Keep donation references connected to Ko-fi webhook handling
Make the next step visible when someone shares a donation detail with the team.
Trigger
Channel Message Received
Triggered when a message is posted in a Slack channel (public, private, or multi-party IM). Does NOT match direct messages.
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
Donation references copied into chat can be forgotten amid other founder work.
- Keep donation follow-up connected to a team-visible message.
- Give the payment detail a consistent handling cue.
- Reduce the need to hold a reminder in working memory.
Setup
Build it in a few focused steps.
- 1Connect Slack and Ko-fi to Notis once through the portal.
- 2Create the automation in the portal or ask Notis in plain language.
- 3In one instruction, explain how a Slack donation reference should cue receipt and validation of the matching Ko-fi webhook.
- 4Pick the Slack channel message trigger and choose where Notis reports runs.
- 5Test with one real donation reference and payment webhook.
