Title: Paypal Error
Post by: mthings on December 08, 2015, 11:31:34 AM

I have been trying to use the Paypal pro extension but after putting in the api username, password and signature, testing gives me this error
PayPal Error: Security header is not valid. Please check your API Credentials and try again. Also please note that Test mode is ON! which also appears on my checkout as Security header is not valid when i try to confirm an order on my website.

I need help with how to rectify it. Thanks

Hello.

In PayPal two APIs for Test and for Live. Make sure you set TEST: On and use Test APIs credentials.

Thanks for the information. However, when go Paypal they have 2 options under Set up API credentials.

Option 1 is Grant API permission and Option 2 is to view the API Signature. The option 2 in this case comes up with only one set of details and there are no other options to choose from live and test. Could you please help furthur
