Centralised swagger for multiple drop wizard services - swagger

I've included swagger bundle in each of my dropwizard service. I was wondering if we can run swagger independently and connect to each service so that user can have a centralised view of all services through one UI.

I'm not aware of something that lets you do that at the moment with Swagger UI specifically, but you might check out DynamicApis.com. They let you host multiple swagger documents and provide some really nice additional value for your APIs as well. They take your Swagger JSON and build you your own API portal out of them. They also have native REST API integration where you can automatically sync up your API to your portal or you can manually upload them.
Here is an example portal they have up to demonstrate how multiple APIs can be hosted and how you see them.
Here is an example of what their documentation for each API looks like. Kind of like Swagger UI++.

You can have multiple swagger instances in a single DW service. The UI, however, does not allow you to point to each of them independently. It's easy enough though to modify index.html to allow the user to select the swagger definitions that you have in the deployment.

How to merge/aggregate Open API specs from multiple apps in an automated way

The company I work for has a set of microservices that each focuses on a different business capability e.g. payments, transactions, accounts, etc.
We create Open API specs in Swagger Hub (API first design) for each business capability.
Our services are predominantly .NET Core applications running in Kubernetes and we use the Swashbuckle.AspNetCore library to auto generate the Swagger UI from the yml spec (which we copy across manually from Swagger Hub). We've also discussed using .NET attributes to auto-generate the OASs from code, which I'll bring up again below.
Our public clients (native apps & web SPAs) consume multiple business capability APIs and it doesn't really seem optimal to give the public client developers (who are mostly outsourced) multiple OASs i.e. one per business capability. There's also multiple partnerships in the works and I don't think it would look professional to give them 15 different API specs... Ideally we'd have a single API spec for each specific type of consumer (e.g. "Product X public client API", and/or "Product X back-end integration API") that can be broken down into separate categories for each business capability e.g:
Also, some of the operations on a specific business capability might be for different consumers (e.g. public clients or back-end integrations). We could probably work this out by the security scheme (i.e. whether user tokens or M2M tokens are required):
If we continue with the current approach of defining API specs in Swagger Hub for each business capability, we'll need to create an additional aggregated (and partially duplicated) API specs targeted at specific consumers that we would need to continually update manually.
We could switch to defining the aggregated (consumer focused) APIs specs in Swagger Hub, but then we'll need a different way to generate Swagger UI in the microservice applications. Perhaps we could use the attribute based approach mentioned previously to generate the Swagger UI for microservices, but then there's no guarantee it will perfectly align with the aggregated OAS defined in Swagger Hub... before we rush head first down this path, the question is;
Is it possible and are there any tools to merge separate OASs in an automated or semi-automated way (ideally with some basic filtering capabilities i.e. to filter operations based on security tags) so that we don't need to maintain separate aggregated OASs manually? Alternatively, are there any other approaches to solving this problem in a more automated way?

You can use APIMatic's API spec merge feature to automatically merge your specs and then transform the merged output into OpenAPI's format. Here are the steps:
Structure your directory as follows:
dir\
accounts\
openapi.json
payments\
openapi.json
transactions\
openapi.json
APIMATIC-META.json
A minimalistic metadata configuration file APIMATIC-META.json can look like this to enable merging:
{
"MergeConfiguration": {
"MergedApiName": "Product X",
"MergeApis": true,
"MergeSettings": {
"SkipCodeGenValidation": true
}
}
}
ZIP the directory, upload it and transform it via their website to OpenAPI v3 to get your merged output. Here is a link that provides step by step guide on uploading and performing a transformation manually through the website: https://docs.apimatic.io/manage-apis/api-merging/#transforming-the-zipped-file. Since you are looking for automation, APIMatic has an API to achieve the same too: https://www.apimatic.io/docs/api#/http/api-endpoints/transformation/transform-via-file
ideally with some basic filtering capabilities i.e. to filter operations based on security tags
An OAS API spec you provide in the directory can have a metadata configuration file provided next to it as well which can contain filtering options to take out certain operations. Please see detailed reference document on this here: https://docs.apimatic.io/manage-apis/apimatic-metadata/#filtering-out-parts-of-api-definition-with-metadata
So, your directory structure can then look like the following:
dir\
accounts\
openapi.json
APIMATIC-META.json
payments\
openapi.json
APIMATIC-META.json
transactions\
openapi.json
APIMATIC-META.json
APIMATIC-META.json
The inner metadata files can have a configuration like the following:
{
"KeepEndpointsWithTags": ["public"]
}
When you ZIP the directory, upload and transform it, the output OAS would be the merged output of your "filtered" input OAS files. Note, however, that this filtering isn't based on security level information. It is based on the tags configured at operation level.

Is there a provision to import or publish external swagger json/yaml in bloomreach/hippo cms?

The API is hosted outside the CMS and we have swagger JSON/YAML exported fro the API. Requirement is to publish only swagger documentation/spec in Bloomreach/Hippo cms.
Is there an inbuilt capability to directly import swagger json into Bloomreach/Hippo cms and publish the documentation?
I'm sorry you never got a timely answer here. AFAIK there is no ootb functionality for what you want. You can write code to perform this task, either as a service that polls your api or as a rest endpoint where the data can be pushed to. This will have to be translated to a cms document type.

Third-party services integration with Jira through REST API

I’m trying to integrate a third-party tool with Jira server via REST API.
Currently we have a customized Jira used by our client with a business specific issue types.
Basically all I need is to be able to create an issue of a given type, get response (success/error) and get metadata (list of required and optional fields) for that tool via REST API.
We have a create issue page on WebUI, where user can submit his request.
But the problem is all validation logic is “smashed” between some Javascript code, Behaviours and SIL Programs Manager add-ons, AJS scripts, Jira native fields configuration etc.
So I can’t use “plain” Jira REST API directly because it creates issues without taking in account business rules of a given issue type - e.g. requires fields, one fields can have values depending on another field’s value, an attachment is a required as part of an issue etc.
My question is what is the best way to make an integration with Jira.
I want to be sure if someone will try to create an issue via REST API, the data is consistent according to the issue business rules.
I was thinking to write some "proxy" REST API, which will do the all validation needed and create (or edit) / reject the request.
We've developed a separate Jira plugin which serves some scenarios. So, I can add those API to the plugin.
Or, use Jira REST API endpoints like POST /issue (and PUT /issue/), and I have to define a new screen for it, set all required fields via standard Jira settings, set Cascading fields rules and the standard validator will check if everything is ok out-of-the box?
Sorry, I’m new to Jira and not sure if my current understanding is correct now.
Thanks
Tricky. Best to validate the data in a single place (with one set of code) before calling the create REST API. That way you can also modify the validation logic more easily over time. I think I would probably define a new REST endpoint. ScriptRunner lets you script that nowadays

Workday - How to programmatically get list of WSDLs in Workday

I am working on developing an integration with Workday. Under my initial analysis, I found that Workday provides multiple wsdls for different modules like "Human resource", "Inventory" etc. I can see this complete list at https://community.workday.com/sites/default/files/file-hosting/productionapi/operations/index.html
I am trying to understand how I get get this list progamatically in my integration so that my user can select one of the wsdls rather than typing in the full name of WSDL. Please share your thoughts on this.
You can programatically retrieve a list of all web service operations by creating a Custom Report based on the "Public Web Services" data source. The report can then be exposed as a RESTful WS for easy retrieval.
Some fields you can include in the report are: Web service, supported operations, api version, endpoint url, WSDL url, etc, etc.
This is highly customisable, in the sense that you can query the RESTful WS Report for specific versions, specific operations, etc, via Prompts / URL Params.
The report-as-a-service, supports also a variety of output formats as well as its own WSDL.
The purpose of a SOAP WSDL is to generate a client stub, i.e. a model that lets your client interact with objects exposed or consumed by the service provider. You don't interact with a WSDL at runtime - you interact with the stub. If you want to make multiple services available, you have to include each WSDL in your client application at compile time and generate their stubs. The services in a given API version do not change, so there isn't a reason to do this dynamically.
To add to the query asked, what we are trying to understand is that whether there an API call/request which we could hit to get the list of web services available to populate it on the UI to select from it.
For Example: In this link, https://community.workday.com/sites/default/files/file-hosting/productionapi/index.html, we have Absence_Management, Academic_Advising, Academic_Foundation and so on and Now, if I want it to be displayed to the end user so that He can select the webservice to be used and accordingly we could download the WSDL as to work on it.

How to create Swagger doc from multiple swagger files

I defined APIs through swagger. For each micro-service, I have a swagger file say micro-service1.yaml.Like that I have around 40 micro-services. Accessing each one is difficult . I want to access all of the through a common URL.How can I achieve the same. Thanks in advance!
One option is to use WebSphere Liberty, since it will aggregate all the APIs running in it and show you them in a single Swagger UI.
However, for 40 micro-services the recommended topology would be to separate them into different WebSphere Collective members (Java w/ Liberty or Node w/ Loopback), where either of them can be inside a Docker container), so you could see all the APIs from the aggregated Collective Controller Swagger UI.
