This chapter contains generally applicable information on API design. When using Ory services, one can expect a consistent experience when interacting with REST APIs.


On REST endpoints that are explicitly labeled as such, pagination information is available through the Link HTTP header.

The Link header contains a comma-delimited list of links to the following pages (where applicable):

  • First
  • Next
  • Previous (prev)
  • Last

Pagination is done based on per_page and page parameters provided in the querystring, where per_page is the page size, and page is the current page.

Ory's APIs use rfc3339 as the date format:
