GraphQL API

Overview
As of version 7.0.0, WorkflowGen features the new GraphQL API, which is a modern solution to create process-driven solutions such as mobile apps, web apps, and microservices that require a powerful workflow and BPM engine.
The WorkflowGen GraphQL API is a Node.js application that runs in IIS using iisnode. It enables a high level of customization such as extending the GraphQL schema with custom types, queries or operations, or implementing new authentication methods.
About GraphQL
From the GraphQL website presentation:
"GraphQL is a query language for APIs and a runtime for fulfilling those queries with your existing data. GraphQL provides a complete and understandable description of the data in your API, gives clients the power to ask for exactly what they need and nothing more, makes it easier to evolve APIs over time, and enables powerful developer tools."
GraphQL is a production-ready and an open source technology created by Facebook. In September 2016, GitHub announced its GraphQL API.
"We’ve often heard that our REST API was an inspiration for other companies; countless tutorials refer to our endpoints. Today, we’re excited to announce our biggest change to the API since we snubbed XML in favor of JSON: we’re making the GitHub API available through GraphQL."
GraphQL is a modern API solution for React, React-Native, Angular 2, and Vue based applications.
Many GraphQL tutorials are available, it is available in many languages, and has a large community.
Technical requirements
In addition to the standard WorkflowGen installation, the following components are required:
​Node.js v14.15.1 LTS

​iisnode

​IIS URL Rewrite

​Visual C++ Redistributable

✏️ Note: This library is required if you encounter the error The specified module could not be found regarding the edge and edge-js libraries when accessing the /wfgen/graphql, /wfgen/hooks, or /wfgen/scim web apps. 
For information on the installation procedure, see the WorkflowGen Technical Guide.
Endpoints
The following endpoints are available:
GraphQL API: http://localhost/wfgen/graphql
GraphiQL IDE: http://localhost/wfgen/graphql
GraphQL Schema (definition language): http://localhost/wfgen/graphql/schema
The HTTP GET method is supported on queries only. The HTTP POST method is supported on queries and operations.
HTTP usage
​Express-graphql is used to serve the GraphQL HTTP queries:
GraphQL will first look for each parameter in the URL's query-string: /graphql?query=query+getUser($id:ID){user(id:$id){name}}&variables={"id":"4"} If not found in the query-string, it will look in the POST request body. If the POST body has not yet been parsed, express-graphql will interpret it depending on the provided Content-Type header:
application/json: the POST body will be parsed as a JSON object of parameters.
application/x-www-form-urlencoded: this POST body will be parsed as a url-encoded string of key-value pairs.
application/graphql: the POST body will be parsed as GraphQL query string, which provides the query parameter.
Using GraphiQL IDE in a web browser
You can use GraphiQL, "a graphical interactive in-browser GraphQL IDE", to test queries and operations, and to browse the schema documentation.
As of WorkflowGen version 7.15.0, the GraphiQL tool is disabled by default. You can enable it in the GraphQL section on the Integration tab in the Configuration Panel. You can also enable GraphiQL in the WorkflowGen web.config file by setting the GraphqlGraphiqlEnabled parameter to Y.
Configuration
Maximum query content length
The maximum GraphQL query content length can be set by configuring the maxAllowedContentLength property in the WorkflowGen web.config file. The following example shows how to configure this property as 1 MB (note that the value should always be specified in bytes, so the value in the example is 1,024,000 bytes). The default value is 30000000 bytes.
1
<system.webServer> 
2
    <security> 
3
        <requestFiltering> 
4
            <requestLimits maxAllowedContentLength="1024000" /> 
5
        </requestFiltering> 
6
    </security> 
7
</system.webServer>

Input file allowed folders
You can configure the local or remote folder paths where files used by FILE type parameters are located using the Input file allowed folders setting In the GraphQL section on the Configuration Panel Integration tab. (Alternately, you can add the folder names separated by commas to the GraphqlInputFileAllowedFolders parameter in the WorkflowGen web.config file.)
When using file uploads, you don't need to include the original file folder.
To disallow input file allowed folders, leave this field empty. To allow certain folders only, enter comma-separated values according to the table below:
Value
Description
Empty
No folders allowed
*
All folders allowed
c:\*
All folders on drive c:
c:\Inetpub\*
All subfolders in a specific folder
c:\Inetpub\folder*
All c:\Inetpub folders whose names start with folder
📌 Examples:
c:\Inetpub\folder1 
c:\Inetpub\folder1\abc 
c:\Inetpub\folder2
c:\Inetpub\folder2\abc\def
Specific folder only
Input file allowed HTTP URLs
You can configure allowed HTTP URLs for input files using the Input file allowed HTTP URLs setting in the GraphQL section on the Configuration Panel Integration tab.
To disallow file uploads using HTTP and/or HTTPS URLs, leave the field empty. To allow certain URLs only, enter comma-separated values according to the table below:
Value
Description
Empty
No HTTP or HTTPS URLs allowed
*
All HTTP and HTTPS URLs allowed
https://*
HTTPS URLs only
http://*
HTTP URLs only
http://mydomain/*
HTTP from a specific domain only
http://mydomain/folder/*
HTTP from a specific folder only
http://mydomain/folder*
All files and folders whose names start with folder
📌 Examples:
http://mydomain/folderfile.jpg
http://mydomain/folder/file.jpg
http://mydomain/folder2/file.jpg
http://mydomain/folder/file.jpg
Specific file only
Maximum input file size
In the GraphQL section on the Integration tab in the Administration Module Configuration Panel, enter the maximum input file size in kilobytes in the Maximum input file size (kB) field.
Alternately, you can set the maximum input file content size in kilobytes as the value of the GraphqlMaxInputFileSize parameter in the WorkflowGen web.config file.
Maximum input file content size
When working with FILE type parameters content encoded in base64, you must enter the maximum input file content size in kilobytes in the Maximum input file content size (kB) field in the GraphQL section on the Integration tab in the Administration Module Configuration Panel.
Alternately, you can set the maximum input file content size in kilobytes as the value of the GraphqlMaxInputFileContentSize parameter in the WorkflowGen web.config file.
FILE type data content is only recommended for small files under 1 MB.
Performance tuning
WorkflowGen is installed with the following default GraphQL settings (located under iisnode in \wfgen\graphql\web.config):
1
nodeProcessCountPerApplication="0"
2
maxConcurrentRequestsPerProcess="1024"
Copied!
The value of the nodeProcessCountPerApplication setting is set to 0 by default for the best performance in Node.js applications. This creates one node process based on the number of virtual processors that are configured. You can change this value at any time to a custom number of node processes; for example, nodeProcessCountPerApplication=2 will create two node processes independently of the number of virtual processors.
You can also optimize performance if needed by adjusting the maxConcurrentRequestsPerProcess value based on the number of potential concurrent users and requests.
For more information, see the Best practices and troubleshooting guide for node applications on Azure Web Apps Microsoft article.
Cross-origin resource sharing (CORS)
In order to allow a client application (such as front-end JavaScript code from an outside domain) to access and request data from the API, you must enable and configure the Cross-origin resource sharing (CORS) settings in the WorkflowGen GraphQL API module. To do this:
1.Install the IIS CORS Module on the WorkflowGen web server.

2.Add the cors node with the list of external domains and their methods and headers (where HTTP requests will be allowed) to the WorkflowGen web configuration settings (located in \wfgen\web.config). See some common examples below.
📌 Example 1: Allow all origins
1
<configuration>
2
    <location path="graphql" inheritInChildApplications="false">
3
        <system.webServer>

Authentication
The following authentication methods are supported:
IIS Basic
WorkflowGen authentication
Custom .NET authentication modules
OpenID Connect
If your WorkflowGen site is configured with Integrated Windows or Basic authentication, you must configure GraphQL with Basic authentication.
HTTPS is required to secure credentials.
For OpenID Connect providers, you need to pass the access token as a bearer token in the Authorization header; for example, Authorization: Bearer <ACCESS TOKEN>(replace<ACCESS TOKEN> with your access token).
The GraphQL Node.js app code inside the \wfgen\graphql folder can also be customized to accommodate many other authentication methods (such as OAuth2, JWT, etc.) thanks to node libraries such as Passport.js.
System access users
Some operations (such as UpdateRequestDataset) require users to have system access to perform the operations. This can be configured in the System operations allowed users field, under Security on the Integration tab in the Configuration Panel.
User impersonation
User impersonation is supported but not recommended, and should be used only when no other technical solutions are possible. (For example, OpenID Connect-based authentication methods allow you to use access tokens to perform API operations on the client and server sides without impersonation.)
System operations allowed users can impersonate another WorkflowGen user account by setting this account's username as the value of the x-wfgen-impersonate-username HTTP request header.
This request header can be renamed according to your naming convention. You can specify a new header name in the GraphqlImpersonateUserNameHttpHeader setting in the \wfgen\web.config file (e.g. <add key="GraphqlImpersonateUserNameHttpHeader" value="my-custom-impersonate-username" />).
To give or withdraw system operations rights to or from specific users, refer to the System operations allowed users setting in the Security section on the General tab of the Configuration Panel; alternately, you can edit the ProcessesRuntimeWebServiceAllowedUsers setting in the \wfgen\web.config file.
Delegation mode
Some GraphQL queries and operations can be executed on behalf of another user. This is possible when a user has created a delegation in WorkflowGen. The delegatee has to specify the user ID of his delegator in the onBehalfOf argument.
List of actions to do on by the delegatee on behalf of the delegator with the user ID VXNlcjoy:
1
{
2
  viewer {
3
    actions(filter: {as: ASSIGNEE, status: OPEN}, onBehalfOf:"VXNlcjoy"}) {

}
Copied!
When the onBehalfOf argument is set, it is propagated implicitly to the all the sub-queries and fields until a User type is used.
Global identifiers
Each GraphQL type has an id: ID! field. This ID is global and is unique for all WorkflowGen objects.
You can use the node(id:ID!) query to retrieve a WorkflowGen object by its ID.
1
{
2
  node(id: "UHJvY2VzczoxNQ==") {
3
    id
4
    ... on Request {
