# Create a Slack or Discord integration

POST https://api.modulards.com/api/public/v1/alerts/{alert_id}/integrations
Content-Type: application/json

Creates the Slack or Discord destination of a notification configuration. If the configuration already has a destination of that type, its URL is replaced instead and the destination keeps its id. It never sends a test message and never switches the channel on: that is `slack_channel` or `discord_channel` on "Update a notification configuration".

A destination has no request of its own to read it: read it with "Retrieve a notification configuration" and `include=integrations`. The complete URL is returned on ordinary reads too. To change the URL of an existing destination use "Update a Slack or Discord integration", and to remove it "Delete a Slack or Discord integration".

Your role must be allowed to edit notification configurations and the organization's plan must include the channel; otherwise the request answers 404. The body is checked before the configuration, so an invalid body answers 422 and a configuration of another organization answers 404 only when the body is valid.

**Body**
- `type` (`slack` or `discord`, required): the kind of destination.
- `url` (string, required): at most 2048 characters, a complete `https://hooks.slack.com/services/...` URL for `slack`, or a complete `https://discord.com/api/webhooks/...` (or `discordapp.com`) URL for `discord`.

**Errors**
- **422**: `type` is not `slack` or `discord`, or `url` is empty, masked or not valid for the type.
