ActiveCampaign

ActiveCampaign v2 Legacy API

The surviving v2 surface from ActiveCampaign — 1 operation, GET /api/2/template/share, which creates a shareable campaign template link. ActiveCampaign still advertises v2.json in its own /.well-known/api-catalog alongside v3, with no published end-of-life date.
