Workflow applications are used in processes to perform certain activities. You can also create your own custom workflow applications. ### Built-in applications WorkflowGen provides some built-in workflow applications, such as: - [XMLTODATABASE](https://discuss.workflowgen.com/search?q=xmltodatabase%20category%3A23): Export XML data to an SQL database - [GETUSERSFROMDIR](https://discuss.workflowgen.com/t/workflow-application-getusersfromdir-usage/489/1): Query the WorkflowGen directory to retrieve users - [RAISEEXCEPTION](https://discuss.workflowgen.com/t/workflow-application-raiseexception-exception-name-and-exception-message-parameters/478): Trigger an exception on a request action (e.g. cancellation) - [UPDATEPROCESSDATA](https://discuss.workflowgen.com/t/workflow-application-updateprocessdata-usage/475): Update a request data - [GETPROCESSDATA](https://discuss.workflowgen.com/t/workflow-application-getprocessdata-usage/480): Retrieve a request data - [GETFORMDATA](https://discuss.workflowgen.com/t/workflow-application-getformdata-usage/481): Retrieve the form field values of a specific request. - [COMPLETEACTION](https://discuss.workflowgen.com/t/workflow-application-completeaction-usage/476): Complete a request action - [MERGEFORM](https://discuss.workflowgen.com/t/workflow-application-mergeform-usage/487): Merge multiple form data - [CANCELREQUEST](https://discuss.workflowgen.com/t/workflow-application-cancelrequest-usage/479): Cancel an ongoing request - [COPYDATA](https://discuss.workflowgen.com/t/workflow-application-mergeform-usage/487): Copy data from a parameter to a different data - [SENDMESSAGE](https://discuss.workflowgen.com/t/workflow-application-sendmessage-usage/490/1): Send SMS notifications from within a form - [SENDHTTPPOST](https://discuss.workflowgen.com/t/workflow-application-sendhttppost-usage/1508): Create outgoing webhooks to external systems - [RESTAPICLIENT](https://discuss.workflowgen.com/t/workflow-application-restapiclient-usage/1509): Call REST API endpoints to exchange information with other applications through HTTP requests - [EXECSQL](https://discuss.workflowgen.com/t/workflow-application-execsql-usage/): Execute one or multiple SQL queries in a process - [JSONTODATA](https://discuss.workflowgen.com/t/workflow-application-jsontodata-usage/2273): Parse JSON content into process data - [DOCUSIGNSEND & DOCUSIGNCHECK](https://discuss.workflowgen.com/t/workflow-applications-docusignsend-docusigncheck-usage/1933): Send one or more documents to DocuSign for electronic signature, and check the status of an envelope and download its associated file - [ADOBESIGNSEND & ADOBESIGNCHECK](https://discuss.workflowgen.com/t/workflow-applications-adobesignsend-adobesigncheck-usage/1934): Send one or multiple documents to Adobe Sign for electronic signature, and verify the status of an agreement and download its associated file - [DOCAPOSTESEND & DOCAPOSTECHECK](https://discuss.workflowgen.com/t/workflow-applications-docapostesend-docapostecheck-usage/1935): Send one or more documents to Docaposte for electronic signature, and check the status of a transaction and download the associated files - [YOUSIGNSEND & YOUSIGNCHECK](https://discuss.workflowgen.com/t/workflow-applications-yousignsend-yousigncheck-usage/2215): Send one or more documents to Yousign for electronic signature, and verify the status of an agreement and download its associated file - [OPENAITRANSCRIPTION](https://discuss.workflowgen.com/t/workflow-application-openaitranscription-usage/2225): Interact with an OpenAI audio model to transcribe an audio file - [OPENAICHAT](https://discuss.workflowgen.com/t/workflow-application-openaichat-usage/): Interact with an OpenAI chat model - [OPENAIADDMESSAGE](https://discuss.workflowgen.com/t/workflow-application-openaiaddmessage-usage/2260): Update the message history of a conversation to add user or tool interactions, including directly from a sub-process - [COUNTER](https://discuss.workflowgen.com/t/workflow-application-counter-usage/2261): Manipulate a counter in a loop - [GETAGENTTOOLDATA](https://discuss.workflowgen.com/t/workflow-application-getagenttooldata-usage/2262): Extract information from a tool that can be provided by an application such as [OPENAICHAT](https://discuss.workflowgen.com/t/workflow-application-openaichat-usage/2226) - [GETAGENTTOOL](https://discuss.workflowgen.com/t/workflow-application-getagenttool-usage/2263): Extract a tool and its information from a list of tools that can be provided by an application such as [OPENAICHAT](https://discuss.workflowgen.com/t/workflow-application-openaichat-usage/2226) ### .NET Assembly The assembly workflow application type lets you declare a .NET class method as a workflow application. This is the fastest way to develop custom workflow applications (compared to web services). (See the [Workflow applications](https://advantys.gitbooks.io/workflowgen-integration-guide/content/workflow-applications.html) section in the [WorkflowGen Integration Guide](https://advantys.gitbooks.io/workflowgen-integration-guide/content/) for detailed instructions on .NET workflow application development.) Execution performance is also better because WorkflowGen directly instantiates the assembly without network communication and without Web Service authentication. You can create a method with standard parameters or by using a single workflow context parameter (`WFGEN_CONTEXT`) for more flexibility. [Workflow Application: Assembly: Use a .NET Class method as a Workflow Application](https://discuss.workflowgen.com/t/workflow-application-assembly-use-a-net-class-method-as-a-workflow-application/468) [Workflow Application: Assembly: Use an assembly method with a workflow context parameter for more flexibility](https://discuss.workflowgen.com/t/workflow-application-assembly-use-an-assembly-method-with-a-workflow-context-parameter-for-more-flexibility/483) ### Web Services You can create Web Service workflow applications. WorkflowGen supports SOAP Web Services and WCF services. #### Example of a Web Service (ASMX) declaration ![](https://canada1.discourse-cdn.com/flex030/uploads/workflowgen/original/1X/4861a905c2076c0b1adf8a6fea6245e51edd22df.png) #### Web Services parameters ![](https://canada1.discourse-cdn.com/flex030/uploads/workflowgen/original/1X/1f0d323cc0f37416cc7de276c3a9c5239558740c.png) [Workflow Application: WCF Service compared to ASMX Web Service](https://discuss.workflowgen.com/t/workflow-application-wcf-service-compared-to-asmx-web-service/477)
