LessOTP SDKs

Official client libraries for the LessOTP Inbound Phone Authentication API (WhatsApp by default, Telegram supported).

Install

Runtime	Package	Install

Surface

Each SDK uses one auth request method. The endpoint is selected by the client environment:

• production (default) → POST /api/v1/auth/request
• staging → POST /api/v1/staging/auth/request

Per-call environment overrides are also supported.

const client = new LessOTPClient({ apiKey: "..." }); // production
await client.authRequest("6281234567890");
await client.authRequest(undefined); // frictionless
await client.authRequest("6281234567890", { environment: "staging" });

Common helpers:

verifyWebhookSignature(raw, header, secret)
parseVerifiedWebhook(raw, header, secret)
