Migration from ZUERST to Ginto

Migration from ZUERST to Ginto

The ZUERST accessibility database from Pro Infirmis has been fully integrated into Ginto. As a result, all data previously collected by Pro Infirmis via ZUERST is now available in Ginto and can be accessed directly through the Ginto platform.
Before you start

The Pro Infirmis ZUERST API will be shut down at the end of 2026, making a timely migration to the Ginto API necessary. The Ginto API provides the same data as the previous ZUERST API, albeit with a slightly different structure. Ginto also offers additional accessibility information, such as data from hotels or museums that have self-reported their details as part of the OK:GO initiative. This guide provides a step-by-step explanation of the migration process from ZUERST to Ginto.

note

Ginto consolidates leading software solutions and existing data onto a single central platform. Ginto is managed by the Sitios association, which was founded in 2022 by the Förderverein Barrierefreie Schweiz, Pro Infirmis, and the AccessibilityGuide association. Its goal is to coordinate and further develop the range of accessibility information available in Switzerland.

Professional tip

ZUERST will be phased out according to the following schedule:

  • Effective immediately: Accessibility information still being collected by Pro Infirmis via ZUERST remains accessible through the ZUERST API, but is also fully integrated into Ginto and can be retrieved directly via the Ginto API. The majority of professional data collection by Pro Infirmis is already being conducted using Ginto.
  • December 31, 2026: The Pro Infirmis ZUERST API will be set to standby mode. POI requests will be redirected to the corresponding Ginto URL. No further accessibility information will be collected using ZUERST.
  • December 31, 2027: Complete shutdown of ZUERST, including the API.

Frequently asked questions

Get API key

To migrate seamlessly from ZUERST to Ginto, you will need an API key and a publication filter.

    The API is protected and can only be accessed if the request is authenticated using an API key. Please contact support@ginto.guide to obtain an API authorization key. You can then use this to retrieve all data from the Ginto API. The API key must be included in the Authorization header as a Bearer token with every request.

    To ensure you receive the exact same information from Ginto as you did with your previous ZUERST queries, our support team will be happy to create a publication filter for you and send you the corresponding filter ID. Please let us know which query you have been using to retrieve your data.

    Alternatively, the Ginto API offers various options for filtering data directly according to your own criteria during a query. You can find more information on this in our API documentation.

    API - Retrieve data

    Use the following query to retrieve the data for your organization's entries. Replace "filterId" with the number you received from the Ginto support team in the first step.

      API - Adjust code

      Adjust your code to read the data from the new response structure. The following table shows where the data was previously located in the ZUERST JSON response and where it is now located in the Ginto API response.

        API - Assign categories

        ZUERST and Ginto use different categories. The following overview shows the mapping of ZUERST categories to Ginto categories:

          Apply for OK:GO proof for ‘Swisstainable’

          OK:GO is recognised as proof within the ‘Swisstainable’ sustainability programme at Level II – engaged (in combination). An overview of all recognised sustainability certificates can be found here.

          An OK:GO certificate for participation in ‘Swisstainable’ can be applied for using this web form. A certificate will be issued once the conditions of participation have been met. The OK:GO certificate is valid for two years from the date of issue.
          Thank you, we've received your request and will get back to you in the coming days.
