Integration

Integration Scope

The eChallan service is used to generate e-challans / bill for all miscellaneous / adhoc services which citizens avail from ULBs.

Integration Benefits

Can perform service-specific business logic without impacting the other module.
Provides the capability of capturing the unique identifier of the entity for which the challan is generated.
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.
Allow employee to update / cancel challan

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 status of application based on workflow.
