Recording Studio

Record, upload, or generate a greeting.

Drop-in widget. Load https://webforms.dropcowboy.com/latest/dropcowboy-recording-studio.min.js and pass it a site token your server mints. Do not rebuild the recorder, file upload, or text-to-speech step; the widget already does it.

When to use this vs REST

Use Recording Studio when a user records, uploads, or generates a greeting in your app. Use POST /media/public/media to upload a file you already have from a server.

Do not rebuild

A microphone recorder or upload widget.
Text-to-speech generation inside the recorder.

Drop-in

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: ['media'], 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":["media"],"ttl_seconds":900}'

Load the script, init with the token, and call a method:

<script src="https://webforms.dropcowboy.com/latest/dropcowboy-recording-studio.min.js"></script>
<script>
(async function () {
  const minted = await fetch('/dropcowboy/token', { method: 'POST' }).then(function (r) { return r.json(); });
  await DropCowboy.studio.init({ token: minted.token });
  DropCowboy.studio.setTheme({ theme: 'LIGHT', primaryColor: '#009efb' });
  document.getElementById('record-greeting').addEventListener('click', function () {
    DropCowboy.studio.open();
  });
})();
</script>

From your server

Already have the audio file? Skip the widget and store it from your server with an API key that has media:write. Pass ext when the file is not a WAV.

Upload a greeting you already have:

curl -X POST https://api-v2.dropcowboy.com/media/public/media \
  -H "x-key: $KEY" -H "x-secret: $SECRET" \
  -H "Content-Type: application/json" \
  -d '{"url":"https://files.example.com/greeting.mp3","ext":".mp3","name":"Greeting"}'

JS API / HTML tag

Method	What it does
`init({ token })`	Site token with media scope.
`setTheme({ theme, primaryColor })`	LIGHT/DARK plus accent.
`open(options)`	Opens the studio UI.
`addErrorListener(fn) -> stop`	Fires on upload or encode errors.
`close()`	Closes the studio.

Auth and scopes

Site token with the media scope. Your API secret stays on your server.

Site token scope: media. 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.
To store a file you already have on a server, skip the widget and upload with POST /media/public/media.

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

POST /media/public/media - upload a recording by URL
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 Recording Studio

<script src="https://webforms.dropcowboy.com/latest/dropcowboy-recording-studio.min.js"></script>
<script>
(async function () {
  const minted = await fetch('/dropcowboy/token', { method: 'POST' }).then(function (r) { return r.json(); });
  await DropCowboy.studio.init({ token: minted.token });
  DropCowboy.studio.setTheme({ theme: 'LIGHT', primaryColor: '#009efb' });
  document.getElementById('record-greeting').addEventListener('click', function () {
    DropCowboy.studio.open();
  });
})();
</script>

Mint a site token (your server)

// 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: ['media'], 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 });
});

Mint a site token (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":["media"],"ttl_seconds":900}'

Upload a greeting you already have

curl -X POST https://api-v2.dropcowboy.com/media/public/media \
  -H "x-key: $KEY" -H "x-secret: $SECRET" \
  -H "Content-Type: application/json" \
  -d '{"url":"https://files.example.com/greeting.mp3","ext":".mp3","name":"Greeting"}'
