PayPal Express Checkout - Sandbox testing

I'm not having any success with this, so in the aim of converting this into documentation, here we go... please correct my assumptions.

Login to Developer site using the credentials of the Paypal account that you will be using for your shop.
Create two sandbox accounts (may be auto-created):
1) Business type, the credentials of which will be used in ZC module configuration.
2) Personal type, which will be the test/buyer account.

I have a vanilla 157 site on a separate server from my production site.

Zen Cart: Setup Paypal Express Checkout

from the sandbox Business account-> API Credentials
Username:
dksdcssblah_blah_api1.business.example.com
Password:
U29JZ4ZR4YCZ6XZY
Signature:
Ab3Mh4rtqN4ZrF9AO1pTQVgoi7paAgBltIHlUCnXrd8FfNpQ96iVtXYZ

PayPal Merchant ID from Profile->Account ID
ZBC9HXN3RBXYZ

After entering these details and attempting a transaction, whether using InContext or old, I get bounced back to the 2/3 checkout payment page with an error:

At no point am I asked for PayPal login credentials.
Neither do I see anywhere to "tell" PayPal the address/domain of this test site.

From the site, the ipcheck is ok, the curtester is ok apart from tlstest.paypal.com being permanently offline.
From Paypal developer, the IPN simulator reports that it connects.

I see in the log there is a timeout error...but what to do about it?

Hi Torvista,

I'm not sure how much address data PayPal actually matches, the one obvious thing to me is your test account zipcode is wrong. Californian zipcodes start with 9 so it possibly is failing at that point.

Regards raptar

PayPal never offers a login, so should not be trying to match anything at this point.

yeah i think that's wrong, and you should enter a valid US shipping address.

Code:

---

gnome: # grepp _TEXT_ADDR_ERROR
modules/payment/paypaldp.php:1882:          if ($response['L_ERRORCODE0'] == 10736) $errorText = MODULE_PAYMENT_PAYPALDP_TEXT_ADDR_ERROR;
modules/payment/paypalwpp.php:2913:          if ($response['L_ERRORCODE0'] == 10736) $errorText = MODULE_PAYMENT_PAYPALWPP_TEXT_ADDR_ERROR;
languages/english/modules/payment/paypaldp.php:45:  define('MODULE_PAYMENT_PAYPALDP_TEXT_ADDR_ERROR', 'The address information you entered does not appear to be valid or cannot be matched. Please select or add a different address and try again.');
languages/english/modules/payment/paypalwpp.php:47:  define('MODULE_PAYMENT_PAYPALWPP_TEXT_ADDR_ERROR', 'The address information you entered does not appear to be valid or cannot be matched. Please select or add a different address and try again.');

---

when i searched the ZC code for your error, it clearly looks like there is a $response that indicates the error. without digging further, it seems unlikely that the $response var is not something that came back from paypal.

in addition, changing the shipping address to a valid shipping address is such an easy solution to test out as opposed to sticking to your guns about the paypal login.

best.

I took a hammer to it and set
[ADDROVERRIDE] = 0
in the module code, to see what hapened...and the login came up and the order proceeded, producing multiple orders and a white page of death on confirmation,
with
PHP Fatal error: Uncaught Error: Call to undefined method paypalwpp::payment_status() in /home/...../zencart-157/includes/modules/payment/paypalwpp.php:498

Further investigation leads me to conclude this payment process does not work as I expected....so need to waste more time on this....
