Configuration Details

Creating Master JSON

The new JSON file needs to contain 3 keys as shown in the below code snippet. The new master can be created either State-wise or ULB-wise. Tenant ID and config in the master config file determine this.

  "tenantId": "< TENANT ID >",
  "moduleName": "< MODULE NAME >",
  "< MASTER NAME >": []

Configuring Master Config File

The master config file is structured as below. Each key in the master config is a module and each key in the module is a master.


Each master contains the following data and the keys are self-explanatory

    "masterName": "<>",
    "isStateLevel": true,
    "uniqueKeys": []
