I have been trying to configure Paypal for my website, however both Paypal 1.2.1 & 3.5.5 didn't work after I input everything on the API settings, please help!

Using PrestaShop 1.5.4.1 in USA, and it is a fresh installation.

Was trying Paypal 1.2.1 at first since it said for USA & Canada, so which one should i use instead and where can i find it?

Thanks for your quick response!

Since you are in the USA you should try the 1.2.1. . You can download it here, [url="http://addons.prestashop.com/en/payments-gateways-prestashop-modules/8277-paypalusa.html"]http://addons.prestashop.com/en/payments-gateways-prestashop-modules/8277-paypalusa.html[/url]

Make sure to always have a confirmed backup of your database and PrestaShop files and then you should delete the existing PayPal module from your website, and install this version via the back office>Modules>Add new Module.

[b] API Access[/b]

An API (Application Programming Interface) allows PayPal software to communicate with your online store or shopping cart.
[b] Setting up API permissions and credentials[/b]

Choose one of the following options to integrate your PayPal payment solution with your online store or shopping cart.


[b]Option 1 [/b]- Grant API permissions to a third party to use certain PayPal APIs on your behalf.
Choose this option if:[list]
[*]You are using a pre-integrated shopping cart, hosted by a third party
[*]Your website is hosted and managed by a third-party service provider
[/list]
[color=#0000ff][u]Grant API permission[/u][/color]



[b]Option 2 [/b]- Request API credentials to create your own API username and password.
This option applies to:[list]
[*]Custom websites and online stores
[*]Pre-integrated shopping carts running on your own server
[/list]
[color=#0000ff][u]View API Signature[/u][/color]
[b] Accept payments from your online stores before setting up APIs[/b]

[color=#0000ff][u]Enable Express Checkout[/u][/color] to accept payments from your online stores right away. You can set up API permissions or credentials later.
[b] Questions?[/b]

If you're not sure about setting up APIs, ask your shopping cart provider or website developer. [url="https://www.paypal.com/us/cgi-bin/webscr?cmd=xpt/Merchant/popup/APIConceptsAndTerminologyPopup"]Learn more[/url] about PayPal API concepts and terminology.

[b]>>> which option should l use since I tried option 2 but the API signature I input to the configuration didn't work?[/b]
[b]>>> if use option 1 i need the "Third Party Permission Username" yet where do i find this username?[/b]

Hi, which option will you be using, PayPal Express Checkout which uses the standard PayPal API, or will you be using PayPal Pro/PayPal Advance which uses the PayPal PayFlow API.

All of these options are within the PayPal module that you have.

hi Benjamin You said UK also needs a different module but I can only find Europe specific and USA modules...

I updated PayPal in the back office to 3.5.7 and now it doesn't work correctly. I get a the same error message as above.
Which one should I use? For now, I'm just rolling back to the earlier version to try and get it working again.

Thanks
Andrew

I just installed the latest European version for use in UK and appears to be ok (someone please correct me if this is wrong).

However, I had a lot of problems trying to get it to work after the upgrade. I explained how I got around the problem here: http://www.prestashop.com/forums/topic/268385-paypal-problem/page__p__1341848#entry1341848

Hi peoplej.com can you show me the configuration screen that you are talking about, screenshots would help. Usually when you ask for new API credentials from PayPal you will be able to complete the configurations.

I am having the same problem and I don't believe its due to the version, I just installed PrestaShop 1.5.5 and the PayPal 1.2.5 comes with it already.  I am configuring PayPal Advanced and get this error on the Advanced Settings

 

Your PayPal Manager Configuration crendentials are not valid, please double-check their values or contact PayPal.

 

Please help!

i get the same thing when trying to configure paypal advanced. Interestingly though, if I switch to payflow it accepts the credentials. Still tells me i don't have a payment module installed at checkout, but it does accept the credentials.

I tried the same thing yesterday after reading that you need to install both PayPal Advanced and a PayFlow Gateway.  I also reread an email that I would need to wait a day to be approved for the PayPal Advanced and would receive an email when I was but haven't yet received anything.  They said I would get it in 24 hours which was Thursday.  Not impressed with this whole experience.

Hello all, you may need different Credentials for PayPal PayFlow/Advacned and PayPal Standard. 

 

This is only for PayPal USA 1.2.5 for USA, Mexico and Canada. 

 

Please let me know if you are having trouble with this module and report any suspected bugs to the forge at forge.prestashop.com . Let me know of the reports and we will take a look. Thank you!

Hi -

 

I experienced something similar and the Prestashop is not entirely clear on the set up for Paypal Advanced.  After spending upwards of an hour on the phone with the Paypal support folks, here is what I had to do:

 

#1a - in Paypal manager, you have to create a user.  I thought my own name was a user since it seems to be listed that way.  Nope.  Prestashop wants a real user.  So I had to create a user, with my information, and then I was able to login and avoid the error @stevierayhall reported.

 

#1b - then you take that name of the user and insert it the required field in the Prestashop Paypal module and you get a green light.

 

#2 - in the Prestashop Paypal module, you have to uncheck the Paypal Standard.  Prestashop doesn't tell you that but the Paypal folks told me that I couldn't have all the fields filled in for both standard and advanced.  So I asked how I would undo the standard and they said to simply delete all the fields under the standard and hit save. 

 

#3 - about the approval process: Paypal folks told me it would take 48 hours to get approved.  I got a message about 2.5 days after submitting the application which I did live with the tech support folks.  It takes time. 

 

I hope that helps.

 

Brian
