Integrations

Connect third-party services used by automations and DNS workflows — Twilio for SMS steps, plus Vercel and related account integrations for domain tooling.

Base URL: https://api.supersendtx.com

Auth: Bearer stx_… full-access API key (or dashboard session cookie). Sending-scoped keys cannot manage integrations.

Twilio (SMS)

Required before send_sms automation steps will deliver.

PUT /integrations/twilio

Validates Account SID + Auth Token against Twilio, encrypts them at rest, and stores a default from number and/or Messaging Service SID for send_sms steps.

SUPERSENDTX_API_KEY=stx_… npx -y --package=supersendtx-cli -- supersendtx integrations twilio connect \
  --account-sid AC… \
  --auth-token … \
  --from +15551234567

Or set env vars and omit flags:

export TWILIO_ACCOUNT_SID=AC…
export TWILIO_AUTH_TOKEN=…
export TWILIO_DEFAULT_FROM=+15551234567
supersendtx integrations twilio connect

Use --messaging-service-sid MG… instead of --from when you send via a Twilio Messaging Service.

npm

import { SuperSendTX } from 'supersendtx'

const client = new SuperSendTX('stx_…')

await client.integrations.connectTwilio({

  authToken: '…',

})

const { twilio } = await client.integrations.getTwilio()
console.log(twilio.connected)
