated on 2026-07-31. The only first-party libraries with live registry metadata are the Marketo Mobile Engagement SDKs (iOS / Android), which are mobile-engagement SDKs, not REST API clients. Every package below carries a structured `version` + `published` read from the registry, because the decay is the finding: the newest first-party REST-era artifact in this list is a 2015 Maven plugin. official_sdk_count: 4 packages: # ---------- FIRST-PARTY (Marketo / Adobe) ---------- - language: java registry: maven name: com.marketo:MarketoSDK url: https://search.maven.org/artifact/com.marketo/MarketoSDK install: implementation 'com.marketo:MarketoSDK:0.8.13' official: true version: 0.8.13 published: '2024-08-14' source_code: https://github.com/Marketo/android-sdk scope: Marketo Mobile Engagement (Android) — push, in-app messaging, mobile tracking.

Not a REST API client. note: >- trunk.cocoapods.org/api/v1/pods/Marketo returns {"error":"No pod found with the specified name."} — the SDK is distributed from GitHub releases only, so there is no registry version to reconcile against. version/published read from the GitHub release list. - language: java registry: maven name: com.marketo:marketo_plugin url: https://search.maven.org/artifact/com.marketo/marketo_plugin official: true version: 2.1.0 published: '2015-11-02' scope: Marketo-published Maven plugin.

There is no first-party REST client library in any registry. - >- The two first-party SDKs with live registry metadata (MarketoSDK 0.8.13, 2024-08-14; ios-sdk 0.8.6, 2024-04-23) are Mobile Engagement SDKs and do not wrap the REST API this profile describes. - >- Marketo's published client-library index still links repositories that were never released to a registry under the linked name (usermindinc/node-marketo), and four of its fourteen community entries target the retired SOAP API.
