Requirements: Admin role; the API key from section 3.
- In Integrations, find the Brevo card (in “Available” state) and click Connect.
- The “Connect Brevo” modal repeats the help from section 3, so you have it at hand without going back to Brevo.
- Paste the API key (v3) into the field.
- Click Connect.
Result: the Platform verifies the key against Brevo for real before saving anything — it doesn’t accept a key with a valid format and nothing more. If verification fails, you’re told the specific error (section 8) and no credential is saved. If it succeeds, the card switches to Connected.
