Thanks for the response!

I agree with not using it if majority of the APIs will just have to set it to be ignored.

I'm gonna look into private header fields as that seems like a great idea for what we're trying to do.

Good day,

I'm looking for opinions on how to deal with the REST API endpoint authentication in a scenario where it would require JWT validation if a user is logged in, and it would not if they are not logged in.

The few ways I could think of this working is either by:

- Setting Ignore Top Level ...

Weirdly, I got it working in a WAM using the code below.

#xNoteSubject := 'host: apitest.cybersource.com' + (10).AsUnicodeString
#xNoteSubject += 'date: Fri, 21 Mar 2025 04:32:08 GMT' + (10).AsUnicodeString
#xNoteSubject += 'request-target: post /pts/v2/payments/' + (10).AsUnicodeString ...

Good day!

I am working on consuming some REST APIs and am having trouble getting the hashing algorithm to work properly when Line Feeds are involved.

The hashing uses SHA-256 HMAC with the output encoding as Base64. This is the string in the sample provided by the REST API documentation.

Thanks for the response @MarkD.

I did try this with the JSON shown below. The response is too large to post here so I put it up as a .txt file.

"days": [

"ABC123": "ABC123"

Hi @Dino,

Thank you for the response. I've actually done the sample you did in another API as I'm new in learning about the construction of Server Modules as REST APIs.

The current one with issues is actually for a list of categories and sub-categories. Sub-categories will have the same fields as ...

Good day,

I've encountered an issue that only happens when running REST APIs in the IBMi with the response being a custom JSON string.

Thanks for the advice Brendan! The cryptographically secure string does seem more secure and sensible to use.

Thanks for verifying the persistence in REST APIs Brendan!

With regards to the GUID, is it good practice to use the system variable *GUID or *GUID_DB to serve as the key to a table that will help track down persistent values?

Hi,

I'm getting around the concept of LANSA REST APIs now but noticed that there was nothing in the available documentation that mentioned Session Management anymore. I guess this has been superseded by using JWT Tokens at this stage.

How can one persist a value over the server-side for REST APIs ...

Good day. I have a WAM that calls an RP with the definition inside a method routine:


Mthroutine Name(umCheckShipToRDI) Desc('Check Ship To RDI')

Define_Map For(*OUTPUT) Class(#PRIM_ALPH) Name(#oRDI)

Define_Com Class(#RP_GETRDI) Name(#RP_GetRDI)


We got a report that some validation messages ...

Thanks for the response. Apparently, the team has agreed to just limit the searches to 100 for now so we will keep using the current implementation to move things forward.

On the other hand, I could not find any examples on how to use XPRIM_JSONReader. Would there be any examples of this in the ...

Hi Everyone,

I asked a question previously on how to efficiently read JSON data which @Marcus Lancaster was able to provide a solution for.

Now, our team is working on a large set of data with about 500 entries returned and a kind of complicated structure (see a trimmed down version below ...

Thanks for this Marcus. Very interesting as I have never used JSONDocument or JSONMember before.

I'll definitely give this a shot when an opportunity arrives.

Hi Marcus,

Yes I was able to solve it but the solution might not be so efficient. Here is the code I used below:

#JsonRandomAccessReader.SetSourceHttpResponse Httpresponse(#HttpRequest.Response) Errorinfo(#JsonErrorInfo)

If Cond(#JsonErrorInfo.OK)

#FXRETCD := 'NR' /* Set to no parts found ...

Good day,

I have an HttpRequest that responds with a JSON object that looks like this:

Hi Mark.

That is something I have never used nor was aware of. Seems to be an interesting concept.

I am just unsure if that would work while utilizing *ListFields. Ideally, I would have just sorted the LCOL but Sort_List only seems to work for Working Lists. Maybe I will give this a try sometime ...

Thanks again for the response Stewart.

I've never tried sorting Keyed Collections before. Do you mean to create a keyed collection keyed by the field I want to sort on? For example PRIM_KCOL<#Price #RP> Or PRIM_KCOL<#Product #RP>?

Unfortunately, I am a bit tight with my schedule right now so I ...

Hi Stewart. Thanks for the response.

The way I display the list is by having all the data lie in a collection in a data model RP. Then the displayed list is controlled by pagination controls (page numbers, sorting, etc.) and gets only the data it needs to display from the data model depending on ...

Hi,

I am working with a List Collection inside a Reusable Part that acts as a data model shared between components. There is a particular list that can be controlled by a Sort control in one of the Views I am displaying.

Using the Sort_List over the property of the List Collection ends up with ...
