Please add support for V2 of webhooks and API for Pipedrive. V1 is slated to be deprecated. V2's implementation of custom fields is different and will require rebuilding many of our automations.
In addition, V2 API supports updating Labels, which a few people have already identified as a need with this application.
Adding V2 support sooner than later will help avoid having to rebuild many of the automations I'm about to build.
