Accessibility of the API Catalogue for the Data Exchange Layer

This accessibility statement explains how well the API Catalogue online service complies with the Act on the Provision of Digital Services, what shortcomings there are in the accessibility of the website and how you can give us feedback on accessibility problems.

The Digital and Population Data Services Agency is responsible for this online service. We want as many users as possible to be able to access our digital services. We take accessibility into account in the development of digital services.

How accessible is the website?

This online service mostly meets the A and AA level accessibility criteria required by law (WCAG criteria 2.1). The online service has some shortcomings in accessibility, which are described in more detail below.

Did you notice any gaps in accessibility?

We are constantly striving to improve the accessibility of the online service. If you observe any issues that are not described on this page, please let us know and we will do our best to fix any shortcomings. We will respond to requests and comments as soon as possible, but no later than within two weeks.

More detailed information on technical accessibility

The online service is not yet fully accessible. The features listed below are not yet completely accessible.

Navigating the website using a screen reader or keyboard

  • On some pages, the websites elements, such as elements used to control the website or forms, have not been programmed to be connected. Due to this, some pages do not follow a logical order when used with a screen reader. (WCAG 1.3.5, 2.4.5, 2.5.3, 3.3.2, 4.1.3)
  • Some of the forms are not completely accessible. Using the forms with a screen reader or keyboard is difficult and, in some cases, impossible (e.g. the date picker). (WCAG 2.1.1, 2.1.2, 2.1.4, 3.2.4, 3.3.1, 3.3.2, 3.3.3)


  • Some of the images on the website do not have a text alternative. This concerns mostly the organisations’ logos, as it is currently not possible for the user to add text alternatives to them. (WCAG 1.1.1)


  • There are shortcomings in the Swedish translations of the user interface texts. The missing translations have not been programmatically determined to be in a different language. (WCAG 3.1.1, 3.1.2)
  • The previews of APIs following the OpenAPI architecture are presented using the Swagger UI component developed and maintained by SmartBear Software. Some of the headings in the component are not descriptive and heading levels are not used logically. (WCAG 2.4.6) Some of the Swagger UI components and their relationships with each other have not been programmatically determined. (WCAG 1.3.5, 2.4.5, 2.5.3, 3.3.2, 4.1.3)

An effort will be made to correct the shortcomings listed in this statement during 2022.

Accessibility requirements do not apply to certain content

The main content on the API Catalogue is the information about different subsystems and services available through the Data Exchange Layer. This information is provided by the organisations that have joined the Data Exchange Layer and are offering these subsystems and services. These are considered third-party content, and the service provider is not able to make them accessible. The service provider can, however, instruct the users to produce accessible content. You can request the information in an accessible format by contacting the responsible organisation directly.

Not all organisations have published information about themselves or their subsystems and services in Swedish or in English. These descriptions are considered third-party content, and the service provider is not able to make them accessible.

How have we tested accessibility?

We regularly test the accessibility of the online service internally as part of the design and development process.
