The VPD Playground is a graphical web interface that lets you write and run GraphQL queries against the VPD service, without needing to write code or start an HTTP client. Ideal for exploring the schema, testing queries and quickly viewing results.

The Playground is available on the VPD website:

You need valid OAuth2 credentials to use the Playground. Log in with your client credentials (scope vpd) to start a session.

The Playground provides an editor with syntax highlighting and autocomplete for GraphQL. You type your query in the left panel and see the result directly in the right panel. The key capabilities:

• Explore the schema: the built-in documentation explorer shows you all available fields, types and search parameters
• Write and run queries: type a query, press the play button and view the result as JSON
• Use variables: define variables in the variables panel to make queries reusable
• Inspect results: the JSON result is directly readable in the interface

Open the Playground, authenticate with your credentials and run this query, for example:

{
  parties(name: "eConnect", country: "NL", maxResults: 3) {
    legalName
    partyIds {
      type
      value
    }
    locations {
      city
    }
  }
}

The response appears directly in the right panel. You will see the legal name, identifiers and city of the organisations found.

On the right side of the Playground you will find the documentation explorer. Click on a type or field to see the available sub-fields. This is the quickest way to discover what data is available, without consulting the API documentation separately.

The explorer shows the complete party schema including field types, descriptions and whether a field is optional. Use this as a reference when building your queries.

Always test on the acceptance environment (accp-vpd.econnect.eu) first before running queries in production. Use the maxResults parameter to limit the number of results during testing. And make use of the autocomplete in the editor: it saves typing and prevents errors in field names.
