There are articles part 1-3[1] that will help you. The convention is for
POST to create a resource, POST to update a resource, GET to retrieve,
and DELETE to delete.

But you can do anything you want.

If you want to use GET, you would have to pass the data as query
string.

I'm new to this so I'm trying to understand.
If I want to return rows, normally I would use a GET. But since one of
my
input parameters is a structure I'm forced to either use a POST or a
PUT.
So I'm sort of forced out of the convention that GET is to read records,
POST is to create records and PUT is to update records.
So it's ok to do a POST only to read records?

Is there anyone else using IWS from an RPG perspective that has found or
could share some useful information?

Thanks,

Rob

the suffix _LENGTH must be capital because that is what IWS
currently
looks for. It should not matter because it is not part of payload.

If you have a structure that is an input parameters, then the HTTP
method
is POST or PUT.

Other than what we have for doc on web site, and articles, that
is
all the doc there is. We are in process of updating the doc.

@Nadir, your assumption is correct, pFilterDs is indeed input. So
you
are
saying that I can have a data structure as input?

Why must the "_lenght" be in upper case. I've never seen nor
understand
this requirement.

Thanks,

Rob

Which parameters are input and which output?

And "_length" suffix should be "_LENGTH"

Assuming pFilterDs is input, you may want to define a length
field
for it as well so that you know how many entries are being
passed
in.

I want to have a filter(s) for my api.
An individual filter is defined as

dcl-ds filterTmp template qualified;
type char(20);
value char(20);
end-ds;

But there may be multiple occurrences of filter. For example,

'Warehouse': '95,96,97'
'Type':'Shipments'
'DateRange': 'LastWeek'

I was hoping to do something like
dcl-pi *n;
pFilterDs likeds(filterTmp) dim(10) const;
transactionDs_length int(10);
transactionsDs likeds(transactionsTmp) dim(1000);
httpStatus like(httpStatusTmp);
httpHeaders like(httpHeadersTmp) dim(10);
end-pi;

But when I try this on Step 5 of 9 on the Deploy New Service
Wizard
I
get
error
*Error:* ZUI_54411: The HTTP method must be PUT or POST when
there
is an
input parameter that is not being injected with a value.

How should I be doing this?
