Custom HTTP gateway setup

1. Find your provider's send-SMS API docs

Every SMS API has a reference page like "Send an SMS" with:

• A URL endpoint (e.g. https://api.provider.com/v1/send)
• HTTP method (usually POST)
• Auth method (API key header, basic auth, or bearer token)
• Request body template (JSON or form-encoded)
• A success response format

2. Go to Notif app → Gateways → Add custom HTTP

Fill in the form:

Name

Pick anything — "FastSMS Primary" or "MyProvider Transactional".

Endpoint

Full URL from docs.

Method

Usually POST.

Headers

One key=value per line. Example:

Content-Type: application/json
Authorization: Bearer YOUR_API_KEY

Body template

Use {{to}}, {{text}}, {{from}} as placeholders. Alintro fills these per-message. Example (JSON):

{
  "to": "{{to}}",
  "from": "{{from}}",
  "text": "{{text}}",
  "dlt_template_id": "1234567890123456789"
}

Form-encoded is also supported — Alintro detects the Content-Type header.

Success matcher

A substring that tells Alintro the send succeeded. Examples:

• "status":"success" (MSG91)
• "queued" (Twilio)
• "return_code":201

3. Test

Click Test connection. Alintro sends a test message to your admin phone. On failure, the raw HTTP response is shown so you can debug.
