TableFlow can send notifications to Slack when extractions are completed or fail. This helps your team stay informed about the status of document extractions without constantly checking the dashboard.

​
Setting Up Slack Notifications

​
1. Create a Slack App

First, you’ll need to create a Slack app and configure incoming webhooks:
  1. Go to the Slack API Apps page
  2. Click Create New App
  3. Select From scratch
  4. Enter a name for your app (e.g., “TableFlow Notifications”) and select your workspace
  5. Click Create App
Create Slack App

​
2. Configure Incoming Webhooks

Next, you need to enable and configure incoming webhooks:
  1. In your Slack app settings, click on Incoming Webhooks in the sidebar
  2. Toggle the switch to Activate Incoming Webhooks
  3. Click Add New Webhook to Workspace
Configure Slack App
  1. Select the channel where you want to receive TableFlow notifications
  2. Click Allow to give the app permission to post to the channel
Select Slack Channel
  1. Copy the Webhook URL that appears on the page
Copy Webhook URL

​
3. Configure TableFlow

Now, add the webhook URL to your TableFlow settings:
  1. Navigate to your workspace settings in TableFlow
  2. Select the Webhooks tab
  3. Click Add Endpoint
  4. Paste the Slack Webhook URL from the previous step
  5. Select which events you want to receive notifications for
  6. Click Create
TableFlow Webhook Settings

​
Customizing Notifications

To customize the notification format, you’ll need to use transformations:
  1. Navigate to the Advanced section of the endpoint settings
  2. Toggle on the Enabled switch under Transformations
  3. Click Edit transformation
Enable Transformations
  1. Add your transformation code and click Save
Here’s an example of a transformation for extraction completion notifications: 
function handler(webhook) {
  // Format different messages based on the event type
  if (webhook.event === "extraction.completed") {
    webhook.payload = {
      text: `:white_check_mark: *Extraction Completed*
*File:* ${webhook.payload.file_name}
*Template:* ${webhook.payload.template_name}
*ID:* ${webhook.payload.extraction_id}
*Status:* Completed
*Time:* ${new Date(webhook.payload.updated_at * 1000)
        .toISOString()
        .replace("T", " ")
        .substring(0, 19)} UTC`,
    };
  } else if (webhook.event === "extraction.failed") {
    webhook.payload = {
      text: `:x: *Extraction Failed*
*File:* ${webhook.payload.file_name}
*Template:* ${webhook.payload.template_name}
*ID:* ${webhook.payload.extraction_id}
*Status:* Failed
*Error:* ${webhook.payload.error}
*Time:* ${new Date(webhook.payload.updated_at * 1000)
        .toISOString()
        .replace("T", " ")
        .substring(0, 19)} UTC`,
    };
  }

  return webhook;
}

​
Notification Types

TableFlow can send the following types of notifications to Slack:

​
Extraction Completed

Sent when an extraction has been successfully completed: 
✅ Extraction Completed
File: invoice-2023-04-15.pdf
Template: Invoice Template
ID: uT2bJNWN75YPU95r
Status: Completed
Time: 2023-04-24 14:23:48 UTC

​
Extraction Failed

Sent when an extraction has failed: 
❌ Extraction Failed
File: corrupted-file.pdf
Template: Invoice Template
ID: uT2bJNWN75YPU95r
Status: Failed
Error: Unable to process document: corrupt file
Time: 2023-04-24 14:23:48 UTC

​
Filtering Notifications

For busy workspaces with many extractions, you can set up filters to only receive notifications for specific templates or file types: Example filter to only receive notifications for PDF files: 
function handler(webhook) {
  if (webhook.payload.file_type?.key !== "document") {
    webhook.cancel = true;
    return webhook;
  }

  // Continue with formatting the notification
  webhook.payload = {
    text: `New ${webhook.payload.file_type.key.toUpperCase()} extraction: ${
      webhook.payload.file_name
    }`,
  };

  return webhook;
}
Example filter to only receive notifications for a specific template: 
function handler(webhook) {
  if (webhook.payload.template_id !== "dk4g1tUg1uHLs8YU") {
    webhook.cancel = true;
    return webhook;
  }

  // Continue with formatting the notification
  webhook.payload = {
    text: `New extraction using template: ${webhook.payload.template_name}`,
  };

  return webhook;
}

​
Advanced Notification Formatting

You can create more advanced notifications using Slack’s block kit format: 
function handler(webhook) {
  if (webhook.event === "extraction.completed") {
    webhook.payload = {
      blocks: [
        {
          type: "header",
          text: {
            type: "plain_text",
            text: "✅ Extraction Completed",
            emoji: true,
          },
        },
        {
          type: "section",
          fields: [
            {
              type: "mrkdwn",
              text: `*File:*\n${webhook.payload.file_name}`,
            },
            {
              type: "mrkdwn",
              text: `*Template:*\n${webhook.payload.template_name}`,
            },
          ],
        },
        {
          type: "section",
          fields: [
            {
              type: "mrkdwn",
              text: `*Status:*\nCompleted`,
            },
            {
              type: "mrkdwn",
              text: `*Time:*\n${new Date(webhook.payload.updated_at * 1000)
                .toISOString()
                .replace("T", " ")
                .substring(0, 19)} UTC`,
            },
          ],
        },
        {
          type: "actions",
          elements: [
            {
              type: "button",
              text: {
                type: "plain_text",
                text: "View Extraction",
                emoji: true,
              },
              url: `https://app.tableflow.com/extractions/${webhook.payload.extraction_id}`,
            },
          ],
        },
      ],
    };
  }

  return webhook;
}

​
Troubleshooting

If you’re not receiving Slack notifications:
  1. Check Permissions - Ensure the Slack app has permission to post to the channel
  2. Verify Webhook URL - Confirm the webhook URL is correctly entered in TableFlow
  3. Check Event Configuration - Make sure you’ve enabled the events you want to receive
  4. Test Webhook - Use the “Send Test” button in TableFlow to verify the connection
  5. Check Filters - Ensure you haven’t added filters that might be blocking all notifications
  6. Examine Logs - Check the webhook logs in TableFlow for any errors
