3. 3 Contained REST APIs Common Mistakes Integration Possibilities Mobilizing the Web

4. 4 REST APIs User makes a request to the REST API. User receives JSON response. Related SOAP API is called on the server. A HTTP POST call is all you need. Doesn’t require you to play with WSDL files. Implement with almost any programming language.

5. 5 How to use REST APIs? 1. Get the URL for a specific API. 2. Gather the required parameters. 3. Make a HTTP POST call to the URL. 4. Parse the JSON response. Let’s see! Can this be any simpler ?

6. 6 REST APIs Code Sample <?php <?php$a['registrationID'] = "masnun"; $a['password'] = "******"; $a['sourceMsisdn'] = '8801711******'; $a['destinationMsisdn'] = '8801711******'; $a['smsPort'] = 7424; $a['msgType'] = 4; $a['charge'] = 2.00; $a['chargedParty'] = '8801711******'; $a['contentArea'] = 'gpgp_psms'; $a['msgContent'] = 'Hello GP API!'; $ch = curl_init("http://masnun.com/aloashbei/sms/send"); curl_setopt($ch, CURLOPT_POST, 1); $data = ""; foreach($a as $k => $v) { $data.= "$k=$v&"; } curl_setopt($ch, CURLOPT_POSTFIELDS, $data); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); $result = curl_exec($ch); var_dump($result); ?>

7. <?php 7 Parsing JSON Response <?php$dataObject = json_decode($result); echo $dataObject->SendSMSResponse->status; ?>

8. 8 Detailed Docs on REST APIs For documentation and API specific code samples: http://masnun.com/aloashbei/

9. 9 Common Mistakes While Working with the APIs 1. Not editing the WSDL file. 2. Missing out one or more parameter. 3. Wrong Request Name. 4. Miss-matching parameters. 5. Others. Look into the docs. Use the Wiki or Forums. And how to resolve them?

10. 10 Integrations Python PHP SoapClient REST APIs

11. 11 Integration : PHP <?php$soap = new SoapClient("http://localhost/gp/wsdl/WebService_GP_ADP_BizTalk_LBS_Orchestration.asmx"); $a['registrationID'] = "masnun"; $a['msisdn'] = '8801711******'; $a['password'] = “******"; try { var_dump( $soap->requestLocation( array ("LBSRequest" => $a) ) ); } catch (Exception $e) { var_dump($e->getMessage()); } ?>

12. 12 Integration : Python Python aims to combine "remarkable power with very clear syntax" Wikipedia PyQT Django / Google App Engine GUI Apps Web Apps

13. 13 Python & REST APIs import urllib, json req = { "registrationID":"masnun", "password":“******", "msisdn":"8801711******" } url = "http://masnun.com/aloashbei/location/get" input = urllib.urlopen(url,urllib.urlencode(req)).read() data = json.loads(input) print data['LBSResponse']['Status'] print data['LBSResponse']['Latitude'] print data['LBSResponse']['Longitude']
