How to programatically create Application link and configure it programatically using APIs

[aprakash6904]

I am using the below json to create an application link,

{
"applicationLink": {
"typeId": "generic",
"name": "myapp",
"displayUrl": "https://jira-server.msteams-atlassian.com",
"rpcUrl": "https://jira-server.msteams-atlassian.com",
"isPrimary": false,
"isSystem": true
},
"username": "admin",
"password": "admin",
"customRpcURL": false,
"rpcUrl": "",
"createTwoWayLink": false,
"configFormValues": {
"trustEachOther": false,
"shareUserbase": false
}
}

Application link is created- OK

But, when I try to add the further configuration of oauth authentication using json, it is not working. Error 404/500/consumer key not found, kindly suggest

{
"applicationLink": {
"typeId": "generic",
"name": "Microsoft Teams",
"displayUrl": "https://jira-server.msteams-atlassian.com",
"rpcUrl": "https://jira-server.msteams-atlassian.com",
"isPrimary": false,
"isSystem": true
},
"consumerKey": "OauthKey",
"consumerName": "MicrosoftTeamsIntegration",
"publicKey": "xyz"
"customRpcURL": false,
"rpcUrl": "",
"createTwoWayLink": false,
"configFormValues": {
"trustEachOther": false,
"shareUserbase": false
}
}

Kindly let me know the json format for complete configuration? Also how to programmatically configure application link using correct json
