Frequently Asked Questions

Building your application

Yes, you can. The power of WEM is modeling your own application. You know best how your processes work and how they should be digitized. Using our online tutorial combined with the online documentation will get you started and if needed there are additional training courses. This way you can model your own application.
Yes. This is what WEM is all about. You can easily create your processes in WEM using the drag-and-drop functionality of our Modeler. These processes are then turned into an application that is fully based on the processes as you defined them. And these processes can be very simple, or really complex: WEM supports it all.
You don’t. WEM is delivered as an aPaaS (Application Platform as a Service) solution. Therefore, you do not have to install anything. WEM is accessible through your browser and we take care of all the platform and software management. This way you can focus entirely on building and using your applications.
Yes, this is possible. In fact, there is no limitation to the number of people that can work on the same project. The owner of a project can invite as many people as needed to work on the same project, and give every person a specific role within the project. Read more on this topic.
This is certainly possible. WEM has a network of partners that are specialized in building WEM applications. You can contact a WEM partner in your region and work with that partner to build the application(s) you need.

Licensing and costs

WEM has a "pay-per-use" licensing scheme. You pay based on the application usage. We measure the usage by counting the number of events your application generates, and charge you per event. The more events you have, the lower the price per event. An event is generated every time you load a page, use webservice, OData or HTTP, generate an email or PDF document.
WEM licensing is based on the usage of the application(s) you have built. The usage is measured by the number of events the application(s) generates. An event is e.g. the creation of an email, using a webservice of loading a page. Detailed license information can be found on our license details page.

The WEM Modeler is free to use. Without any restrictions. So go ahead and model your own applications!

WEM offers a full DTAP (Development, Testing, Acceptance and Production) solution. You start modelling your application in the test & development environment. Using the test & development environment is free, so there are no costs associated with building your application.

Once you are ready to share the application with others for acceptance testing, you publish your application to the staging (acceptance) environment. And when you are ready to go live, you publish to the production environment. Publish to staging or production requires a WEM license, and even then you only pay for what you use.

Check the license information for more details on WEM Licensing.


Yes, that is possible. Within WEM modeler is an option to send email. You can control all relevant fields to send email: "To", "From", "Subject", the message body, and many more, directly from your WEM application. So you have full control over the email message.
Yes, WEM has a Calendar Widget you can use in user interaction screens.
WEM has a (Google) locator feature that is available as an advanced input widget.
Yes, WEM uses a language dictionary which can support any language. Simply add your own application content to the dictionary. The WEM modeler can then be used to access the language dictionary to dynamically retrieve the content based on the user specified language.
Yes. WEM offers the ability to import Excel or CSV files. You can also export data to Excel or CSV files.
No, you cannot use the formulas from Excel with the OData link feature. You can only use the data in Excel.

Look & feel

Yes, you can. Every WEM application uses a master template that defines the look & feel of that application. You can use one of the templates that is available out-of-the-box, or a new master template is created that defines the look & feel you want.
Yes, that is possible by using the concept of 'portals'. A portal is an instance of an application that has its own look and feel and its own database and its own functionality if needed. Build your application only once, and then create a portal for each instance of the application. Every department can then have its own instance of the same applications. It works the same, but can have a different look & feel, and its own data.
Yes. The underlying technology for the frontend is bootstrap. This, together with specific WEM features ensures that your app is responsive and will offer the best possible experience on any device you want to use the application.
Yes, you can build native apps with WEM. You can develop your web application the same way in WEM as you usually do. After finishing and testing your application you can deploy it as an Android app to the Google Play store or as an iOS app to the Apple App Store.


Security is really important to us, we have very solid security measures at all the levels of our product offering: from the platform/infrastructure, to the WEM runtime and even the WEM applications. We run weekly penetration tests on our solutions, while customer have the ability to request penetration tests for their own applications that are built with WEM.

We support all important industry security standards: contact us if you need more detailed information.

Data is stored in your own local region or as specified by you. Data belonging to US customers is stored in the US, while data from e.g. The Netherlands is stored in The Netherlands. WEM uses local cloud services providers for every region in which we are active, to make sure your data is stored locally.
With WEM you can build almost any application, including a self-learning system. For example: WEM uses Lucene – a text based retrieval API – to smart search and indexing content. Combine this with flow logic and you can create a self-learning system.


Yes. WEM can integrate with a wide variety of systems. To do that, we support SOAP, REST and OData to integrate with external systems. We support the SAML and OAuth protocols in order to realize single-signon functionality with existing systems SAML supports e.g. Microsoft Active Directory, Google G Suite, Oracle, and many more. OAuth supports all social systems like Facebook, Twitter, linkedIn, etc.

Yes, you can publish your WEM application to a specific domain. Before you can use the staging environment (e.g. for acceptance testing) you need to specify the hostname that is used to access the project.

The same applies to the production environment: you need to specify the hostname that is used to access your project in the production environment.

Yes, it is possible to use your own mailserver in WEM projects if you want to use a non-WEM email address as sender. There are 2 ways to implement this:

  1. Using our default mail server. Note that our server must be authorized via an SPF record in DNS from your domain.
  2. Another option is to directly use your own mail server. In WEM you can implement / manage the smtp settings on the workspace level. Note that you have to put our outbound IP address into the IP whitelist on your (customer) firewall.
Yes, this is possible. There are several webservices available that allow you to integrate with Outlook. Using these webservices you can for example create new calendar items in an Outlook calendar using a WEM application. A number of other functions are also available.
Yes, WEM is highly suitable for retrieving external data through web services such as JSON and SOAP but also through OData, which you can use to create dashboards. Here is an example in WEM:
Yes, WEM supports all relevant ways to implement single sign-on. We support both the SAML as well as the OAuth protocol in order to realize single sign-on functionality with existing systems. SAML for example supports Microsoft Active Directory, Google G Suite, Oracle, and many more. OAuth supports social systems such as Facebook, Twitter, LinkedIn.
Yes, you can use the expose webservice feature in WEM combined with import data node to do this.
You can create custom pick lists. To do so you create a list in the data model environment of WEM thus not requiring the use of our ontology features. Present your data in a datagrid and make every row clickable.
See also the answer to the question: "I want to use pick lists, but I don't want to use the ontology feature of WEM?" To use the external data, you will have to import your data into the WEM data model lists, or use web services, or use OData. You can import your external data into WEM data model lists in several ways, or import in into the Ontology. Once you have imported the data into either a data list or the Ontology, you can create picklists based on the imported data.


Yes. WEM is delivered as an aPaaS (Application Platform as a Service) solution. That means that every new update (including new features) is automatically available to all WEM users when the update is released.
All our customers automatically enroll in an escrow arrangement that guarantees the continuity of the WEM platform and your applications.
Yes, we offer several training courses. Since the WEM Modeler is easy to learn, you can also follow the online tutorial and read the online documentation. That will help you to get started fast. And then sign up for a training course to cover more advanced topics.
