Simple, predictable responses. No SDKs required. Just HTTP. But if you want one, we have those too.

create-template.js

const response = await fetch('https://api.min8t.com/v1/templates', {
  method: 'POST',
  headers: {
    'MiN8T-Api-Auth': process.env.MIN8T_API_KEY,
    'Content-Type': 'application/json'
  },
  body: JSON.stringify({
    name: 'Welcome Email',
    type: 'promotional',
    folder: 'onboarding'
  })
});

const template = await response.json();
console.log(template.id); // "tmpl_a1b2c3d4"

create_template.py

import requests

response = requests.post(
    'https://api.min8t.com/v1/templates',
    headers={
        'MiN8T-Api-Auth': API_KEY,
        'Content-Type': 'application/json'
    },
    json={
        'name': 'Welcome Email',
        'type': 'promotional',
        'folder': 'onboarding'
    }
)

template = response.json()
print(template['id'])  # "tmpl_a1b2c3d4"

terminal

curl -X POST https://api.min8t.com/v1/templates \
  -H "MiN8T-Api-Auth: YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "name": "Welcome Email",
    "type": "promotional",
    "folder": "onboarding"
  }'

Authentication

One header. That's it.

Authenticate every request with a single API key. No OAuth flows, no token refreshes. Unless you need them.

1

Create a project

Go to Developer Tools and create a new project. Each project gets isolated credentials and rate limits.

2

Generate your API key

Navigate to Projects, then Credentials. Copy your API key. It starts with min8t_

3

Add the header

Include MiN8T-Api-Auth in every request. That's all you need to start building.

TLS 1.3 encryption on all endpoints

Rate limiting per project (configurable)

CORS whitelist for browser integrations

HMAC-SHA256 webhook signatures

request.js

const headers = {
  'MiN8T-Api-Auth': 'min8t_sk_live_a1b2c3...',
  'Content-Type':   'application/json'
};

// Every endpoint uses the same header
const templates = await fetch(
  'https://api.min8t.com/v1/templates',
  { headers }
);

const assets = await fetch(
  'https://api.min8t.com/v1/assets',
  { headers }
);

const verify = await fetch(
  'https://api.min8t.com/v1/verify',
  { method: 'POST', headers,
    body: JSON.stringify({
      email: 'user@example.com'
    })
  }
);
