Send a capture to Slack

Quick Capture for Slack

Get the words down in Capture, then hand them to Slack when you are ready to share. Post a Capture as a message to a Slack channel through an incoming webhook, with optional link and media previews.

To send a capture to Slack, open Capture Settings, choose Export, and add Slack as a destination. Create a Slack app at api.slack.com/apps, turn on Incoming Webhooks, and add a webhook for a channel. Copy the webhook URL and paste it into Capture; it is required before the destination can be saved. Text and phone captures become the message text. Links become a Slack link that shows the fetched page title when available, otherwise the bare URL. Slack is offered as a destination for Text and Links captures.

A quick capture workflow for Slack

  2. 02Keep moving

    Save the Capture without stopping to organize the destination.

  3. 03Send to Slack

    Use your configured export action when the capture is ready.

What gets sent to Slack

  • Text and phone captures become the message text.
  • Links become a Slack link that shows the fetched page title when available, otherwise the bare URL.
  • Capture escapes <, > and & so Slack does not read them as links or mentions.
  • The Link previews and Media previews settings are sent with every message.

Set up Slack in Capture

  1. Open Capture Settings, choose Export, then tap Configure if this is your first destination or Add new destination.
  2. Choose Slack from the app picker.
  3. Create a Slack app at api.slack.com/apps, turn on Incoming Webhooks, and add a webhook for a channel.
  4. Copy the webhook URL and paste it into Capture; it is required before the destination can be saved.
  5. Review the destination name and icon, then tap Save.

Example: a quick capture to Slack

Add a webhook for your #reading channel and paste its URL into Capture. Exporting an article link posts a message in that channel with the page title as the link text.

Send the capture

  1. Open an existing Capture and choose its configured Slack export action.
  2. Capture hands off only the supported types listed above. Complete any confirmation or compose screen shown by Slack.

Limits and troubleshooting

Limits

  • Images and files are unsupported.
  • Messages go to the channel the webhook was created for; Capture has no channel field.
  • The message is posted through the webhook without opening Slack.

Troubleshooting

  • If Capture rejects the destination, paste the full webhook URL that starts with https://hooks.slack.com/services/.
  • If the export fails, read the error text Capture shows, then copy the webhook URL again from your Slack app settings.
