#### **Before you start**

2\. Click **Settings** > click **Integration icon** on the left side bar > enable **Sendinblue** > click on its name

### 🔧 Troubleshooting

#### &#x20;“Authentication failed” / “Invalid API key”

* Double-check you pasted the Brevo (Sendinblue) API key (not SMTP key, not a different token).
* Make sure there are no extra spaces before/after the key.
* If it still fails, create a new API key in Brevo and update it in Powerful Form. (Old keys may be revoked.)

#### &#x20;Contacts are not being added to Brevo

* Confirm the integration is enabled on the correct form (you might be editing a different form).
* Make sure you clicked Save after mapping.
* Verify the form submission includes a valid email address.
* Check you selected the correct Brevo List in the integration settings.

#### &#x20;Some fields are empty in Brevo

Re-check your field mapping.

Example: mapping “Full name” into a “First name” field can look “empty” depending on how Brevo displays it.
