Send SMS text and bulk messages via TelTel.io API

Use the bundled Node scripts to send SMS via the TelTel API.

Before you use the skill (TelTel prerequisites)

1) Register at https://www.teltel.io/

2) Add funds / credit to your TelTel account

3) From the TelTel SMS section, send a test SMS first to confirm your sender name/phone is accepted/verified

4) In TelTel Settings, find your API key

5) Enjoy

Configure from the OpenClaw Skills panel

API key field (shown in the Skills UI)

This skill declares TELTEL_API_KEY as its primary env var, so the OpenClaw Skills UI can show an API key input for it.

Under the hood it maps to:

• skills.entries.teltel-send-sms-text-message.apiKey → TELTEL_API_KEY

Default sender

Set a default sender name/number (used when you do not pass --from):

• skills.entries.teltel-send-sms-text-message.env.TELTEL_SMS_FROM

Configure via environment variables (alternative)

• TELTEL_API_KEY (required)
• TELTEL_SMS_FROM (optional) — default sender name/number
• TELTEL_BASE_URL (optional) — defaults to https://api.teltel.io/v2

Send a single SMS

node {baseDir}/scripts/send_sms.js \
  --to "+3712xxxxxxx" \
  --message "Hello from TelTel" \
  --from "37167881855"

If you omit --from, the script uses TELTEL_SMS_FROM.

Dry-run (prints URL + payload, does not send):

node {baseDir}/scripts/send_sms.js \
  --dry-run \
  --to "+37111111111" \
  --message "test" \
  --from "37167881855"

Send bulk SMS

node {baseDir}/scripts/send_sms_bulk.js \
  --from "37167881855" \
  --to "+3712...,+1..." \
  --message "Hello everyone"

The --to list can be comma/newline/semicolon separated.
