Working with the Paypal API, yes i've checked my config files, yes i've checked username and password.... i'm outa ideas. I'm using the ExpressCheckout API downloaded from and everytime i try call the setExpressCheckout method i get the following error:
NSS: client certificate not found (nickname not specified)
I know it's something to do with an SSL error, how do i go about solving the problem?
On August 3 and August 5 PayPal renewed the SSL certificates for the following API endpoints:
api.paypal.com
api-3t.paypal.com
api-aa.paypal.com
api-aa-3t.paypal.com
If you need to import the new PayPal SSL certificates into your application or system keystore/truststore you can download them from https://ppmts.custhelp.com/app/answers/detail/a_id/920/. If you don't typically import the PayPal SSL certificates into your keystore/truststore, no action is required on your part.
For Sandbox please use this link: https://ppmts.custhelp.com/app/answers/detail/a_id/924 to Download the new SSL Certificate.
Check the paypal's server domain you send request to.
It should be api.paypal.com for certificate based authorization and api-3t.paypal.com for signature based authorization.

I'm trying to connect to the PayPal REST API. This is a Nim program that uses httpclient, but there's nothing specific to Nim since this is just a REST API.
The error I get is:
Error: unhandled exception: error:1416F086:SSL routines:tls_process_server_certificate:certificate verify failed [SslError]
I'm using OpenSSL 1.1.1m on Windows 10.
certificate verify failed
Your environment is not able to verify the SSL/TLS certificate currently used by paypal.com servers.
Update your root certificate authority bundle that's used to trust the signers of TLS certificates; you can download a current one here.
If you don't know where to put it, try openssl version -d
I am setting up a webhook URL for Uber API integration. It is mandatory to use 'https'. For testing i am using a self-signed certificate but the callbacks from uber server are not hitting my endpoint. Do i need to get a real certificate just for testing?
We require a valid ssl certificate in order to receive a webhook. The great news is you can easily setup an ssl certificate for free with letsenrypt. Find out more at https://letsencrypt.org/getting-started/.

I am currently trying to integrate paypal checkout with our online store. We are testing against Sandbox. Everything but the IPN (Instant payment notification) works.
We read a lot about paypal changing their security model so we tried to follow their guide but we are still getting an error:
The SSL certificate for the host could not be verified
the error we get on IPN is:
The SSL certificate for the host could not be verified
Now, we are using a G2 cert from GoDaddy (supports sha256). Not sure if this has anything to do with it or not.
Any help would be appreciated.
I am running out of ideas. We already installed the G5 root cert from Verisign, the site runs in SSL via G2 GoDaddy cert.
Thanks,
Moz
Are you using cURL to get the VERIFIED response?
If yes then contact GoDaddy and get the version number of SSL you have.
cURL by default uses SSLv3.
I had a similar issue, solved it by adding this
curl_setopt($ch, CURLOPT_SSLVERSION, 2);
to my cURL headers.
As per the paypal security upgrade on Jan 17th 2016 they are saying that the server needs to be installed with a ssl server with ssl of algorithm SHA-256 and the certificate needs to verify with a G5 ROOT certificate. But my doubt here previusly i can test the paypal sandbox payment in my localhost(a server without https) and it was worked perfectly. But as per the new upgrade from the paypal team is there any option to check the api service in sandbox in a http server(may be on localhost). When i try this i got a handshake_failure exception.
This was my mistake and finally i understood that ssl not needed. When i have update the paypal sdk jar to 1.4 the issue cleared.
In order to secure my Rest Services, I have enabled SSL in IIS and Created a Self-Signed Certificate and assigned it to the HTTPS binding in IIS. I exported the same as pfx file and added the same in IE also but when I try to access the Services, I get the following error on Windows 7, Enterprise edition
HTTP Error 403.7 - Forbidden
The page you are attempting to access requires your browser to have a Secure Sockets Layer (SSL) client certificate that the Web server recognizes.
And on Windows Server 2003, this is
HTTP Error 403.7 - Forbidden: SSL client certificate is required.
Internet Information Services (IIS)
I am not sure what shall I do except adding the certificate in IE under “Personal” and “Trusted Root Certification Authorities”? Could you please suggest me some step, in order to make this work.
Note: I have tried with “Self-Signed Certificates” as well as with Certificates generated from Microsoft “Certificate Services” also.
Any help is greatly appreciated.
SSL is used to verify the identity of the server, not the identity of the client. The error suggests (http://support.microsoft.com/kb/199215, "This is used for authenticating you as a valid user of the resource. ") the server wants to identify the client. Which of the two are you trying to do?
Edit: SSL requires the public part of the SSL certificate to be available to the client. Adding it to the trusted root certificates seems to me to be the only way to make the public part of a self-signed certificate available to the browser.
