The 'REST services' documentation does not fit the current implementation of the koha rest API. For instance, the documentation shows a 'user' endpoint: GET user/byid/:borrowernumber/holds GET user/:user_name/holds GET user/byid/:borrowernumber/issues GET user/:user_name/issues GET user/:user_name/issues_history GET user/byid/:borrowernumber/issues_history GET user/today GET user/all POST user But the endpoint implemented in api/v1 is "patrons", e.g. https://intranet.bywatersolutions.com/api/v1/patrons/221 The best current documentation that I'm aware of is https://wiki.koha-community.org/wiki/REST_api_RFCs It would be nice to build this documentation via api/v1/spec see also bug 17694
https://koha-community.org/manual/17.11/en/html/17_miscellaneous.html?highlight=rest#rest-services is not about our current implementation but about a patch/scripts Biblibre provided in the past to implement a REST API for Koha. I suggest removing that paragraph as Koha's REST API is still being developed and it will be hard to keep up with changes. Fast changing technical documentation seems better suited for the wiki atm.
