Send SMS text and bulk messages via TelTel.io API

Send SMS text messages via TelTel (teltel.io) using the REST API (api.teltel.io). Includes bulk send, delivery report, and bulk sms.

openclaw skills install @teltel-call-center/teltel-send-sms-text-message

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

Before you use the skill (TelTel prerequisites)

Register at https://www.teltel.io/
Add funds / credit to your TelTel account
From the TelTel SMS section, send a test SMS first to confirm your sender name/phone is accepted/verified
In TelTel Settings, find your API key
Enjoy

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:

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

bash

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):

bash

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

bash

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

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