Add a Call button to your own CRM (Cloudflare Workers, Node, PHP, Google Sheets)

Copy-ready recipes for putting a "Call" button next to every phone number in your own CRM, spreadsheet or booking system, safely.

What it means

The safe pattern is always the same: the button in your page asks YOUR server to make the call, and your server calls Silux Call with the API key. The key never reaches the browser.

What it does

• Your page: a Call button sends the number (and who is clicking) to your server.
• Your server: adds the API key and sends POST /api/v1/calls.
• Silux Call: rings the user's extension, then dials the number.

Every part of the page

Cloudflare Worker

Store the key with "wrangler secret put SILUX_API_KEY". In your Worker's route: const r = await fetch("https://www.siluxcall.co.uk/api/v1/calls", { method: "POST", headers: { Authorization: "Bearer " + env.SILUX_API_KEY, "Content-Type": "application/json" }, body: JSON.stringify({ email: user.email, to: number }) }); return new Response(await r.text(), { status: r.status, headers: { "Content-Type": "application/json" } });

Node.js (Express)

app.post("/call", async (req, res) => { const r = await fetch("https://www.siluxcall.co.uk/api/v1/calls", { method: "POST", headers: { Authorization: "Bearer " + process.env.SILUX_API_KEY, "Content-Type": "application/json" }, body: JSON.stringify({ email: req.user.email, to: req.body.to }) }); res.status(r.status).json(await r.json()); });

PHP

$ch = curl_init("https://www.siluxcall.co.uk/api/v1/calls"); curl_setopt_array($ch, [CURLOPT_POST => true, CURLOPT_RETURNTRANSFER => true, CURLOPT_HTTPHEADER => ["Authorization: Bearer " . getenv("SILUX_API_KEY"), "Content-Type: application/json"], CURLOPT_POSTFIELDS => json_encode(["extension" => "1001", "to" => $number])]); $reply = curl_exec($ch);

Python

requests.post("https://www.siluxcall.co.uk/api/v1/calls", headers={"Authorization": "Bearer " + os.environ["SILUX_API_KEY"]}, json={"extension": "1001", "to": number})

Google Sheets (Apps Script)

function callNumber(to) { const key = PropertiesService.getScriptProperties().getProperty("SILUX_API_KEY"); UrlFetchApp.fetch("https://www.siluxcall.co.uk/api/v1/calls", { method: "post", contentType: "application/json", headers: { Authorization: "Bearer " + key }, payload: JSON.stringify({ email: Session.getActiveUser().getEmail(), to: to }) }); } — add a custom menu that calls callNumber() with the selected cell.

The button in your page

<button onclick="fetch('/call', { method: 'POST', headers: { 'Content-Type': 'application/json' }, body: JSON.stringify({ to: '01632960123' }) })">Call</button> — it talks to YOUR server only, never to Silux Call directly.

How to use it

Recommended settings

• ★Check in your server that the person clicking is allowed to make calls, before calling the API.
• ★Send the user's email so each person rings their own extension.
• ★Show the reply's "message" to the user.

API key

A secret password that lets one piece of software use another. Treat it like a password.

Example: Treat an API key like a password: anyone with it can use your account's API.

CRM — Customer Relationship Management

Software that holds your customer records, such as HubSpot, Salesforce, Zoho or Pipedrive.

Example: HubSpot, Salesforce and Zoho are CRMs.

Webhook

An automatic message our system sends to a web address you choose whenever something happens, such as a call ending. Used to connect other software.

Example: When a call ends, a webhook sends its details to your own system automatically.
