# Slack Specific Variables

As part of FlowBridge Connect functionality, we will populate your flow with specific variable that you can use at your own will. All you need to do is create the variable name in Voiceflow and FlowBridge Connect will automatically populate them with information

Here are the Slack specific variables you can create:

| Variable Name     | Value  | Description                                                                          |
| ----------------- | ------ | ------------------------------------------------------------------------------------ |
| user\_name        | String | The first name of the user's account.                                                |
| user\_id          | String | Slack session ID (user ID for DMs, channel ID for @mentions)                         |
| channel           | String | the channel the user is communicating on. It will be "slack" for Slack conversations |
| channel\_user\_id | String | Slack user ID (e.g., `U01234ABCD`)                                                   |
