egov-user-chatbot
: For creating user without name validation and logging in user
egov-user
: For searching user
egov-localization
: The chatbot is made such that it will store localization codes and the actual text value will be fetched only at the end. This way we can provide multi-lingual support. Localization service is also used to construct messages from templates. This dependency can be eliminated if you want to pass values instead of localization codes.
egov-filestore
: It is a dependency if you want to send/receive any file. This includes sending PDF/Image files.
egov-url-shortening
: For shortening links sent to the user
egov-mdms-service
: For loading mdms data
egov-location
: For loading locality data
rainmaker-pgr
: For creating/searching PGR complaints
Chatbot service allows citizen to access PGR service through whatsapp. Citizen can provide all details required to create PGR complaint through question and answer method. The service continuosly listen on PGR update Kafka topic and send notifications to users associated with PGR record. On any message from citizen which is forwarded by whatsapp provider, chatbot processes his messages by passing message through various stages ex:- validations, enrichment, transformations etc and at the end sends final response to user by calling endpoint of whatsapp provider.
There are two types of configurations for chatbot states:-
Configuration for each state in chatbot, ex:-
name : pgr.create.locality description : "Locality" nodeType : step optional : false type : text validationRequired : true typeOfValues : FixedSetValues displayOptionsInExternalLink: true message : chatbot.messages.pgrCreateLocality values : class : org.egov.chat.xternal.valuefetch.LocalityValueFetcher params : tenantId : ~pgr.create.tenantId authToken : /user/authToken recipient: /extraInfo/recipient matchAnswerThreshold: 70 errorMessage: chatbot.messages.pgrCreateLocalityError |
Graph adjacency list configuration:- to define flow between chatbot states,ex:-
root,pgr.create.tenantId,pgr.track.end pgr.create.tenantId,pgr.create.locality pgr.create.locality,pgr.create.landmark |

Add configs required for chatbot Service.
Deploy the latest version of chatbot Service.
Add Role-Action mapping for API’s.
The chatbot service is used to communicate with the users, lodge their complaints or provide miscellaneous / adhoc services which citizens avail from ULBs in an interactive way over whatsapp.
Can perform service-specific business logic without impacting the other module.
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 chatbot level at any time without changing the design.
To integrate, host of chatbot module should be overwritten in helm chart.
POST /messages
should be added as the endpoint for receiving user sent message and forward it to chatbot core logic for further processing and sending back response.
GET /messages
should be added as the endpoint for receiving user sent message and forward it to chatbot core logic for further processing and sending back response.

a) POST /messages
Receive user sent message and forward it to chatbot core logic for further processing and sending back response
If the media_type
parameter value is text
then user input would be sent in parameter text
, in other cases where media_type
have some other value ex:- image, location etc, the user input would be sent in parameter media_data
b) GET /messages
Receive user sent message and forward it to chatbot core logic for further processing and sending back response
If the media_type
parameter value is text
then user input would be sent in parameter text
, in other cases where media_type
have some other value ex:- image, location etc, the user input would be sent in parameter media_data
update-pgr-service
: used in update.pgr.service.topic
application property, chatbot listens on this topic to listen for updates on PGR records and then to send notifications to user.
The service uses consumers for internal processing also between different stages.
send-message-localized
: chatbot sends data to this topic for telemetry indexing and for internal processing.
The service uses producers for internal processing also between different stages.
