Prestashop paypal error

Prestashop paypal module

This post introduces a serie of Prestashop tutorials. Because you need various type of addons to keep your Prestashop online store running, we will not talk not about Easy Retail Manager but also about other related topics we think could help.

Paypal is a worldwide payment gate allowing both electronic payment and money transfer. It is a good alternative to traditional paper methods such as checks and does not require a subscription to start. Paypal is now probably the most famous payment gate in the world.

Prestashop comes with a free Paypal plug-in. Last month I was setting up a Prestashop web store to one of my customer. When I came to the payment gate configuration and test. I kept getting this message at the end of checkout just before payment. I have an ssl cert but can’t understand why this kept coming up. I have spent  few hours trying to work it out so far and it was driving me mad.

PayPal response:
TIMESTAMP -> 2013-06-25T19:52:02Z
L_ERRORCODE0 -> 10002
L_SHORTMESSAGE0 -> Security error
L_LONGMESSAGE0 -> Security header is not valid

Well It has a link with my module configuration. In most cases, this error is caused by human mistakes. This error indicates that something goes wrong with your Paypal account information(API user/signature) to authenticate you to communicate with Paypal server. So the solution is pretty much simple. In the one hand side, make sure you have input correct information.  Then go to the Settings tab in the PayPal module page. Make sure that the first line that says: Sandbox mode (tests): is set to “Inactive” .  I had mine set to “Active” […]

There will always be people who are happy to keep things at a minimal level but if your business is successful, it is inevitable that demand that will rose and more and more people will flock towards your products or services. This is where online retailers have a decision to make. Do they want to keep ticking along at the same level or do they decide to scale upwards and offer improved services and more options for their customers?

If it is the latter, help is definitely at hand for any online retailer to make the move upwards. It is important to be able to have the right system in place that will allow upward growth. This is where many online retailers decide to look at Prestashop as a way of providing a reliable online outlet for their business.

It is an excellent service for what it provides and of course having no cost but in the business world, customers won’t accept poor quality service just because you are running a free software service as your back and front-end of the business.

Prestashop bulk price update for sales season

Prestashop bulk price update for sales

Easy Retail Manager is suitable for any business. Here is an example of a success story with EZRM. This case study shows how Easy Retail Manager helped our customer to prepare his shop for the summer sale in France.

Thomas owns an Italian suite shop. He runs his business online from his house. He sells shoes, trousers, socks, shirts and suites for men. He has been using Prestashop since 2 years now. A local service provider (basically a web developer) helped him to migrate his web store to the latest version Prestashop

While maintaining his Prestashop store, Thomas wanted to prepare his web store for the Paris Summer sales 2013 where he allowed 20% off all products. He may also need to increase the prices right after the sales season or maybe due to an increase in supplies. This activities could have been tedious and a time consuming process if Thomas has a handful of products. Since he has thousands, this seems downright impossible.

Thomas was locking for a module to reflect the new prices the day before the sales started. Since Prestashop 1.5 is a brand new version only few modules are available. Fortunately, Thomas contacted the Easy Retail Manager team. We advised Thomas to buy the bundle catalogue management for the time being. We showed him how he could decrease/increase the product prices in only few seconds. Thomas used Easy Retail Manager for Prestashop to perform his catalogue update. This removed him the hassle of contacting a contractor.

Easy Retail Manager Is Suitable For Any Business Size

When thinking about the best range of products and software developments to drive your business forward, you need to think about your own business first. It is all very good looking at the biggest firms in the world or the biggest companies in your industry but their working life is likely to be massively different to you. A company that has a strong global presence is going to face different pressures than an emerging industry that you currently operate from home so you shouldn’t always look at the top before you make your next move.

Knowing your own business needs and how you want to develop your business is one of the most important aspects for a firm before they make any buying decision. You should always ensure that you take the time and effort to weigh up your budget constraints compared to what you want to provide to the customer. This is a far better gauge of what you should be buying as opposed to just looking at what the best seller in the industry is. The thing is though, there is a product that is great for online retailers of all sizes and you should be checking out the Easy Retail Manager range of apps and services.
