Send an email in SendGrid when a new order comes in to Shopify

What each client fills in

SendGrid: From address

For example hello@northside.example

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).

• 

  SendGrid → Settings → API Keys → Create API Key with Mail Send access; for the triggers, also the Event Webhook settings permission (user.webhooks.event.settings.read and user.webhooks.event.settings.update), or Full Access. The From address must be a verified sender.

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 SendGrid, for “Send an email”
3. Fill in SendGrid: From address (For example hello@northside.example)
