Paypal Transactions fail with Client API's

Paypal Transactions fail with Client API's

Everything works beautifully within sandbox. When I switch the server behaviors in chekcout.php, pp_confirm.php and confirm.php to point to client API's, the transaction (Express Chekout) fails. Added the full request and response to pp_checkout_failure.php and obtained the full dump

Part of the error message (since the full one contains sensitive info) Posted error log on private ticket.
Security header is not valid</LongMessage><ErrorCode xsi:type="xs:token">10002</ErrorCode>

Is this a client API configuration problem with Paypal ??

yes, the error "Security header is not valid" means that the API credentials being used are not being excepted.

for express checkout, there are 3 server behaviors that need to be changed:
On the checkout.php page:
1)"Authentication For PayPal Express checkout"

On the pp_confirm.php page
2) "Get Payer Profile from PayPal Express Checkout"

3) "Process Transaction with PayPal Express checkout"


all 3 of these must be changed to use the Live API credentials, and in all three, you need to turn the sandbox off.

Hi Jason:

I modified the server behavior to turn off sandbox, but in the "Process Transaction with Paypal Express Checkout", even though I turn off use of sandbox, I see the code below has not changed.

$nextIndex = count($WA_PP_ECO_Do_optional[0]);
$WA_PP_ECO_Do_optional[0][$nextIndex] = "TaxTotal";
$WA_PP_ECO_Do_optional[1][$nextIndex] = "".$eCart1->GetTax() ."";
$nextIndex = count($WA_PP_ECO_Do_optional[0]);
$WA_PP_ECO_Do_optional[0][$nextIndex] = "UseSandbox";
$WA_PP_ECO_Do_optional[1][$nextIndex] = "true";
$nextIndex = count($WA_PP_ECO_Do_optional[0]);
$WA_PP_ECO_Do_optional[0][$nextIndex] = "UseSandbox";
$WA_PP_ECO_Do_optional[1][$nextIndex] = "true";

Should I edit the code manually on these lines ? change "true" to "false"

If so where else should these be changed ?

IN DIRECT PAY (confirm.php) I edit the server behavior "Local Checkout"

$nextIndex = count($PP_DirectPayment_required[0]);
$PP_DirectPayment_required[0][$nextIndex] = "UseSandbox";
$PP_DirectPayment_required[1][$nextIndex] = "false";

IN checkout.php server Behavior "Authentication for Paypal Express Checkout" took the switch off
for Sandbox and I do not see that variable in the code.


Thanks

Changed the server behaviors and turned off sandbox as detailed above.

Express Checkout does not go to confirm page, directly goes to pp_checkout_failure.php

I dumped the full request and response and have posted on private thread also zipped the confirm.php, checkout.php and the pp_confirm.php files. PLease take a look. I would like to resolve this as soon as possible. Private Ticket number 117052

Is it possible that the Client has not enabled Payment Pro and hence this is happening ?

API credentials had a space after username, When I fixed that pp express checkout reaches the paypal login page. So that one seems to work.

Just updating thread.
