[Currently there is no way to change the headers, Method and body of a HTTP POST… notification.](https://docs.graylog.org/en/3.3/pages/alerts.html) This requires the receiving system to do the translation. What is needed is an option like the custom E-Mail template. It should work pretty much like the E-Mail template The input fields should be URL: http|https://Server{:port}/path/key/val.......?junk=val HTTP Method: GET|POST|DELETE|... Custom Heaaders: Header: value X-CustomerToken: value Body: Same layout as Email Template ## Why? The receiving system does not accept the default post method body and there is no way to change it. Make it just like the Email Template... Then I can do something like this: ``` <EVENT> <TITLE>${event_definition_title}</TITLE> <Description>${event_definition_description}</Description> <EVENTTYPE>${event_definition_type}</EVENTTYPE> <Fields> ${foreach event.fields field} <FIELD>${field.key}</FIELD> <VALUE>${field.value}</VALUE> ${end} </Fields> ... ${foreach backlog message} <MESSAGE>${message}<MESSAGE> ${end} </MESSAGES> ${end} </EVENT> ``` ## Your Environment * Graylog Version: v3.3.8+e223f85, (3.38 OVA)

Support for HTML email alerts/notifications ## Expected Behavior Either co…nfigurable or on by default, would be helpful in formatting and general visibility of the alert. As an example, when I want to include the stream URL via ${if stream_url}${stream_url}${end}, the URL will be exceptionally long in some cases. It'd be ideal to be able to format with <a> tags I looked around for some stuff on this and couldnt find anything (requests, posts on community board, etc) ## Current Behavior HTML is not rendered because the email is sent with the following headers Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 7bit ## Possible Solution In https://github.com/Graylog2/graylog2-server/blob/master/graylog2-server/src/main/java/org/graylog2/alerts/FormattedEmailAlertSender.java line 171 you could use org.apache.commons.mail.HtmlEmail instead of SimpleEmail. Calling setHtmlMsg and then setTextMsg if users have configured HTML email and their clients dont support it (just an idea) Although I am wiling to bet that this may cause issues with JMTE due to format and syntax requirements? ## Steps to Reproduce (for bugs) 1. Configure an alert/notification 2. Use HTML in the template 3. Send test email 4. Observe that the email header is text/plain and HTML is not rendered ## Context ## Your Environment * Graylog Version: 2.4.0 * Operating System: CentOS 7.4
