Capture receipt data from Slack channel posts
Keep expense paperwork moving by processing receipt files right from the channel where your team shares them.
Trigger
Channel Message Received
Triggers when a message is posted in a channel or group conversation, but not a direct message.
Action
Receipt OCR V3
Extract structured data from receipt images or PDFs.
Why this helps
Receipt attachments get mixed into channel chatter, leaving totals and merchant details for someone to transcribe later.
- Turn shared receipt files into structured data.
- Make receipt details easier to review in context.
- Cut repeated file opening and manual transcription.
Setup
Build it in a few focused steps.
- 1Connect Slackbot and Eagle doc once in the Notis portal.
- 2Create an automation in Automations, New Automation, and name it for channel receipt capture.
- 3Tell Notis to process receipt images or PDFs posted in the selected channel and summarize the result.
- 4Pick Channel Message Received as the trigger and choose where run reports go.
- 5Test with one real channel message containing a receipt.
Questions about this workflow
Can it extract line items and taxes?
Yes. Receipt OCR V3 supports structured receipt output with merchant information, line items, taxes, and payment details.
Can it work on any channel attachment?
Use the instruction to describe receipt files to process. The file must be available to the automation and be an image or PDF Eagle doc can process.
