Why this helps

Some purchases need a durable, formal confirmation, but preparing one by hand adds another task after checkout.

  • Start confirmation mail from a completed checkout.
  • Use a consistent letter PDF you approve.
  • Ground recipient details in a trusted source you specify.

Setup

Build it in a few focused steps.

  • 1Connect Stripe and Docupost once in the Notis portal.
  • 2Create an automation in Automations, New Automation, and give it a name.
  • 3Describe the purchase confirmation letter in one instruction, including the PDF and trusted address source.
  • 4Pick the Stripe Checkout Session Completed trigger and choose where run reports go.
  • 5Test with one real completed checkout and confirm recipient and document details before sending.

Questions about this workflow

Does the checkout event indicate which purchases need a letter?

The event description only says the checkout session completed. Describe any criteria Notis should apply using data that is actually available.

Can this serve as a receipt?

Use a document whose contents meet your intended purpose. The workflow sends your supplied PDF; it does not create or validate receipt content.
