Generate ready-to-use code snippets for popular SMS APIs — Twilio, MSG91, Fast2SMS, Textlocal, or your custom API.
Security: For security, run these commands from your terminal or backend server, not from the browser. Your API keys are never stored or sent to our servers — all code is generated client-side.
curl -X POST 'https://api.twilio.com/2010-04-01/Accounts/YOUR_ACCOUNT_SID/Messages.json' \ -u 'YOUR_ACCOUNT_SID:YOUR_AUTH_TOKEN' \ -d 'To=%2B1234567890&From=%2B1234567890&Body=Hello%20from%20Twilio!'
The SMS API Code Generator turns your message parameters into ready-to-paste code for three popular SMS gateways: Twilio, MSG91, and Fast2SMS. You fill in the fields each provider needs, such as sender ID or Twilio 'from' number, recipient number in E.164 format, message body, and the provider credentials (Twilio Account SID and Auth Token, or the MSG91/Fast2SMS auth key), and the tool emits a working request in the language and client you choose.
It is built for backend and full-stack developers wiring transactional or OTP SMS into an app without reading three different API references first. Instead of hand-writing the REST call, you get correct endpoint URLs, headers, HTTP method, and body encoding (form-encoded for Twilio, JSON or query params for MSG91 and Fast2SMS) as a curl command, Node.js, Python, or PHP snippet you can drop straight into your project.
Each provider exposes an HTTP endpoint and the tool assembles a correct request for it. Twilio uses a POST to https://api.twilio.com/2010-04-01/Accounts/{AccountSID}/Messages.json with HTTP Basic auth (the Account SID as username, Auth Token as password) and a form-urlencoded body containing To, From, and Body. MSG91 and Fast2SMS use their own REST endpoints, typically authenticated with an authkey header or query parameter and a JSON or query-string payload carrying the route, sender ID, numbers, and message.
The generator maps your form fields onto each provider's exact parameter names, sets the right Content-Type header, and renders the call in the selected language using its idiomatic HTTP client, for example the twilio SDK or fetch in Node.js, requests in Python, or cURL in PHP. Because Indian SMS routes require DLT (Distributed Ledger Technology) registration under TRAI rules, the MSG91 and Fast2SMS snippets include sender ID and template/route fields so your approved template maps correctly. All snippet generation happens locally in your browser from the values you enter.
No. It only generates the code snippet from your inputs. You run that snippet from your own server or terminal to send the message, so nothing is dispatched from this page.
Yes, it is completely free. The tool runs in your browser and builds the snippet locally from the values you type, so your Auth Token or auth key is not transmitted to or stored on our servers. Still, treat any generated code with credentials as a secret.
It supports Twilio, MSG91, and Fast2SMS, with output in curl, Node.js, Python, and PHP so you can match your project's stack.
Twilio requires E.164 format with a country code, such as +14155552671. MSG91 and Fast2SMS typically accept a plain 10-digit Indian number or one prefixed with 91; use the format your account and route expect.
For sending to Indian numbers, yes. TRAI requires your sender ID (header) and message template to be DLT-registered. The generated snippets include the sender ID and route/template fields so your approved template lines up.
A 401 almost always means the Account SID or Auth Token is wrong, or the 'from' number is not a Twilio number on your account. Confirm both credentials and that the sender number is verified for your account.
No. Use the placeholders and load the SID, Auth Token, or auth key from environment variables or a secrets manager at runtime. Never commit real credentials to source control.
