Upload the contents of the `cloudbridge-mattermost` folder to the `/wp-content/ plugins/` directory 2. Activate the plugin through the ‘Plugins’ menu in WordPress 3. Configure the basic settings, such as the webhook URL 4. To enable OAuth2 authentication, you’ll need to configure your Mattermost instance to allow this: [OAuth 2.0 Applications](https://docs.mattermost.com/developer/oauth-2-0-applications.html) ## FAQ ### Is the plugin locale aware Cloudbridge Mattermost uses standard WordPress functionality to handle localization/ locale. The native language localization of the plugin is English. It has been translated to Swedish by the author. For notifications sent to Mattermost, there is a setting since 1.1.0 that will allow you to override all such messages to be in en_US locale (English). ### Are there any incompatibilities This is a hard question to answer. There are no known incompatibilities. ### Is there a way to customize the Mattermost login button The short answer is yes. The long answer follows: Add a filter hook in your functions.php or elsewhere like so: > add_filter(‘cbmm_login_filter’, ‘name_of_your_function’, 10, 1); Your function will receive one argument, which is an associative array with three items: url, text, and full. The ‘url’ item contains the url to the OAuth2 handler for the plugin, you should not modify this. The ‘text’ item contains the prompt (“Use Mattermost to login”). The ‘full’ item contains the entire HTML output for the additional Mattermost login section on the WordPress login form. Your function should always return an associative array. If you want to update just the ‘text’ item, simply do so in the array passed to your function and then return the same array. If you want to completely replace the full HTML output, add an item named ‘override’ to the returned array. ### What callback URL do I have to setup on Mattermost The URL should be: https:///wp-content/plugins/mattermost/includes/cbmm-oauth2. php If your `wp-content/plugins` is not in a standard place, then you will need to replace that with the correct URL to it. ## Reviews ![](https://secure.gravatar.com/avatar/cfbd2f063efd6fed5805e7cf96f1710ca2ebacc9ba594924abe39431684e1f45? s=60&d=retro&r=g) ### 󠀁[Great plugin](https://wordpress.org/support/topic/great-plugin-28805/)󠁿 [jarven](https://profiles.wordpress.org/jarven/) aviento 2, 2020 I manage a lot of WordPress sites and this plugin really help me.
