Integration Details
Integration Scope
The eChallan service is used to generate e-challans / bills for all miscellaneous/ad-hoc services which citizens avail from ULBs.
Integration Benefits
Can perform service-specific business logic without impacting the other module.
Allows capturing the unique identifier of the entity for which the challan is generated.
In the future, if we decide to make the application accessible to citizens, it can be done effortlessly.
Workflow or service-specific workflow can be enabled at the challan service level at any time, without the need for any design changes.
Allow employees to update/cancel challan.
Integration Steps
To integrate, you need to overwrite the host of the echallan-services module in the Helm chart.
echallan-services/eChallan/v1/_createshould 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 applications based on workflow.
