Why this helps
Receipts can wait because the handoff from sharing a file to asking someone to process it is unclear.
- Creates a lightweight signal that a receipt is ready
- Reduces extra messages needed to hand off a document
- Keeps the action anchored to the receipt conversation
Setup
Build it in a few focused steps.
- 1Connect Slack and Extracta ai once using the Notis portal.
- 2Create an automation through the portal or by asking Notis conversationally.
- 3Write one prompt that starts an Extracta ai extraction when the agreed reaction is added to a Slack message sharing a receipt.
- 4Select Slack Message Reaction Added and choose a channel for run reports.
- 5Test by adding the agreed reaction to a real receipt message.
Questions about this workflow
Can I use any reaction?
Choose a reaction that clearly means the receipt is ready for processing and describe it in the prompt.
Does adding the reaction approve reimbursement?
No. It starts extraction only; approval and reimbursement remain separate decisions.
