# Authmatech Developer Docs: Silent Mobile Identity Verification

> Verify customers instantly with silent, no-OTP mobile identity. Integrate Authmatech Verify, Trust, Shield, Detect, and more through one REST API.

Welcome to the Authmatech developer documentation. Authmatech confirms your customer's mobile identity quietly in the background — no codes to wait for, no apps to switch to, no steps that lose customers. Replace the SMS OTP wherever it lives in your product and add real identity intelligence to every customer decision.

Everything runs through a single REST API at `https://service.authmatech.com`, authenticated with your `X-API-KEY` and `X-CLIENT-ID` headers.

## Get up and running in three steps

<Steps>
  <Step title="Get your credentials">
    Sign in to the [Authmatech dashboard](https://dashboard.authmatech.com) and copy your **Client ID** and **API key**. The API key is shown once at generation — store it securely.
  </Step>

  <Step title="Confirm a mobile identity">
    Call `POST /v1/api/verify` from your backend with the `X-API-KEY` and `X-CLIENT-ID` headers. You get back a simple `validNumber` decision — no OTP sent, no code typed.
  </Step>

  <Step title="Add intelligence to the decision">
    Layer in [Trust](/guides/trust-shield-detect), [Shield](/guides/trust-shield-detect), and [Detect](/guides/trust-shield-detect) to score risk, approve trusted customers faster, and surface anomalies — all from the same session.
  </Step>
</Steps>

<Tip>
  Not ready to go live? Authmatech provides a sandbox so you can build and test your integration before sending production traffic. See [Testing & environments](/guides/testing).
