Try PSB endpoints live on the page: one showcase endpoint, an inline embed and a full OpenAPI group.
This page contains live API blocks that fetch the OpenAPI specification client-side. On first display you briefly see a loading state; after that you can fill in parameters and use Try It Out. For the full endpoint overview see the API Reference.
One endpoint as a fixed showcase (two columns: documentation on the left, live form on the right).
Same kind of reference, lighter: a collapsible accordion inline in the body text.
All operations under the OpenAPI tag Peppol, automatically kept in sync with the specification.
Some endpoints are also available in the beta spec (v1-beta). Set version="beta" on the block.
