Tajo connects to Brevo using an API key. This takes about 10 minutes and only needs to be done once per store.
You will need
- ✅ A Brevo account (Free or paid)
- ✅ Admin access to your Tajo account
Step 1: Generate the Key in Brevo
- Log in to Brevo.
- Open the account menu (top right) and go to SMTP & API.
- Select the API Keys tab.
- Click Generate a new API key, name it
Tajo, and copy the key.
Copy the key immediately. Brevo only shows it once.
Step 2: Add the Key to Tajo
- In Tajo, go to Settings > Connections > Brevo.
- Paste the API key and save.
- Tajo validates the key and confirms the connection.
Step 3: Confirm It Works
After saving, Tajo runs a test call. A green status means the key is valid and the sync can begin. If you see an error, see Troubleshooting below.
Security Best Practices
- Use a dedicated key named
Tajoso you can revoke it without affecting other integrations. - Never share the key or paste it into client-side code.
- Rotate the key periodically: generate a new one, update it in Tajo, then delete the old one in Brevo.
Troubleshooting
- “Invalid API key”: the key was copied with a trailing space or is from the wrong Brevo account. Regenerate and paste again.
- “Unauthorized”: the Brevo plan or user role lacks API access. Use an admin-level Brevo user.
- Connection drops later: the key was deleted or rotated in Brevo. Generate a new one and update it in Tajo.
Next: connect Shopify to Brevo.
