Quickstart

From signup to first sent email in five minutes.

1. Get an API key

In the dashboard at mailinfra.ru/emails open Project → API keys → Create key. Copy the displayed token — you can't retrieve it again.

• mi_test_… — sandbox, no domain verification, no real delivery.
• mi_live_… — production, requires a verified domain.

Start with mi_test_… — it's the fastest way to validate the integration.

2. Send an email

All requests authenticate via the Authorization: Bearer <key> header.

cURL

curl -X POST https://api.mailinfra.ru/v1/emails \
  -H "Authorization: Bearer mi_test_xxxxxxxx" \
  -H "Content-Type: application/json" \
  -d '{
    "from": "hello@example.com",
    "to": ["you@example.com"],
    "subject": "Hello from MailInfra",
    "html": "<p>Hello!</p>"
  }'

Python

import httpx

response = httpx.post(
    "https://api.mailinfra.ru/v1/emails",
    headers={"Authorization": "Bearer mi_test_xxxxxxxx"},
    json={
        "from": "hello@example.com",
        "to": ["you@example.com"],
        "subject": "Hello from MailInfra",
        "html": "<p>Hello!</p>",
    },
)
data = response.json()["data"]
print(data["id"], data["status"])

TypeScript

const res = await fetch("https://api.mailinfra.ru/v1/emails", {
  method: "POST",
  headers: {
    Authorization: "Bearer mi_test_xxxxxxxx",
    "Content-Type": "application/json",
  },
  body: JSON.stringify({
    from: "hello@example.com",
    to: ["you@example.com"],
    subject: "Hello from MailInfra",
    html: "<p>Hello!</p>",
  }),
});
const { data } = await res.json();
console.log(data.id, data.status);

Response:

{
  "data": {
    "id": "018e1b7a-1111-7000-aaaa-111111111111",
    "status": "SIMULATED",
    "skipped_recipients": []
  }
}

SIMULATED means sandbox — no real delivery. With mi_live_… and a verified domain you'll get QUEUED → DELIVERED.
