Endpoints (4)

POST create-contact

Create or update a contact in Brevo. Provide email and optional attributes (name, etc.).

Field	Type	Required	Description
`email`	email	✓ Yes	Contact email address.
`attributes`	object	No	Contact attributes. Example: {"FIRSTNAME": "John", "LASTNAME": "Doe"}.
`listIds`	array	No	List IDs to add the contact to. Example: [2, 4].

GET list-contacts

List all contacts. Returns email, attributes, and list memberships.

No input parameters required.

POST send-email

Send a transactional email via Brevo SMTP. Supports HTML content and multiple recipients.

Field	Type	Required	Description
`sender`	object	✓ Yes	Sender object. Example: {"name": "My Site", "email": "noreply@example.com"}.
`to`	array	✓ Yes	Recipients array. Example: [{"email": "user@example.com", "name": "User"}].
`subject`	string	✓ Yes	Email subject line.
`htmlContent`	string	✓ Yes	Email body as HTML.
`attachments`	array	No	File attachments: [{ filename, content_base64 }], or [{ filename, asset_slug }] for a file uploaded as an asset of this project (max 1 MB per asset). Prefer asset_slug for static files such as brochures: the file is stored once instead of inline in every form config. Each item needs content_base64 or asset_slug; omitting both returns 422 ATTACHMENT_MISSING_CONTENT. A mime_type key is accepted but ignored for Brevo — this manifest declares no map[type] (see the attachments block below), so the value is dropped and Brevo infers the content type from the file extension.

GET list-campaigns

List email marketing campaigns. Returns name, status, subject, and statistics.

No input parameters required.
