This invention relates generally to systems, methods, and computer program products that allow developers to build applications supported by Platform as a Service (“PaaS”) utilizing integrated webhooks, allowing developers to hook discrete actions into PaaS systems contingent on defined occurrence of requisite triggering events. In some embodiments developers utilize webhooks to invoke a POST method HTTP call with a payload describing the discrete action in response to the requisite triggering event, wherein the actions may be selected from a list comprising: builds, releases, add-on changes, formation changes or scale events, application destruction, logging disconnect actions, logging connect actions, and pipelined builds.
