|
|
===
|
|
|
|
**Note:** *The Mattermost setup portion of this document is just a quick guide. See the [official documentation](https://docs.mattermost.com/developer/oauth-2-0-applications.html) for more details.*
|
|
|
|
This guide uses the generic OAuth2 module for compatibility with Mattermost version 5.0 and above.
|
|
|
|
1. Sign-in with an administrator account to your Mattermost instance
|
|
2. Make sure **OAuth 2.0 Service Provider** is enabled in the Main Menu (menu button next to your username in the top left corner) --> System Console --> Custom Integrations menu, which you can find at `https://your.mattermost.domain/admin_console/integrations/custom`
|
|
|
|
|
|
3. Navigate to the OAuth integration settings through Main Menu --> Integrations --> OAuth 2.0 Applications, at `https://your.mattermost.domain/yourteam/integrations/oauth2-apps`
|
|
4. Click on the **Add OAuth 2.0 Application** button to add a new OAuth application
|
|
|
|
|
|
5. Fill out the form and click **Save**
|
|
|
|
|
|
*Note: The callback URL is \<your-codimd-url\>/auth/oauth2/callback*
|
|
|
|
6. After saving the application, you'll receive the Client ID and Client Secret
|
|
|
|
|
|
7. Add the Client ID and Client Secret to your config.json file or pass them as environment variables
|
|
* `config.json`:
|
|
```javascript
|
|
{
|
|
"production": {
|
|
"oauth2": {
|
|
"baseURL": "https://your.mattermost.domain",
