Setting up Paypal Express to go Live


Recommended Posts

Hi, I am seriously having a dumb.


How do you set up Paypal Express to be live?


The Paypal Express module asks for


API Username

The username to use for the PayPal API service



API Password

The password to use for the PayPal API service



API Signature

The signature to use for the PayPal API service



I've gone to the Paypal Developer site and made a new app under 'My Apps' but it only provides this under 'REST API Credentials':




Client ID:











Obviously I've changed everyting there to an x. Also now the formatting of this post has gone mad.





The PayPal Express Checkout credentials are not set up correctly for live production use.

array(9) {


string(20) "2014-05-05T11:06:04Z"


string(13) "121f1410a2d26"


string(7) "Failure"


string(4) "60.0"


string(8) "10850615"


string(5) "10002"


string(14) "Security error"


string(28) "Security header is not valid"


string(5) "Error"



Is there a guide somewhere? Obviously a lot of people have managed to do this easily because I couldn't find any topics on it in the forums :) so yes I am having a dumb.

Oh thanks loads. I don't know why I couldn't find it, I guess I figured it wasn't there.


If anyone has this problem again it's currently located on the main Paypal account site under


My Account -> Profile -> My Selling Tools -> API Acess
