In the future, if we want to expose the application to citizen then it can be done easily.
Workflow or Service-specific workflow can be enabled at the challan service level at any time without changing the design.

Steps to Integration

To integrate, host of echallan-services module should be overwritten in helm chart.
echallan-services/eChallan/v1/_create should be added as the create endpoint for creating eChallan in the system
echallan-services/eChallan/v1/_search should be added as the search endpoint. This method handles all requests to search existing records depending on different search criteria
echallan-services/eChallan/v1/_update should be added as the update endpoint. This method is used to update fields in existing records or to update the status of the application based on workflow.
