Custom HTTP Header Slash Plugin

This plugin allows Mattermost administrators to create custom slash commands (similar to what can already be done through the UI) but with a configurable list of custom HTTP headers added to the GET or POST calls

Installation

1. Go to the releases tab of this Github repository and download the latest release.
2. Upload this file in the Mattermost System Console > Plugins > Management page to install the plugin. To learn more about how to upload a plugin, see the documentation.
3. Modify your config.json file (PluginSettings section) to include a map of custom slash commands and their desired custom headers as shown below.

Custom Slash Command Definition

Follow the same set of configurable properties as used in the built-in custom slash commands. Note, commands must have an alphanumeric name.

See example below:

        "Plugins": {
            "slash-header-inject": {
                "slashcommands": {
                    "weather": {
                        "autocomplete": true,
                        "autocompletedesc": "Display the weather",
                        "commandurl": "http://myweatherservice.com",
                        "customhttpheaders": {

                            "x-headery": "Y-Value",
                        },

                    }
                }
            }
        }
