title: How to get public key in Google pay integration with Direct token specification approach
body: <p>I am trying to integrate google pay in my android app. I want to integrate google pay without any payment gateway in between (means DIRECT approach rather than PAYMENT_GATWAY token specification). I found DIRECT method integration code on official site. In that google asks for protocolVersion and publicKey as parameter and below i found that i can get my public key in my Google Pay Developer Profile. I searched for Google Pay Developer account but unable to found public key Anyone can help me to get public key for google pay DIRECT integration? </p>
  
  <pre><code>private static JSONObject getTokenizationSpecification() {
    JSONObject tokenizationSpecification = new JSONObject();
    tokenizationSpecification.put("type", "DIRECT");
    tokenizationSpecification.put(
        "parameters",
        new JSONObject()
            .put("protocolVersion", "ECv2")
            .put("publicKey", "replace with public_key"));
  
    return tokenizationSpecification;
  }
  </code></pre>
