This guide takes you from a fresh account to your first successful verification. By the end, you will have confirmed a mobile identity through the Authmatech API and seen the response your integration is built on. It takes about five minutes.
Authmatech provides a sandbox so you can build and test without affecting production traffic or consuming live balance. See Testing & environments for details.
1

Get your credentials

Sign in to the Authmatech dashboard. Generate your API key and copy two values:
  • Client ID — sent as the X-CLIENT-ID header on every request.
  • API key — sent as the X-API-KEY header on every request.
Your API key grants full server-side access to your account. Never commit it to source control, expose it in browser code, or paste it into public forums. The key is shown once at generation — store it in a secrets manager. If it leaks, rotate it immediately from the dashboard.

Confirm a mobile identity with cURL

From your backend, run the request below. Replace the credentials and the mobileNumber. In a real integration, encryptedMobileNumber and operatorId come from the Authmatech SDK after the silent check — see How silent verification works.

Read the response

A successful request returns HTTP 200 OK. Authmatech wraps every response in a consistent envelope: a success flag, a messages array, and a data payload.
data.validNumber is the verdict: true means the customer controls the number they presented. Add ?maskMobile=true to also receive a masked copy of the confirmed number (e.g. ********67).If something is wrong, success is false and the messages array explains why.

Add intelligence to the decision

Once a number is verified, enrich the decision using the same session:

Trust score

Turn the signals into a single 0–100 trust score with a recommendation.

Shield assessment
