Create a customer in Square when a contact’s details change in Brevo

What each client fills in

Nothing. It needs only the accounts it connects to.

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.

• Brevo

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

• Square

  developer.squareup.com → the client’s application (their own account) → Credentials → Production access token. A personal access token for the client’s own account needs no Square review.

After you install it

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

1. Connect the client’s Brevo, for “A contact’s details change”
2. Connect the client’s Square, for “Create a customer”
