Send a template email in Postmark when a new order comes in to Shopify

What each client fills in

Postmark: From address

For example hello@northside.example

Postmark: Template alias

Postmark → Templates → the template: its alias.

The accounts it needs

Each is the client’s own, stored encrypted and never copied between clients. Until one is added the client’s checklist shows it, and nothing runs.

• 

  Only for a store that already has an admin-created custom app. In the client’s Shopify admin: Apps → Develop apps → the app: its Admin API scopes must include write_customers and read_orders; the token is under API credentials (shown once when it is made; if it is no longer shown, generate a new one).

• 

  Postmark → the client’s server → API Tokens → copy the Server API token. The From address must be a confirmed sender signature or on a verified domain.

After you install it

It lands switched off. The client’s checklist holds exactly this:

1. Connect the client’s Shopify, for “A new order comes in”
2. Connect the client’s Postmark, for “Send a template email”
3. Fill in Postmark: From address (For example hello@northside.example)
4. Fill in Postmark: Template alias (Postmark → Templates → the template: its alias)
