Paypal WPP configuration Error 10501

I'm getting this with the "Live" account credentials so I dont think it's sandbox related.

Overridden just means that you've updated the default values of the module. This is normal (you've put in your own settings). As for the original issue, can you post your request log as well?

I'm having the same issue as well. Latest install of Drupal and Commerce PayPal (on WAMP server, localhost). Seems pretty straight forward and have all the API keys correctly input. Is this a PayPal issue or a Drupal issue? Was looking at PayPal error codes, but they are not much help.

Hey @mlaw,
The problem is with your local dev server configuration. Basically the ip_address() function cannot determine your IP and is setting "::1" as your ip. PayPal is rejecting this because it is not a valid IP.

Request Problem:
[IPADDRESS] => ::1
Should Be:
[IPADDRESS] => 127.0.0.1

see http://api.drupal.org/api/drupal/includes!bootstrap.inc/function/ip_addr...

Thanks for the quick reply. I changed over to 127.0.0.1 and still got the same error 10501. At this point, I'm very puzzled.

Well you got a different error response at least. I'm setting this back to active and will try to reproduce again (haven't been able to yet).

This error appears to be caused by Direct Pay not being enabled on the PayPal account and is not caused by a misconfiguration with Commerce PayPal.

https://www.x.com/developers/paypal/forums/paypal-sandbox/transaction-ca...

Thanks for all the helpful info. I'll look into this further and post up my results.

I'm getting this error using Live (not sandbox). I am using Advanced (not Pro).

I enabled Express Checkout in the API Access settings in PayPal and copied the API username, password, and signature to the rule in Drupal Commerce.

Any other thoughts?

This is how I resolved my Error 10501 issue. Thanks to andyg5000 for the guidance.

So, to get a properly functioning Sandbox PayPal Web Payment Pro (WPP) account do this:

1. Register for an account at https://developer.paypal.com/
2. Create a preconfigured U.S. seller test account with the option "Seller (Use to represent yourself as the merchant)" (do not choose the option "PayPal Payments Pro")
3. Go to https://ppmts.custhelp.com/app/home and click Contact Technical Support. Submit a ticket that says you are developing a new site and request that they manually enable WPP for your sandbox account. This is also known as "manually accepting the billing agreement". Provide them with your U.S. seller test account (usually looks like name_1344533052_per@devsite.com).
4. Wait for response (I was approved in a few hours)
5. Enter the proper API username, API password, and API signature into your Commerce PayPal payment configuration. Turn on API logging to see pass/fail status.
6. Test away!

I have testes my configuration with sandbox and is working fine but when I switch to my Live configurations I get the same Error:

Any ideas?

I can confirm this is happening on my live site as well. Also I have no idea where the WPP is getting the $45.00 amount from as the actual sale account is $795.00

Sandbox returns a different error but either way it just cannot successfully accept a credit card payment.

Have you contacted PayPal support yet?

This error is because you probably haven't "upgraded" your sandbox to "Pro". Go to your developer sandbox profile, then click upgrade.

FYI, to follow up on #16 because it's easy to miss:

1. Log on to developer.paypal.com
2. Click the Accounts Link on the left
3. Create a new account if you haven't already done so
4. Copy your facilitator account if you haven't already done so using the blue icons on the far right of the table
5. For you xxx-facilitator-1 account, click Profile
6. Under account type, click "Upgrade to Pro"

Note you can also grab your API credentials for the account by clicking the Profile link, then the "API Credentials" tab.

@webdrips, thank you very much for distilling that down!

Hi All,

I check this thread comment, from these mostly related to facing 10501 response error.

If response not done success and return with some error code then please check paypal response column 'L_ERRORCODE0'. If this response field return 10501 that means you need to check your configuration settings.

Please refer for more paypal error code use paypal site (https://developer.paypal.com/docs/classic/api/errorcodes/).

@Kristina Katalinic : You need to check your all configure variable values because from paypal first response error say that there is some configuration issue ([L_ERRORCODE0] => 10501) so once check and set proper all configuration values.

For the paypal second response is throw 'The amount to be charged is zero', This is because paypal not support zero or less then zero amount transaction but in you case amount is -700.00 USD. See https://developer.paypal.com/webapps/developer/docs/classic/express-chec...

Please feel free to contact for more about paypal module related issue/doubt.

Thanks!

Hi

An existing site (live for 4 months) uses Paypal WPS but non-UK EU customers need to have a paypal acct to pay by Credit/Debit Card. This is a problem, Paypal advise Paypal Business Pro is the way to go.

I am trying to set up a sandbox for testing and I am also getting the same 10501 error. Paypal Tech Support state this is an error with my paypal sandbox "seller" account not being properly updated to act as a test account for Paypal Business Pro. They are endeavouring to fix this.

This is clearly at odds with #19 but in keeping with #12 and #17

The messages I am receiving and sending are:

Which are similar to the other responses received.

Also I am somewhat confused by the fact that the Paypal WPP submodule collects credit card details onsite, this means the site will need an SSL. My colleague tells me that when she set it up it collected credit card details offsite not onsite.

Any thoughts? Any suggestions? Do I need an SSL?

As an update, Paypal Tech Support suggest it is an issue with malformed Paypal Developer sandbox accounts upgraded to Business Pro being malformed. As yet (over 2 months) there is no known solution or workaround.

It would be interesting to know if anyone has upgraded their account recently and not received error 10501.

Regards

Tim

I was also receiving the PayPal WPP response: ... [L_ERRORCODE0] => 10501

This is how I got past it:
1. Create an account at @ https://developer.paypal.com/
2. Under "Sandbox Accounts", click "Create Account", select Type: "Merchant", fill out etc.
3. Under this new account select "Profile", Under "Account type" click "Upgrade to Pro"

If you've been testing other payment methods on a test site, be sure you clear out your payment transaction tables before you try to use PayPal. If you have a test order that's only partway through checkout and can't finish, check to see if the order has old payment transactions. Delete each payment transaction for that order and then try to run the order again.

I got the 10501 error, and a couple of other errors (setting the transaction to $0.00) when I did orders on a test site that still had old payment transaction tests for Example Payment.
