What do I need to get started?

A Brevo account with an API key, and a Bolt project.

Is Brevo in Bolt's integrations list?

No. This is the Brevo API called from a Bolt server function, with your key stored as a secret.

Where do I find my Brevo API key?

In Brevo, under SMTP & API. Create the key there, then add it to Bolt as BREVO_API_KEY.

What happens to my data?

Your API key stays in a Bolt secret, out of front-end code. Read how Brevo handles personal data under the GDPR.

Send Brevo emails and add contacts from Bolt

Store your Brevo API key as a Bolt secret, then ask Bolt for a server function that calls the Brevo API. Welcome emails and list signups, from the same prompt box where you build.

Why connect Brevo to Bolt

One secret to connect

Add your Brevo API key as a secret named BREVO_API_KEY, then ask Bolt to write the server function that calls Brevo.

Start with two calls

Send a transactional email with POST /v3/smtp/email. Add a contact with POST /v3/contacts. Same base URL, same api-key header.

A key that stays off the front end

Bolt Database Secrets hold sensitive values like API keys for your server functions, so your Brevo key never sits in front-end code.

What you can do with Brevo in Bolt

CONTACTS

Add contacts to a list

Ask Bolt for a server function that calls POST https://api.brevo.com/v3/contacts with an email and listIds, so a new signup lands on your Brevo list.
