Please check out https://test-discourse.kore.ai/t/getting-started-with-widget-sdk-v7-2-onwards/1154/2

or https://test-discourse.kore.ai/t/facing-issue-while-integrating-bot-with-web-mobile-client-channel/521/12

Please note - JWT hosting needs to be done at dev/ customer’s end.
This may be helpful in setting it up.

In case you want to obfuscate your client id and secret and not expose to users, you can refer this update on below thread. Required c# code instead of Js functions for Kore bot Implementation

hi can you help me to get any jwt url so that i can check as when i open the link http://localhost:3000/api/users/sts it is not providing any output?

SDKApp is a node program/ service. Have you done npm install and installed all dependencies; node startServer.js (as described in step 25 and 26 of https://developer.kore.ai/docs/bots/sdks/kore-ai-web-sdk-tutorial/#Installing_and_Running_the_Koreai_Web_SDK The links already shared should have taken you to this page too)?
I see you are using 8080 to server index.html but your jwt is probably on 3030, while that does not make any difference, just ensure local jwt is running.
You will not be able to open the link http://localhost:3000/api/users/sts as is. It is not a supposed to be a get method call and needs a payload.
Please go through all the links presented and do step by step. Use the documentation link in point 1.

is webSDK or SDKApp both are different we have to follow both or just i m doing it with only webSDK is correct? Sorry for this stupid question…

@raj.sharma9

WebSDK consumes JWT service.
JWT gives -

A Demo JWT service
A demo local server to serve the content of index.html.

Hope this helps.

Getting this error now

@raj.sharma9
Can you show the network tab (instead of vonsole) what is the response for jwtgrant?
Ensure you have published your bot.

raj.sharma9 · February 4, 2021, 5:53am

here is the network tab saying Client error

swagata.sengupta · February 5, 2021, 3:29am

What this means is that the client id and secret you are using are not the ones from the app that is published (assuming) with the bot’s web/mobile channel.
You will need to ensure same client id, secret, botid combination is used and it is in sync with bot’s channel and web-sdk. Also publish is important.

It’s really a nice and helpful dissertation writing services piece of information. I’m glad that you shared this helpful info with us.
