Hi,
Looks like bug 28369 is moving in the right direction. Whatever is
eventually done, it's important to not just remove or change existing
API functionality in the current API version. An API version should
remain back-compatible. Functionality can be deprecated, but it should
not be removed between Koha versions.
I think Innovative has found an acceptable balance with their Sierra
REST api versioning and deprecation policy. I'm not sure of all the
details, but basicly they've added a new version whenever there's a
backwards-incompatible change and kept the older API versions available
for a few versions. Then the oldest one gets deprecated, and in the next
major version or so it is removed. They also indicate which one is the
recommended API version to target.
A further note about the holds API endpoints: I can see the reasoning
behind the different endpoints for suspension, priority etc. but from an
API user's endpoint it's really convoluted to use. I'd really like a
PATCH method that would allow one to update priority, suspension and
it's end date and pickup location in a single request.

Hi Thomas, David,
I vote for making it a PATCH route and either document the PUT method as
"do-not-use" or making it a real "PUT".
In my opinion making the api a v2 is going to make things confusing for
consumers as there are already several web-services available for Koha
(ILS-DI, OAI-PMH, SRU, Rest...).
For each API version, consumer app must develop a new connector and a
mechanism to select which connector is appropriate to use, this is going
to be quite confusing + added complexity for api consumers.
Unnecessary complexity in my opinion.

One comment I would have is… what is the threshold for creating a V2
of the REST API?
And maybe a breaking change for the API is OK for a major version
change in Koha but just not a minor version change? (That said, I’ve
encountered breaking changes in PostgreSQL on minor version updates.
They’re annoying, but they are a fact of life I suppose.)

Hi all, I wanted to gather some opinions about the mentioned route.
We've made sure all routes have the additionalProperties: false
setting, and some routes, like this one, don't have it. In the task to
add it we noticed:
1. Theroute doesn't work as expected: the documented attributes don't
match the coding guidelines (i.e. terminology hasn't been adjusted on
the spec) but it did in the code, it just works because we don't set
additionalProperties: false. TL;DR no one following the spec can use it.
2. The route seems to be wrong regarding how our RESTful
implementation works in the rest of the routes: PUT should get a
Koha::Hold object for updating it. Instead, it only 'accepts':
'priority', 'pickup_library_id' and 'suspended_until'. If we wanted to
allow to selectively change those attributes, we should do a PATCH
instead.
3. We already have individual routes for changing those things on the
hold:
PUT /holds/:hold_id/pickup_location
PUT /holds/:hold_id/priority
POST /holds/:hold_id/suspension
The route itself doesn't work now. And any change will break things
for people 'using' it. And tests pass only because the spec is loose.
The options are:
- 'Fix' the route so the attributes match the code, i.e. change the
spec as bug 20006 intended to do.
- Leave it as-is (probably documenting it should not be used).
- Remove the route until we really need to implement that PUT for
something.
- Make it a PATCH route, in which we could add new attributes without
breaking anyone's dev (besides the verb change, that should be advertised)
- Fully implement a PUT, making it mandatory to send all the
attributes (this would be an important breaking change).
I would vote removing it, or making it a PATCH route. But I still
don't see the use case in the UI, for the latter. Most places in Koha
do atomic updates for priority, pickup location or hold suspension for
which we clearly have routes already.
Looking forward to your comments.
