Currently it only supports two webhook formats (Uptime Robot and another one), both of which, as I understand, are multipart/form-data. Unfortunately, the tool I'm trying to integrate with it (open source uptime-kume) only configurable bodies for JSON payloads on their end. Another option for me would be to integrate over email, but for that I need an SMTP gateway which I don't want to setup. Webhooks FTW!
