Obtaining and Converting a Security CertificateYou are now ready to perform the last setup step to enable you to use the API obtaining and convert- ing the security certificate. As mentioned previously, because the PayPal API deals with monetary trans- actions, you must use a higher level of security than you do with many other Web APIs discussed in thisbook. To obtain a certificate, log into PayPal Sandbox with your test business (seller) account. Click on the Profiletab, and then click the API Access link. Then, click the API Certificate Request link. Fill in the informationrequested to set up a certificate, and then click the Generate Certificate button. Click the Download buttonto download the text file that contains the certificate. Save the text file to a location on your hard drivewhere you can find it later. As another option, an e-mail is also sent that contains a link for downloading your certificate. Again, forthe test Sandbox environment, the e-mail is placed in your online inbox as opposed to being sent to youractual e-mail address. 156Chapter
