      <h1>Transaction Expired</h1>
      <p>The STK Push transaction exceeded the allowable processing time before the user responded.</p>

      <div class="section-label">Likely Causes</div>
      <ul>
        <li>User did not respond to the STK prompt before it timed out (typically 1–3 minutes depending on phone model)</li>
        <li>User&#39;s phone was slow to display the prompt due to network lag</li>
      </ul>

      <div class="section-label">Fix</div>
      <p class="fix-text">Inform the user their payment request expired and offer them a button to initiate a fresh STK push. Implement a polling loop using the STK Push Query API (stkpushquery endpoint) to catch this state proactively before relying solely on the callback.</p>
      <div class="section-label">Notes</div>
      <p class="notes-text">Different from error 1037 — 1037 means the prompt never reached the phone. 1019 means the prompt arrived but the user did not act on it in time.</p>
