Carl Favre Posted August 18, 2011 Share Posted August 18, 2011 Most of the time when you have the following error L_SHORTMESSAGE0 -> Security error L_LONGMESSAGE0 -> Security header is not valid L_SEVERITYCODE0 -> Error It means that your credentials are incorrect or that you are using sandbox credentials with production mode (or production credentials with sandbox mode). If you are in production, you have to check INACTIVE for SandBox mode (be sure to fill the configuration form with your production credentials and not your sandbox credentials). 1 Link to comment Share on other sites More sharing options...

Fabien Serny Posted September 18, 2011 Share Posted September 18, 2011 If the problem is not coming from the test mode that means your credentials are incorrect. Please copy paste them again, be careful to not add any space. 3 Link to comment Share on other sites More sharing options...

jazzyjen Posted November 27, 2011 Share Posted November 27, 2011 I am getting this message but how do I know if I have sandbox or live credentials? I tried removing the API and creating another but that did not work. Paypal is bleating on about live API endpoints but there is no place to enter them on PS Help please! I am also freaking about world pay so if you can help with that let me know!!! Thanks xxxx Link to comment Share on other sites More sharing options...
Fabien Serny Posted November 28, 2011 Share Posted November 28, 2011 Hi Jen, When you retrieve your credentials from PayPal, it has to be written if it's for sandbox or production. What are you calling live API endpoints exactly ? Link to comment Share on other sites More sharing options...
jazzyjen Posted November 28, 2011 Share Posted November 28, 2011 Ah- it has resolved overnight and now works... who knows?? The paypal vocab and the vocab used within Presta is not the same...

WartoWiedziec Posted November 28, 2011 Share Posted November 28, 2011 Hi Fabien, I'm looking for a new module of PayPal. Currently I have installed version v2.6. I'm looking for, because I have a problem with the normal process of paying. When you select apayment method paypal goes to the next page, but white and at the top of the screenshows the information unintelligible to me. When you search for a solution I decided to find a new module, as an antidote to this problem. Unfortunately I can not find this module. I downloaded it from SVN, compresed with WinRar pack but this solutiondoes not work - that is, dont want to install the module. So finally I'm looking here foradvice from you as a [spam-filter] from PayPal. PS 1.4.4.1 www.plytacmb.pl I would be glad if you can help me with this.

Fabien Serny Posted January 5, 2012 Share Posted January 5, 2012 This error is returned by PayPal when credentials are incorrect (it's not an error generated by PrestaShop). And this error always happen when credentials are incorrect (I never saw any others cases). Are you sure you copy / past it properly (no adding space, take the all signature, etc...) are you sure you have generated production credentials (not sandbox) ?

T-bird Posted August 27, 2012 Share Posted August 27, 2012 (edited) I'm getting this same error but the fix isn't working. I've checked and re-checked the API info half a dozen times, I've even tried manually typing it in but I still get the '10002 Security header is not valid' error on checkout. I've tried it with and without cache enabled and with force compiling on or off. Still no joy. I've uninstalled and re-installed the Paypal module several times but it still doesn't work and I've checked it is not in test mode. The only solution I can find in the forums is a mistake in the API info but that definitely is not it in my case. Any other ideas?

panhead Posted August 28, 2012 Share Posted August 28, 2012 T-bird, I have exactly the same experience as you. I opened a new topic, because I did find out that it will work (with some problems) if you use Opera. So the API settings are correct. Hope this helps.

sixpack Posted October 5, 2012 Share Posted October 5, 2012 I'm having the security issue.

visualnz Posted October 9, 2012 Share Posted October 9, 2012 This seems to be an on going problem with Paypal intergration the thing I find interesting is it is explained as human error? I have 3 subdomains all set up identical and at the same time...one site was no problem at all to set up with Paypal...2nd and 3rd using the same settings and id etc wouldn't work, I got the same reply as everyone here regarding Security Header not valid...I got pissed off trying to fix it and left it over night tested the 2nd site the next day it worked fine ( I had changed nothing ) the 3rd site still won't work nicely with Paypal So to say it is human error is a long stretch it seems to reset or refresh to the correct settings on its own??? At the moment I have 2 out of 3 sites working fine all the sites are set up exactly the same as far as I can tell and I have wasted a lot of time checking they are the same It is a bit odd that 2 out 3 work but not all...when all I had to do was cut and paste the same id 3 times can that be human error ? More likely it is a problem with the code or sand box buttons in Paypal ...but I have run out of idea's that I can control to fix it other than wait and see if it fixes its self like one site did any suggestions... and yes I have read the threads on this subject and tried the fixes Link to comment Share on other sites More sharing options...

PresTeamShop Posted October 30, 2012 Share Posted October 30, 2012 Greetings community, Please note: - It has happened that when you install the new Paypal and set the configuration variable "PAYPAL_API_SIGNATURE" not saved correctly. What we should do is directly to the database table "ps_configuration" and search the name the word "PAYPAL_API_SIGNATURE" and edit the value NULL for its Signature and go! What if it happens to someone! Best regards. Link to comment Share on other sites More sharing options...

It is trying to use paypal api info in real mode when it is in actual test mode, follow... ok, now I go to sand box in order to try to find API info to replace the actual API info... I see nothing that really relates in sandbox... It does appear to work when it is in non-test mode, but I need to be able to test it to make sure, since I can not use my own paypal to test... I do not see the following info in sandbox... API Username API Password API Signature Since I have this in test mode, exactly what and where do I get the info in order to complete a successful paypal test? I also have a google check out question...when I setup my google url, it would not accept it the url as it said I had to use https:// does this mean I need to get SSL?

diffy Posted January 22, 2013 Share Posted January 22, 2013 Good news everyone! I have been trying to get Paypal to work for the last day, and it has been giving me a serious headache. Mostly because I have done EVERYTHING right, yet I still got this dreaded error message. Now I would like to tell others of the solution that I found. It turns out that when you click GET MY PAYPAL API CREDENTIALS from within the Paypal Module, the popup that show up gives the details. But the real problem is that this popup is not showing the ENTIRE API Signature string. I found this out by going logging into Paypal -> My Profile -> Other Alternatives -> My Sales Tools -> API Access -> Show API Signature From here I found that the string had been cut out, and when I pasted this COMPLETE string from the Paypal website, Prestashop's Paypal Module worked perfectly. Cheers all Link to comment Share on other sites More sharing options...
KenSTJ Posted January 24, 2013 Share Posted January 24, 2013 new install of 1.5.3.1 - PP module supplied in zip did not work - generated incorrect security header - out of desperation and lack of support/documentation - updated to new version 3.4.4 and works fine first time.
