Connect Slack

Connect your Slack workspace to share receipts and documents directly to your Midday inbox. Great for teams where receipts often come through Slack.

How it works

Once connected:

1. Share any file to a designated Slack channel
2. The file appears in your Midday inbox
3. AI processes and attempts to match it to transactions
4. Review and confirm matches as usual

Connect Slack

1. Go to Inbox → Settings
2. Find Slack in the integrations section
3. Click Connect Slack
4. Authorize Midday to access your workspace
5. Select or create a channel for receipts

Choose a channel

You can use:

• An existing channel: Use a channel your team already shares receipts in
• A new channel: Create a dedicated #receipts or #expenses channel

Only files shared in the connected channel will be sent to Midday.

Sharing files

Once connected, sharing is simple:

1. Open Slack
2. Go to the connected channel
3. Share a file (drag and drop, or use the attachment button)
4. The file automatically appears in your Midday inbox

Supported files

• Images (photos of receipts)
• PDFs (digital receipts, invoices)
• Common document formats

What happens next

1. The file appears in your Inbox
2. AI extracts merchant, amount, and date
3. Matching against transactions begins
4. You'll see it as "pending" or "suggested match"

Use cases

Team expense capture

Multiple team members can share receipts to one channel. All receipts flow into the same Midday inbox for processing.

Mobile receipt capture

Take a photo of a receipt on your phone, share it to Slack, and it's in Midday—no need to open the Midday app.

Vendor communication

If vendors send receipts or invoices via Slack, forward them to the connected channel.

Multiple workspaces

If you have multiple Slack workspaces, you can connect one per Midday team. Switch teams in Midday to manage different workspace connections.

Disconnect Slack

To stop the integration:

1. Go to Inbox → Settings
2. Find the Slack connection
3. Click Disconnect

Files already in your inbox remain; new files won't sync.

Troubleshooting

Files not appearing in Midday

• Verify the file was shared in the connected channel
• Check that the Slack connection is still active
• Try sharing a different file to test

Can't find the channel

• Make sure you have permission to access the channel
• The channel must be one Midday was authorized to access

Reconnecting

If the connection breaks:

1. Go to Inbox → Settings
2. Click Reconnect next to Slack
3. Re-authorize the connection

Privacy and permissions

• Midday only receives files shared in the connected channel
• We can't read other channels or direct messages
• The integration is read-only—Midday can't post to Slack
• You can disconnect anytime
