TLS & Security update & Deadline

By · 26 September, 2016

Security is at the heart of what we do at Judopay and as a result we ensure we’re always staying on top of the latest industry-wide security updates & changes, like PCI.

What is happening?

As you may be aware by now the PCI Security Council released the PCI-DSS 3.1. The main change related to the deprecating of TLS 1.0 & SSL 3.0 as recognised secure protocols. As stated in our previous emails this means that there are a few mandatory updates you need to be aware of.

From October 20th any connection (App/Web/API) to Judopay that is not using the following will not be able to process live transactions.

What do I need to do?

TLS 1.1+
Please ensure that you are using TLS 1.1 onward as a cryptographic protocol to effectively communicate with Judopay’s systems with both sandbox and live environments.

Please ensure that you have implemented the SHA-256 certificate to ensure the communication between both sides are well protected against cryptographic attacks.

Web payments & Web payments API
If you’re using our Web payments solution or have integrated using our Web payments API make sure you’re using the latest major version of our API (5.0+) and your are pointing to the correct endpoint ( Both settings are listed in the transaction header declaration before the payment request.

If you’re using any of our SDKs please ensure that you are using:
• iOS SDK (Kit ObjC and Kit Swift) version 6.0 or newer
• Android version 5 onward
• Xamarin version 2.3.0 or later
• .NET SDK 1.1.113 or newer

These SDKs can be found on Github.

If you would like to test these changes our sandbox environment is currently updated with the above changes.

If you require any support with this migration please contact

State of the in-app payment experience

By · 13 June, 2016


‘Aaarghh – why are they asking me for all this, all I want is to pay!’

I am often heard growling something along those lines (swearing omitted), when I try to complete a payment from my phone.

As the UX lead at judo, when faced with poor checkout experiences – that, I some years ago might have accepted as the painful way of things – now invoke similar reactions in me as when my older relatives are having ‘computer problems’, blood pressure included. Read more

From .NET to iOS — what I learnt during my break through to the ‘other’ side

By · 23 May, 2016

For the best part of the past ten years, I’ve been a software developer, with the majority of that time building .NET applications. Microsoft has a platform that enables languages such as C# to be incredibly powerful, constantly evolving, and expressive, yet easy to read and follow. Technologies such as ASP.NET MVC, WebAPI and EntityFramework remove much of the complexity from the developer, allowing them to concentrate on their primary tasks — building and releasing software.

Recently, I was given the opportunity to cross-train, learn and contribute to judo’s iOS native SDKs. Given the above, I surprised myself with how quickly I jumped at the chance. I’ve been working with the SDK team for just over a month now, below are some initial thoughts from my jump to the ‘other’ side.

Xamarin Evolve 2016 re-cap — What we saw and learnt

By · 12 May, 2016

Judo participated at Xamarin Evolve this year in Orlando. Since Microsoft’s acquisition of Xamarin, this space has gotten hotter so we decided to be in the midst of the action and leverage the hard work we have done thus far on this platform. Below I interview Janice and Luke, who represented judo at Evolve, to capture their thoughts from the event.

What did you think of the Keynote?

Luke: I really enjoyed it, I think it just shows the strength of the platform that, even with Build a month earlier lifting the veil on a lot of .NET news and Xamarin’s big bombshell for the year, they had a lot to talk about. I liked Miguel’s presentation better but that’s just cause he got to hand out all the developer goodies.

Janice: I thought it was a really well structured delivered keynote, it set the tone for the rest of the conference, strengthened the case for cross-platform native development, and addressed the implications of the recent acquisition head on. The whole theme of end-to-end DevOps lifecycle management gave context and framed the new features announcement nicely. Also, the slides were beautiful, big kudos to their design team, I was mesmerised by the color palette!

Android Pay set to launch in the UK

By · 23 March, 2016



After launching in the US last year, Android Pay™ is finally coming to the UK. It has enormous potential to make 2016 a very significant year for mobile payments. Android has a 51.9 %* market share in the UK which means millions of Android users will now be able to pay for things quickly and securely with just a single tap, whether in-store or in-app.

Upgrading to our new iOS Objective-C SDK (4.7.2)

By · 01 February, 2016

We have come a long way from the 4.1 iOS Objective-C SDK. Since the release, we have introduced our new collection of Swift SDKs,  judoSwift, which simplified the communications with judo’s REST API, and paved the way for the feature rich judoKit. Our kit contains out-of-the-box functionalities like Address Verification System (AVS), 3D Secure, and other input verifications necessary for submitting card information for payments and other transactions. Together with our mobile-specific fraud prevention judoShield module, we provide the perfect basis that makes accepting transactions easier, simpler, and more secure.

In our pursuit to make payments in apps even more secure, and due to changes in PCI’s security standards, we are phasing out some older versions of our tech. This means you might need to upgrade to our latest SDKs by the 20th October 2016.

This guide will walk you through the steps needed to upgrade your app to the latest SDK.

Upgrading to our new Android SDK (5.1)

By · 28 January, 2016

In version 5.1 of our Android SDK, we wanted to introduce lots of new features, focus on improving the quality of the codebase, and make customizing the SDK to match your app’s brand easier. With this in mind, it made sense to completely rewrite the SDK from the ground up.

If you’re using an older version of the Android SDK (pre 5.1), you will need to complete an upgrade to this version by 20th October 2016 due to PCI Compliance changes that were introduced (PCI DSS 3.1).

To make the process of upgrading to version 5.1 as smooth as possible, let’s walk through the main steps required to get your app updated.

PCI DSS 3.1: early TLS’s days are numbered

By · 21 January, 2016

Security is at the heart of what we do here at judo, and to ensure that our platform and services are adhering to the latest security standards laid out by the PCI council (PCI DSS 3.1), we have made some updates to our API and SDKs.

These updates mean that we will be ending support for TLS 1.0 and below on 20th October 2016. After that date, any API requests or dashboard sessions will need to use either TLS 1.1 or TLS 1.2. (However, while not being immediately phased out, TLS 1.1’s days are numbered as well, so we would highly recommend an upgrade to TLS 1.2.)

What I learned writing my first SDK

By · 19 January, 2016

This summer, I came across an opportunity to write my first SDK, so I leapt at it. As developers, there is something very appealing about writing software for use by other developers. It might be because of the sense of solidarity that you’ve made life easier for sisters/brothers in code, or the thrill of a backseat driver finally getting a chance at the wheel. That is until the realisation that the demographic you’re serving will also be the best equipped to critique your output, this is especially true when producing an open source repository.

So below are some lessons (some key, some trivial) that I learned while coding judo’s Xamarin SDK.

Get ready for the holidays – start with a bountiful mobile Black Friday

By · 04 November, 2015

Black Friday

As an app developer or retailer – you have the sweetest opportunity to engage, and sell – to your loyal customer base in the coming months. Furthermore, this is the time of year to attract and retain new customers with great offers during a time of commercial frenzy.

Experts have predicted that the frenzy of Black Friday can ‘lead to the first £1bn online shopping day in the UK’. A recent survey also suggested that many shoppers have been put off by the frantic in-store shopping experience, and hence ‘only 38 per cent of Britons plan to hit the shops on Black Friday as opposed to 44 per cent last year’.

To help you get ready for the impending holiday season, we have pulled together some tips to make sure your mobile app is prepared when shoppers arrive looking for holiday deals.

Don’t forget the unicorns, work with them instead.

By · 21 October, 2015

Work with unicorns

 Last week, James Quinn, the Group Business Editor of Telegraph Media Group, wrote that Domino’s Pizza is ‘far more valuable a digital company than any tech unicorn’ (read the full piece here). It is a good opinion piece, and we agree that Domino’s has seen major success in their investment in digital and mobile channels (we like what they did with their app, we even wrote about it here). However, it is rather concerning that one of our country’s leading business voices doesn’t seem to buy into the future of London: ‘so-called unicorn tech companies’.

The elephant in the retail room: going native vs keeping legacy

By · 15 October, 2015

Mobile now accounts for more than a quarter of all e-commerce transactions globally, and that number is increasing rapidly as our shopping behaviour continues to shift towards mobile first. The speed of commerce growth on mobile channels is now 3 times faster than on traditional e-commerce channels. UK commuters are already spending £9.3bn a year on the supercomputers in their pockets. We are increasingly trained to expect the purchasing experience on mobile to not only be easy but also fast. Which is why an overwhelming 69% of consumers would abandon a purchase if the checkout process within an app or website is not optimised for mobile devices.

Why is it then, that most of the top 100 retailers in the UK are still failing to offer customers a quick and seamless native mobile checkout experience?
