What is Brixus365?

Brixus365 is an email platform for developers and marketing teams. These docs cover the Developer Email API — a REST API for sending transactional email from your application.

Brixus365 has two surfaces:

• Developer Email API — send transactional email programmatically: receipts, password resets, notifications, magic links.
• Dashboard — no-code tools for your marketing team: Spark for broadcast campaigns, Connect for customer conversations and inbox management.

The Developer Email API

The API is JSON over HTTPS. You authenticate with an API key — no SDK required, any HTTP client works.

Base URL	https://app.brixus365.com/api/v1/
Auth	X-API-Key: bx_live_*
Format	JSON request and response bodies
Protocol	HTTPS only

What you can do

Capability	Endpoint
Send a single transactional email	POST /v1/emails/send
Send up to 100 emails in one request	POST /v1/emails/batch
Use a saved or starter template	template_id / starter_template field on send
Check message delivery status	GET /v1/emails/:message_id
List sent messages with filters	GET /v1/emails
Manage sending domains	GET/POST /v1/settings/email-domains
Issue and revoke API keys	GET/POST /v1/settings/api-keys

---

How it works

1. Verify a sending domain — add DNS records to prove you own the domain your emails come from.
2. Get an API key — create a key in Settings → API Keys with the scopes you need.
3. Send — POST /v1/emails/send with your key in X-API-Key.

That’s the core loop. Templates, batching, analytics, and domain management all build on top of it.
