Review invoice deadlines before they arrive
Get a timely prompt to decide what to do with invoices that are still awaiting attention.
Trigger
Webhook received
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Action
Quick Add Event
Parses natural language text to quickly create a basic google calendar event with its title, date, and time, suitable for simple scheduling; does not support direct attendee addition or recurring events, and `calendar id` must be valid if not 'primary'.
Why this helps
Invoices with deadlines can pass unnoticed when there is no reminder to review them.
- Create a review reminder based on a deadline included in the webhook.
- Set the review lead time and handling rules yourself.
- Use invoice references to make the reminder actionable.
Setup
Build it in a few focused steps.
- 1Connect BTCPay Server and Google Calendar once in the Notis portal.
- 2Create an automation in Automations, New Automation, and name it for invoice review.
- 3Tell Notis which invoice states and deadline lead time should create a reminder.
- 4Choose a Notis webhook trigger and select where run reports should go.
- 5Test with one real invoice notification that includes the relevant deadline.
Questions about this workflow
Can this remind me if no deadline is included?
Only if you supply an alternate timing rule. Otherwise, tell Notis to report that it cannot schedule a deadline-based reminder.
Does the reminder change invoice status?
No. It creates a calendar reminder for you to review the invoice.
