Cue Ko-fi webhook handling with a Slack reaction
Mark a message ready with a reaction and keep the payment handoff lightweight.
Trigger
Message Reaction Added
Triggered when a reaction is added to a message in Slack. Supports optional filtering by channel and emoji name.
Action
Receive Ko-fi payment webhook
Receives and validates Ko-fi payment webhook events. Use this to process real-time notifications for donations, subscriptions, commissions, and shop orders from Ko-fi. The webhook includes payment details, supporter information, and transaction metadata. Returns validated payment data to confirm receipt (Ko-fi expects 200 OK to prevent retries).
Why this helps
A multi-step approval conversation creates extra mental overhead for a small team.
- Use an existing team signal to cue the next step.
- Avoid adding a separate manual handoff for every payment note.
- Keep handling aligned with the message the team reacted to.
Setup
Build it in a few focused steps.
- 1Connect Slack and Ko-fi to Notis once through the portal.
- 2Create an automation in the portal or ask Notis to draft it conversationally.
- 3Describe in one plain-language instruction which reacted-to payment notes should cue Ko-fi webhook receipt and validation.
- 4Select the Slack reaction added trigger and choose a channel for run reports.
- 5Test with one real message and the intended reaction.
Questions about this workflow
Can the trigger be limited to a reaction or channel?
The reaction trigger supports optional filtering by channel and emoji name.
