# Sender ID

## Required on send

Every SEND\_SINGLE, SEND\_BULK\_SAME, and SEND\_BULK\_DIFFERENT request includes senderID. It must be approved for your account.

## Registration

Request or manage Sender IDs in the portal. Approval timing depends on network processes — check status in your account rather than assuming a fixed SLA from this page.

## Example usage

senderID appears in both GET and POST examples:

```
curl -X POST \
  "https://portal.velobotix.app/api.php?FUN=SEND_SINGLE" \
  -u "YOUR_EMAIL:YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "senderID": "VeloBotix",
    "to":       "0701234567",
    "msg":      "Your OTP is 483920. Valid for 5 minutes."
  }'
```

## Create account

Sign up in the portal and get your API key — username is your email, password is the key.
