Prerequisites

Before deleting files, ensure:
  1. Access Permissions: Ensure that the user account used has the necessary access rights for updates or deletions.
  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. File IDs and Document Types: Prepare information for updating or deleting files:
  • fileId: ID of the file to delete.
  • customId: Custom ID associated with the file.
In the example below, we use a fileId generated for a document using Uploading a New Document scenario.
{
  "docs": [
    {
      "customId": "119407",
      "fileId": "c4e6f0b0-b70a-4141-993b-d304f38ec8e2",
      "documentType": "BULK",
      "documentLabel": null,
      "minioPath": "flowx-dev-process-id-119408/119407/466_BULK.pdf",
      "downloadPath": "internal/files/c4e6f0b0-b70a-4141-993b-d304f38ec8e2/download",
      "noOfPages": 2,
      "error": null
    }
  ],
  "error": null
}

​
Configuring the deletion process

To delete files, follow these steps:
  1. Create a process that includes a Send Message Task (Kafka) node and Message Event Receive (Kafka) node:
  • Use the Send Message Task node to send the delete request.
  • Use the Receive Message Task node to receive the delete reply.
  1. Configure the first node (Send Message Task) by adding a Kafka Send Action.
  1. Specify the Kafka topic for sending the delete request.
To identify defined topics in your environment:
  • Navigate to Platform Status > FLOWX Components > document-plugin-mngt and click the eye icon on the right side.
  • In the details screen, expand the KafkaTopicsHealthCheckIndicator line and then details → configuration → topic → file → delete. Here will find the in and out topics for deleting files.
  1. Fill in the request message body.

​
Message request example

Example of a message following the custom integration data model: 
{
  "customId": "119408",
  "fileId": "c4e6f0b0-b70a-4141-993b-d304f38ec8e2"
}
  • fileId: The ID of the file.
  • customId: The custom ID.
  1. Configure the second node (Receive Message Task) by adding a Data stream topic:
The response will be sent to ..out Kafka topic.

​
Receiving the reply

The reply body should contain the following values:
  • customId: The unique identifier for your document (it could be for example the ID of a client)
  • fileId: The ID of the file
  • documentType: The document type
  • error: Any error message in case of an error during the deleting process
