Click-to-Text

A button that starts an SMS to your business number.

Drop-in widget. Load https://webforms.dropcowboy.com/latest/dropcowboy-click-to-text.min.js and pass it a site token your server mints. Do not rebuild the compose box or the send flow; the widget already does it.

When to use this vs REST

Use Click-to-Text for a button that starts a text thread with your business. Use POST /sms to text from your server.

Do not rebuild

  • The compose box and send flow.

Drop-in

  1. On your server, trade your API key for a short-lived site token (the key needs numbers:write):
// Your server. Browser code never sees KEY/SECRET.
app.post('/dropcowboy/token', async function (req, res) {
  const r = await fetch('https://api-v2.dropcowboy.com/phone/public/embed/token', {
    method: 'POST',
    headers: {
      'x-key': process.env.DC_KEY,
      'x-secret': process.env.DC_SECRET,
      'Content-Type': 'application/json'
    },
    body: JSON.stringify({ site_id: process.env.DC_SITE_ID, scope: ['dialer:webrtc'], ttl_seconds: 900 })
  });
  const body = await r.json();
  if (!r.ok) return res.status(r.status).json(body);
  // The API wraps results in data. Hand the browser just the token.
  res.json({ token: body.data.token, expires_at: body.data.expires_at });
});

Or test the mint with cURL:

# On your server: trade your API key (needs numbers:write) for a site token. 1 hour max.
curl -s -X POST https://api-v2.dropcowboy.com/phone/public/embed/token \
  -H "x-key: $KEY" -H "x-secret: $SECRET" \
  -H "Content-Type: application/json" \
  -d '{"site_id":"YOUR_SITE_ID","scope":["dialer:webrtc"],"ttl_seconds":900}'
  1. Load the script, init with the token, and call a method:
<script src="https://webforms.dropcowboy.com/latest/dropcowboy-click-to-text.min.js"></script>
<script>
(async function () {
  const minted = await fetch('/dropcowboy/token', { method: 'POST' }).then(function (r) { return r.json(); });
  await DropCowboy.clickToText.init({ token: minted.token });
  DropCowboy.clickToText.setTheme({ theme: 'LIGHT', primaryColor: '#009efb' });
  document.getElementById('text-us').addEventListener('click', function () {
    DropCowboy.clickToText.sendMessage('+15125550100', {
      body: 'Hi, I have a question about pricing.',
      consentId: window.lastConsentId
    });
  });
})();
</script>

JS API / HTML tag

Method What it does
init({ token, number }) Default business DID.
setTheme({ theme, primaryColor }) LIGHT/DARK plus accent.
sendMessage(to, { body, consentId }) Sends the SMS. consentId is required.
addMessageListener(fn) -> stop Fires after a queued send.
addErrorListener(fn) -> stop Fires on send errors.
close() Tears down the session.

HTML tag:

<dc-click-to-text number="+15125550100" prefill="Hi"></dc-click-to-text>

Auth and scopes

Site token. Your API secret stays on your server.

Site token scope: dialer:webrtc. Mint it with POST https://api-v2.dropcowboy.com/phone/public/embed/token using an API key with numbers:write. Tokens last up to one hour.

Limits

  • Site tokens last at most one hour (the default). Mint a fresh one per page load or session; do not cache one across users.
  • Calls and texts need a connected carrier (BYOC) and prepaid balance. Without them the mint returns 402 or 403 for telephony scopes.
  • Outbound SMS needs a consent_id captured with Consent Capture for that phone number.

Routes are on https://api-v2.dropcowboy.com.

  • POST /sms - send a text from your server
  • POST /phone/public/embed/token - mint the site token

Copy the code

The snippets on this page. Your server keeps the API key pair (KEY and SECRET for curl, DC_KEY and DC_SECRET for Node); the browser only sees the short-lived site token.

Load the Click-to-Text

  DropCowboy.clickToText.setTheme({ theme: 'LIGHT', primaryColor: '#009efb' });
  document.getElementById('text-us').addEventListener('click', function () {
    DropCowboy.clickToText.sendMessage('+15125550100', {
      body: 'Hi, I have a question about pricing.',
