There is an interactive wizard that will guide you through the whole setup process:
Yes. This process can be done in four steps:
That depends on the project, but in general, before purchasing a device, make sure that it meets the project requirements. For example, if mobility is an important factor, a device with GPRS should be considered. It's also necessary to ensure that the device is compatible with CloudWalk.
Check out the approved devices list.
Yes, that's perfectly possible, since CloudWalk devices are prepared to handle multiple POSXML applications. If a device was configured to have access to a single application, when the green button is pressed, that application is automatically started. However, if the device have access to multiple applications, when the green button is pressed, a menu listing all of the applications is displayed, so you can choose one of them to start.
The Group management section defines which applications should be accessible to a group. After configuring a group, any amount of logical numbers can be assigned to that group, through the Logical numbers section.
Check out the HTTP integration example.
The default password is 55555.
Yes, check out the password change guide.
Get in touch with your POS terminal supplier and request a reset file, which then can be used to reset the certificate.
Check the following points:
The CloudWalk Manager is a tool used to grant access to devices, register applications, files, logical numbers and groups. It is also through this tool that user management and transactions monitoring is done.
The Cloudwalk service provides a simple, fast and intuitive development environment accessible to anyone using a web browser, it provides the innovative use of real-time collaboration, by which multiple developers can work on the same application simultaneously.

POSXML (acronym for Point Of Sale eXtended Markup Language) is a programming language that is used to create applications for POS terminals.
Normally the programming language used to develop POS terminal applications is C or C++, which requires an in-depth knowledge of both the technical specifications of the machine (Hardware) and the programming language.
The main purpose of POSXML is to simplify the development of applications for POS terminals. It contains a set of instructions and pre-programmed commands, which allow direct interaction with the device, resulting in a large reduction in application development time.
The maximum size of a String is 1024 bytes.
All reserved characters in XML are also reserved in POSXML and should be written in the correct way.
The following symbols on the left should be written as they appear on the right:
< < > > & & ' ' " "
There are more information about the POSXML structure.

Yes, there is a sample bitmap.dat file which you can use as an entry point, but you should check and update the parameters and the type of each bit according to your ISO8583 host specification before downloading it to your devices.
Due to the diversity of all CloudWalk supported devices, to use a custom background image, it is necessary to follow a set of rules in order to achieve the best results for a given device.
|Device model||Bitmap type||Filename||Sample|
|Verifone VX 680, VX 685, VX 820||Color (243 x 276)||walk.bmp||View|
|Verifone Verix 510, VX 520||Monochromatic (119 x 57)||walk.bmp||View|
|Ingenico iWL280||Color (245 x 156)||walk.bmp||View|
|Ingenico iCT250, iWL250, iPP350||Color (288 x 156)||walk.bmp||View|
|Ingenico iCT220||Monochromatic (119 x 57)||walk.bmp||View|
After creating your custom image, follow these steps:
Note: Only bitmap (.bmp) images are supported. Other formats like JPG, GIF and PNG are not supported.
Authorizer is the component responsible to verify and validate the information provided by POS terminals.

The endpoint is configured at application level, through the following steps:
No. An application can be associated to only one endpoint. Note that the modules being used by an application will automatically use that application's endpoint.
However, if you need to communicate with multiple endpoints on the same application, you can follow these steps:
Yes! Check out the API section for more information.
That depends on the device, but in general, Ethernet, GPRS and dialed is supported.
That's quite simple! All you have to do is set the IP to 0.0.0.0. After restarting the device, an IP should be automatically assigned to it.
First you need to check if your GPRS SIM card uses private or public APN. You can get this information with your SIM card provider.
If you have acquired the chip through a telecommunication company such as Lyra Network, it will probably use a private APN, otherwise it should use a public APN. The username and password should also be requested with your SIM card provider.
Brazilian customers can take advantage of some pre-configured providers (CLARO, TIM, OI, VIVO, LYRA, etc), while customers outside of Brazil should pick the option Other operator and manually enter the information.
In general, you can assume that our service is always up. If you are not sure, just check our status page. So assuming that our service is up, communication problems should be related to your POS, your infrastructure or some sort of configuration.
When troubleshooting communication problems, it is essential to narrow the range of possibilities, and you should start by making sure that your device is working properly.
After making sure that your device your working, you should check your infraestructure.
Assuming that the problem is not related to your device (physical problem) and that your infraestructure is fine, it can only be some sort of configuration problem:
A transaction is defined by any data message from approved and certified POS equipment with the CloudWalk Framework and an operational application installed that is integrated with CloudWalk's servers and our customer's authorisers, via an applicable telecommunications channel.
Note: all transactions conform to PCI standards and additional CloudWalk security protocols, being private and exclusively accessible by the customer.
No, CloudWalk provides only the service. However, if you need to buy POS terminals, you can get in touch and we will be more than happy to help you out!
No, authorizer development and maintenance is the customer's responsibility.
