Incoming Webhooks

Overview
WorkflowGen features an incoming webhook application that allows users to interact with WorkflowGen from external sources by exchanging JSON payloads using HTTP POST requests. The application supports multiple types of operations, such as creating a new request, completing an action, and some process deployment operations like creating a new process from an XPDL.
Technical requirements
In addition to the standard WorkflowGen installation, the following components are required:
​Node.js v14.16.1 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.
Configuration
Maximum query content length
The maximum query content length for incoming webhooks 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 30,000,000 bytes.

<system.webServer> 
2
    <security> 
3
        <requestFiltering> 
4
            <requestLimits maxAllowedContentLength="1024000" /> 
5
        </requestFiltering>

    </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 Webhooks section on the Configuration Panel Integration tab. (Alternately, you can add the folder names separated by commas to the HooksInputFileAllowedFolders 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 (or the parameter undefined). 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 Webhooks section on the Control Panel Integration tab.  (Alternately, you can add the folder names separated by commas to the HooksInputFileAllowedHttpUrls parameter in the WorkflowGen web.config file.)
To disallow file uploads using HTTP and/or HTTPS URLs, leave the field empty (or the parameter undefined). 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 Webhooks 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 HooksMaxInputFileSize 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 Webhooks 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 HooksMaxInputFileContentSize 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 webhooks settings (located under iisnode in \wfgen\hooks\web.config):
1
nodeProcessCountPerApplication="1"
2
maxConcurrentRequestsPerProcess="1024"
Copied!
With these settings, only one node.exe instance will handle HTTP requests. This should be sufficient in most cases, but you can optimize performance if needed by adjusting these values based on the number of potential concurrent requests.
Creating an incoming webhook application
To create a new incoming webhook application in your WorkflowGen application, click the Add Application button on the Applications page. Then, choose Incoming webhook from the Application type drop-down list, enter the Name and Description, and click Save.
The Applications page will now display your incoming webhook application information, including the application URL. This is the URL you should use to send WorkflowGen incoming webhooks. The last component of this URL corresponds to a token that WorkflowGen will use to identify your incoming webhooks.
You should fill in the Impersonate username textbox with the WorkflowGen username you use to perform your desired operations. Be aware that your impersonated user must have your asked-operation-required rights to complete the action; if not, you will receive a security error on your response payload. As well, if the impersonate username is not set, the workflow engine service default identity will be used (as defined in the Security section on the Integration tab in the Configuration Panel).
The generated URL and its associated token must remain private and not exposed to end-users in client-side (in JavaScript, for example). You should treat the token with the same level of security as you would a password.

If the token used in the incoming webhook URL is missing or invalid, a 404 status code will be returned. If the associated user is invalid, archived, or inactive, a 403 status code will be returned. In both cases, the response will contain a descriptive error message.
Sending data in JSON
The incoming webhook application receives your HTTP POST request payload formatted as a JSON object.
Using the URL provided, you can post HTTP requests from external applications (e.g. Postman) to WorkflowGen in order to execute the available operations in your WorkflowGen application. For operations that require you to provide an object ID, the object ID value can be retrieved by using the GraphQL API. In most cases, object numbers can be used instead of IDs in operation payloads.
In case of an error, you will get a response payload providing error details such as:
1
{
2
  "error": "Advantys.Workflow.ServiceFacade: CreateRequest error: A process ID or name is required"
3
}

Curl example
The requests should respect the structure shown in this example, where operation refers to the name of the operation to execute, and args contains the input node that groups all of the request parameters to perform the operation.
To create a new request, the processName parameter is required. The processVersion parameter is optional and is used to find the correct process you want to use to create your request.

OpenAPI v2 endpoints
As of version 7.17.0, incoming webhooks now offer a new endpoint that supports the OpenAPI v2 specification for operation definitions and another endpoint for operation execution. This allows for seamless integration with other OpenAPI-ready solutions such as Swagger, Microsoft Flow, Azure Logic Apps and Postman.
Webhook operation definitions
Use this endpoint to retrieve webhook operation definitions based on the OpenAPI v2 specification (in JSON format).
1
URI: /wfgen/hooks/openapi/v2
Copied!
Webhook operation execution
Use this endpoint to execute a webhook operation using HTTP POST, replacing :operation with the name of the incoming webhook operation (e.g. createRequest).
1
URI: /wfgen/hooks/operations/:operation
Copied!
Required parameters
:operation: Name of the incoming webhook operation defined in the URI

✏️ Note: The operation name is not required inside the request payload.

x-wfgen-hooktoken: Webhook token value specified in the HTTP request header, which is the same token value as used in a classic incoming webhooks URL

Properties with an asterisk * next to their name 
Other required or optional parameters specific to the webhook operation might be needed.
Request operations
Create a new request
To create a new request from the webhooks API, make sure that sub-process mode is enabled with public access on the target process. (See the Process form section in the WorkflowGen Administration Guide for more information.)
