Request Authentication Example

To make sure that request is authorized by Connecting Party, all requests must be signed. MAPI works with OAuth 1.0a HMAC-SHA1 signature as it is a well-established and supported in the client libraries.
MAPI supports only the signature part and does not support a full-blown OAuth. Connecting Party control key is used as a secret key.
Below is an example of how to make a signed request in Java with help of scribe library:

import org.scribe.builder.api.DefaultApi10a;
import org.scribe.model.*;
import org.scribe.oauth.OAuth10aServiceImpl;
import org.scribe.oauth.OAuthService;
import org.scribe.services.HMACSha1SignatureService;
import org.scribe.services.SignatureService;
import java.util.Map;

public class App {
    public String doPost(String url, Map<String, String>parameters) {
        OAuthConfig config = new OAuthConfig(apiToken, merchantControlKey, OAuthConstants.OUT_OF_BAND,
                SignatureType.Header, null,null);
        OAuthService service = new OAuth10aServiceImpl(new HmacSha1Mapi(), config);
        OAuthRequest request = new OAuthRequest(Verb.POST,url);
        for (Map.Entry < String,String > entry :parameters.entrySet()){
            request.addBodyParameter(entry.getKey(), entry.getValue());
        } // empty token for 'two-legged'
        Token token = new Token("", "");
        service.signRequest(token, request);
        Response response = request.send();
        return response.getBody();
    }

    private static class HmacSha1Mapi extends DefaultApi10a {
        @Override
        public String getRequestTokenEndpoint() {
            return null; // not used
        }

        @Override
        public String getAccessTokenEndpoint() {
            return null; //not used
        }

        @Override
        public String getAuthorizationUrl(Token requestToken) {
            return null; // not used
        }

        @Override
        public SignatureService getSignatureService() {
            return new HMACSha1SignatureService();
        }
    }
}
