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:
Visual C++ Redistributable ✏️ Note: This library is required if you encounter the error
The specified module could not be found
regarding theedge
andedge-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.
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
):
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, a403
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:
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.
Request payload:
Response payload:
The response payload will be structured as follows:
Parameters
Parameter
Description
processName
Process name (required)
processVersion
Process version, used to find the correct process you want to use to create the request
clientMutationId
This parameter will be null if the request creator did not define it in the request payload
requestId
ID of newly created request
number
Number of newly created request
onBehalfOf
This parameter contains the delegator ID; however, if the request was not created in delegation mode, its value will be null
onBehalfOfUserName
This parameter contains the delegator username; however, if the request was not created in delegation mode, its value will be null
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).
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
).
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 URLProperties 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.)
Request payload:
Response payload:
A parameter's array can be included in the createRequest
operation payload. Be aware that a data with the same name and data type must previously exist in the process for each parameter in the array to store the parameter's value. The following example shows how to send parameters corresponding to the four supported data types (TEXT, NUMERIC, DATETIME, and FILE).

File upload
As of version 7.2.0, the incoming webhook application supports the fileValue.updatedAt
, fileValue.content
, and fileValue.url
fields when sending FILE parameters (as shown in the previous example).
The fileValue.updatedAt
field should use the ISO 8601 date format.
File content
The fileValue.content
field should contain the file content encoded in base64. In this case, the fileValue.url
field is not required. You must set the maximum input file content size (see the Configuration section above for instructions on how to set these).
File URL
The fileValue.url
field contains the file URL. When working with FILE parameters, you must set the input file allowed folders and the maximum input file size (see the Configuration section above for instructions on how to set these).
You can also prevent file uploads using HTTP and/or HTTPS URLs setting the Input file allowed HTTP URLs in the Webhooks section on the Integration tab in the Administration Module Configuration Panel (see Input file allowed HTTP URLs in the WorkflowGen Administration Guide).
The following path patterns are supported:
Local file should use the File URI scheme:
Public file URL:
File URL:
Multipart file upload
Incoming webhooks support multipart file uploads for the following mutations:
createRequest
completeAction
completeFormAction
updateRequestDataset
createProcessFromXpdl
updateProcessFromXpdl
createGlobalListFromXmlDefinition
updateGlobalListFromXmlDefinition
📌 curl example for a single upload
The content type should be
multipart/form-data
.The
payload
field is required and contains the operation and its arguments.input.parameters[X].fileValue
should contain anuploadMap
whose value is the(\"fileValue\": {\"uploadMap\":\"1\" })
key of the file to be uploaded.The key should be an alphanumeric string that matches the file key (
"1"
in the above example).For each
uploadMap
declared, a file with the same key must be attached.
Each file to be uploaded should contain the alphanumeric key and the file path (
"1=@C:\test1.txt"
).Each attached file must match an
uploadMap
.The files should follow the
payload
part.
📌 Curl example for multiple uploads
Limits
The maximum number of uploads in the same request is 30.
The maximum file upload size is set in the
HooksMaxInputFileSize
configuration parameter.
The multipart/form-data
content type is only advised for HTTP requests with file uploads. If the fileValue.name
, fileValue.description
, fileValue.contentType
, and fileValue.size
properties are not defined, they will be set from the uploaded file information; otherwise, they will take the values defined the payload.
Delegation mode
Some of these operations can be done in delegation mode, by adding the onBehalfOfUserName
(delegator username) or the onBehalfOf
(delegator ID) arguments to the request JSON payload, such as in the following example:
Request payloads:
In this case, the response payload will also contain the onBehalfOf
and onBehalfOfUserName
arguments.
In the case of CancelActionAssignment
and UpdateRequestDataset
operations, the delegation mode is not supported.
clientMutationId
clientMutationId
clientMutationId
is an optional argument that can be used by the requester to identify the execution of an operation. Its value is defined in the input payload (e.g. a UUID). If defined, the same value is returned by the operation.

Known limitations
For file type data parameters, the URL must start with file://
, and the path has to be available to the WorkflowGen server.
Performance optimization
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.
For more information, see the Best practices and troubleshooting guide for node applications on Azure App Service Windows Microsoft article.
