Test / Usage

curl -d '{"body":"new contrib from toto: [44](http://radio.localhost/map/#44)", "key": "secret"}' \
  'http://matrixwebhook.localhost/!DPrUlnwOhBEfYwsDLh:matrix.org'

Formatters

These formatters will output custom messages depending on the specific formatter. Generally to set these up, on the remote provider you would create a webhook with https://your.webhook.domain/?formatter=<formatter columun below>&api_key=<your apikey>

formatter	description	key location
github	for github.com	in github JSON webhook settings as secret
grafana	for grafana	in webhook URL with api_key=<yourkey>
pingdom	for pingdom.com	in webhook URL with api_key=<yourkey>
buildbot	buildbot reporter	in webhook URL with api_key=<yourkey> or in master.cfg credentials header as api_key
generic	returns raw JSON that was recieved. For developing additional formatter plugins	in URL with api_key=

For example, if your matrix-webhook was hosted at https://webhooks.example.com, and you were setting up pingdom and you have an api_key of "123", you would use the following URL for your webhook call from pingdom: https://webhooks.example.com/?formatter=pingdom&api_key=123
