Add the Brex app to Slack

Account and card admins can add Brex as an authorized Slack app by following these instructions: Step 1: Make sure both of the following are true:

  • You have permission in Slack to install apps into your workspace (being a Slack admin is not required).
  • You have a company expense policy set up first.

Step 2: In your Brex dashboard, navigate to Expenses > Company expenses. Step 3: Click Add to Slack on the banner at the top of the page. Or go to Settings > Expenses > Expense review reminders in Slack > Add to Slack. Step 4: Provide authorization and install the app. Once set up, you’ll see Slack in your Brex dashboard by clicking your name in the top right corner and going to Integrations > Productivity.

Connect Brex to your individual Slack account

If an account or card admin has already set up the Slack connection, you’ll receive an email confirming that you’ve been newly onboarded. You can view the connection in your Brex dashboard in Personal settings > Connected integrations. From here, you can also refresh or disconnect by clicking the three dots in the top right corner. If an account or card admin hasn’t set up the Slack integration, they can do so by going to Settings > Manage my account > Slack > Integrations > Connect. Alternatively, you can open the App section in Slack and search for “Brex.”

Respond to expense messages in Slack

Users will receive Slack messages about all of their transactions that violate your company’s expense policy, particularly regarding missing information like receipts or memos. To resolve the alert, please follow the steps below. Step 1: Reply directly to the Slack message with the missing information: send a receipt image as an attachment or memo as a message. Step 2: When doing this for the first time, grant Slack permission to access your Brex account by signing in to Brex. Step 3: Wait for a confirmation Slack message that the information has been uploaded to Brex.

Muting/unmuting Slack notifications

If you don’t want to be alerted for every Brex notification via Slack, but still want to receive them for later review, you can mute your notifications by following these steps. Step 1: From your desktop Slack application, go to the App section. You may need to click the arrow to see the full list of apps. Step 2: Click Brex > View App Detail. Step 3: Click Brex at the top of the page and choose Mute in the popup window. The button will change to Muted. Click this again to unmute your notifications.
