Using the Permissions Service

Generating Signatures for the Authentication Header

Signature=tLWUfZU9Np/7qgPqWF1LMIWjY1s=

Timestamp=1285744515

Use the values to construct the header as follows:

X-PAYPAL-AUTHORIZATION=timestamp=12857 44515,

token=5wZptMaHXQfihLKZFscuGjeKOPqQrlfHFPqRc1QlItX3vYi6,

signature=tL WUfZU9Np/7qgPqWF1L MIWjY1s=

Java Example

The PayPal Java SDK provides a method for creating the X-PAYPAL-AUTHORIZATION

header. See the getAuthHeader method in the OauthSignature.java file of the

com.paypal.sdk.util package in paypal_base.jar.

import java.util.Iterator;

import java.util.Map;

import com.paypal.sdk.util.OAuthSignature;

import com.paypal.sdk.util.OAuthSignature.HTTPMethod;

public class TestOauthSignature {

private static String apiUserName = "..._biz_api1.gmail.com";

private static String apiPassword = "1255077037";

private static String accessToken = "2WhQDDM4...";

private static String tokenSecret = "j0YhbTgcy.K5VjpQa7Ru8oM...";

private static HTTPMethod httpMethod = OAuthSignature.HTTPMethod.POST;

private static String scriptURI = "https://api.sandbox.paypal.com/nvp";

private static Map queryParams = null;

public static void main(String[] args) {

try{

Map map = OAuthSignature.getAuthHeader(apiUserName, apiPassword,

accessToken, tokenSecret, httpMethod, scriptURI, queryParams);

// Display Signature and Timestamp to console.

Iterator itr = map.entrySet().iterator();

while(itr.hasNext()){

Map.Entry entry = (Map.Entry)itr.next();

System.out.println(entry.getKey() + ": " + entry.getValue());

}

}catch (Exception e) {

// handle exception

}
