Authentication

You must issue App Secret before issuing jwt token to use channel APIs.

Follow below sequences from App config - Authentication & Authorization in Channel Development Portal.

1. Issuing App Secret

Click Issue button located on the top of the App Settings page. Be careful not to expose issued secret. Previously issued secret will be invalidated if you refresh it.

2. Registering App Permissions

You must select the Functions you want to use on each sections: Channel, User, Manager. See here for details on each function.

Permissions you selected on User and Manager sections will be included in tokens passed to WAM.

Permissions you selected on Channel section can be issued with token by following process (3).

3. Exchanging App Secret with Token through Native Function

Once you have issued App secret, you can exchange it with jwt token using Native Function

IssueToken

• Request

  JSON

  {
  	"method": "issueToken",
  	"params": {
  		"secret": ""
  		"channelId": ""
  	}
  }
  

  fields	notes	required	type
  secret	App Secret	true	string
  channelId	channelId if you want to specify chanenl	false	string

  If you do not specify channelId , app token will be issued by default. It includes permissions of following Native Functions.

  • registerCommands - registers commands to app. For detailed explanations, please refer Command documentations.

    If you specify channelId, you can issue token including permissions you selected on Channel section on step (2). In this case, make sure your app is installed on specified channel.

• Response

  JSON

  {
  	"accessToken": "{access-token}",
  	"refreshToken": "{refresh-token}",
  	"expiresIn": 1800,
  }
  

  fields	notes	required	type
  refreshToken	refreshToken	true	string
  accessToken	accessToken	false	string
  expiresIn	seconds	true	int64

  Your token is located on accessToken . See below for usage of refreshToken.

refreshToken

• Request

  JSON

  {
  	"method": "refreshToken",
  	"params": {
  		"refreshToken": "{refresh-token}"
  	}
  }
  

  params	notes
  refreshToken	refreshToken you got on above step

• Response

  JSON

  {
  	"accessToken": "{access-token}",
  	"refreshToken": "{refresh-token}",
  	"expiresIn": 1800,
  }
  

4. Using jwt Token

You can use jwt tokens on x-access-token http header when using Native Functions or Functions.

Example using x-access-token on Function calling)

PUT app-store-api.channel.io/general/v1/native/fucntions
x-access-token: "{token}"
...

{
	"method": "writeUserChatMessage"
	"params": { ... }
}
