Bring Slack context into a VAT identifier review
Start a 44API VAT check and have Notis retrieve the Slack conversation that may explain the company, request, or follow-up.
Trigger
Webhook received
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Action
Fetch conversation history
Fetches a chronological list of messages and events from a specified slack conversation, accessible by the authenticated user/bot, with options for pagination and time range filtering.
Why this helps
VAT checks can arrive without the context that explains who requested them or what the team already discussed.
- See relevant Slack discussion alongside the verification request.
- Reduce channel searching before deciding what to do with a VAT check.
- Keep verification context close to the work already happening in Slack.
Setup
Build it in a few focused steps.
- 1Connect 44API and Slack to Notis once in the portal.
- 2Create an automation in Automations, New Automation, and name it.
- 3In one instruction, tell Notis to use the webhook request context to identify and fetch the relevant Slack conversation for the VAT check.
- 4Choose the webhook trigger and select where run reports should go.
- 5Test with one real VAT check request and confirm the retrieved conversation is relevant.
Questions about this workflow
Does 44API start this automatically?
No. 44API has no trigger events in this package. A Notis webhook starts the automation when an HTTP request reaches it.
Does fetching a Slack conversation verify the VAT number?
No. The Slack action retrieves conversation history. Use the 44API verification result as the source for the identifier check.
What if the request does not identify a Slack conversation?
Notis should report that the context is missing and avoid guessing which conversation to retrieve.
