Send an email in Brevo when a payment fails in Stripe

What each client fills in

Brevo: 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.

• 

  In the client’s Stripe dashboard: Developers → API keys → Create restricted key. Give it only what the steps need: Customers write, Payment Links write, Prices read, Invoices write, and Webhook Endpoints write for the triggers. Leave “IP access” empty: Thrum has no fixed addresses, so a key locked to IPs fails every call.

• Brevo

  In the client’s Brevo: account menu → SMTP & API → API Keys → Generate a new API key.

After you install it

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

1. Connect the client’s Stripe, for “A payment fails”
2. Connect the client’s Brevo, for “Send an email”
3. Fill in Brevo: From address (For example hello@northside.example)
