Version and published date are read from each registry's own metadata endpoint on the date above, not from prose. ActiveCampaign's own SDK page lists four libraries and marks only two of them as "Created and maintained by ActiveCampaign"; the other two are explicitly credited to third parties and are recorded here as official:false with the provider's own attribution. packages: - language: php registry: packagist name: activecampaign/api-php url: https://packagist.org/packages/activecampaign/api-php repository: https://github.com/ActiveCampaign/activecampaign-api-php install: composer require activecampaign/api-php official: true version: v2.0.3 published: '2017-04-26' note: >- DECAY SIGNAL. The provider's SDK page still presents this as "Created and maintained by ActiveCampaign", but the last Packagist release is from 2017 and the GitHub repository was last pushed 2021-07-26. It predates most of the v3 surface it is supposed to wrap — the WhatsApp, Segments V2, Partners and SMS Broadcast APIs all postdate it. - language: javascript registry: npm name: activecampaign url: https://www.npmjs.com/package/activecampaign repository: https://github.com/ActiveCampaign/activecampaign-api-nodejs install: npm install activecampaign official: true version: 1.2.5 published: '2018-03-13' note: >- DECAY SIGNAL. Published by the `activecampaign` npm account with author help@activecampaign.com and maintainers including `activecampaign-eng`, so first-party attribution is solid. Last release 2018; GitHub repo last pushed 2020-02-27. Like the PHP client it predates most of the current v3 surface. - language: php registry: packagist name: activecampaign/module-integration url: https://packagist.org/packages/activecampaign/module-integration repository: https://github.com/ActiveCampaign/module-integration install: composer require activecampaign/module-integration official: true version: 2.1.29 published: '2026-08-04' note: >- Magento 2.3/2.4 extension rather than a general API client, but it is genuinely first-party and it is the only ActiveCampaign-published package on any registry that is actively released. Included because it is the honest counterweight to the two abandoned SDKs above: ActiveCampaign still ships PHP, just not an API client. - language: ruby registry: rubygems name: active_campaign url: https://rubygems.org/gems/active_campaign repository: https://github.com/mhenrixon/active_campaign install: gem install active_campaign official: false maintainer: Mikael Henriksson version: 0.1.16 published: '2019-05-14' note: >- Listed on ActiveCampaign's own SDK page as "Rails ... Created and maintained by Mikael Henriksson" — provider-recommended, third-party maintained. Last release 2019. - language: python registry: null name: active-campaign-python url: https://github.com/adulmec/active-campaign-python repository: https://github.com/adulmec/active-campaign-python install: null official: false maintainer: Apollo Data Solutions version: null published: null note: >- Listed on ActiveCampaign's own SDK page as the Python option, credited to Apollo Data Solutions. It is distributed from GitHub only — the repository publishes no PyPI package, so there is no registry metadata endpoint to read a version from. version/published are null because the check ran and found nothing, not because the check was skipped. Three same-named PyPI packages exist and are all DIFFERENT projects: `active-campaign-python` 0.9.2 (Dennis Durling, github.com/tahoe/…, 2018-03-20), `activecampaign` (Ben Lopatin) and `activecampaign-python` 1.0.10 (Miguel Ferrer, 2023-08-09). None is the adulmec library the provider links, and none is first-party, so none is recorded as this package's release. agent_tooling: - language: javascript registry: npm name: '@activecampaign/postmark-mcp' url: https://www.npmjs.com/package/@activecampaign/postmark-mcp official: true version: 2.1.1 published: '2026-07-13' product: Postmark note: >- Published by ActiveCampaign (npm publisher dandigangi_ac) but it is the MCP server for POSTMARK, ActiveCampaign's transactional-email product, not for the ActiveCampaign marketing/CRM API. It is catalogued in all/postmark/ and is listed here only so the ownership is unambiguous. The ActiveCampaign platform's own agent surface is a REMOTE MCP server with no installable package — see mcp/activecampaign-mcp.yml. - language: null registry: github name: ActiveCampaign/activecampaign-plugin url: https://github.com/ActiveCampaign/activecampaign-plugin official: true version: null published: null license: MIT note: >- First-party Claude plugin (six Agent Skills, five slash commands, two subagents) layered on the remote MCP server. Distributed from GitHub, not a package registry, and the repository publishes no tags — version/published are null because there is nothing dated to read. Repository last pushed 2026-08-07. summary: total: 5 official: 3 official_api_clients: 2 languages: [php, javascript, ruby, python] registries: [packagist, npm, rubygems] finding: >- Both first-party API clients are abandoned. The newest release of either is 2018-03-13 (npm `activecampaign` 1.2.5); the PHP client last shipped 2017-04-26. ActiveCampaign has since published five additional OpenAPI documents and a 50-tool MCP server, none of which any first-party SDK covers. A developer following the provider's own SDK page today installs a library seven or more years older than the API it is meant to call. docs: https://developers.activecampaign.com/page/sdks x-evidence: - {url: 'https://developers.activecampaign.com/page/sdks.md', http_status: 200, fetched: '2026-08-13'} - {url: 'https://registry.npmjs.org/activecampaign', http_status: 200, fetched: '2026-08-13'} - {url: 'https://repo.packagist.org/p2/activecampaign/api-php.json', http_status: 200, fetched: '2026-08-13'} - {url: 'https://repo.packagist.org/p2/activecampaign/module-integration.json', http_status: 200, fetched: '2026-08-13'} - {url: 'https://rubygems.org/api/v1/gems/active_campaign.json', http_status: 200, fetched: '2026-08-13'} - {url: 'https://pypi.org/pypi/active-campaign-python/json', http_status: 200, fetched: '2026-08-13', note: 'Resolves to a different project (tahoe/active-campaign-python 0.9.2), not the adulmec library the provider links.'}
