Prerequisites

Before retrieving document URLs, ensure:
  1. Access Permissions: Ensure that the user account has the necessary access rights.
  2. Kafka Configuration:
  • Verify Kafka Setup: Ensure proper configuration and accessibility of the Kafka messaging system.
  • Kafka Topics: Understand the Kafka topics used for these operations.
  1. Document Types: Prepare information for updating or deleting files:
  • types: A list of document types.

​
Configuring the getting URLs process

To obtain document URLs, follow these steps:
1

Create the process

Create a process that will contain the following types of nodes:
2

Configure the User Task

Start configuring the User Task node:

​
Node Config

  • Data stream topics: Add the topic where the response will be sent; in this example ai.flowx.updates.document.html.persist.v1 and its key: uploadedDocument.

​
Actions

We will configure the following node actions:
  • Upload File action (“uploadDocument”) will have two child actions:
    • Send Data to User Interface (“uploadDocumentSendToInterface”)
    • Business Rule (“uploadDocumentBR”)
  • Save Data action (“save”)
3

Upload action parameters

Configure the parameters for the Upload Action:
For more details on uploading a document and configuring the file upload child actions, refer to the following sections:
4

Configure the Send Message Task

Next, configure the Send Message Tas (Kafka) node by adding a Kafka Send Action and specifying the ..in Kafka topic to send the request.
Identify defined topics in your environment:
  • Navigate to Platform Status > FlowX Components > document-plugin-mngt and press the eye icon on the right side.
  • In the details screen, expand the KafkaTopicsHealthCheckIndicator line and then details → configuration → topic → document → get. Here will find the in and out topics for getting URLs for documents.
5

Configure the request action

Fill in the body of the request message for the Kafka Send action to send the get URLs request:
Request Message
  • types: A list of document types.

​
Message request example

Example of a message following the custom integration data model:
{
  "types": [
    "119435",
    "119435"
  ]
}
6

Configure the Receive Message Task

Configure the Receive Message Task (Kafka) by adding the ..out kafka topic on which the response will be sent.

​
Receiving the reply

The response body should include the following values:
  • success: A boolean indicating whether the document exists and the URL was generated successfully.
  • fullName: The full name of the document file, including the directory path.
  • fileName: The name of the document file without the extension.
  • fileExtension: The extension of the document file.
  • url: The full download URL for the document.
