Adding Applications

Adding Applications using the Console

In addition to the written instructions below, a video with instructions for adding an application is available on The Things Industries youtube channel.

Go to Applications in the top menu, and click + Add Application to reach the application registration page. Fill the application ID. The other fields are optional.

Click Create Application to create the application.

Your application will be created and you will be redirected to the application overview page of your newly created application.

Adding Applications using the CLI

Create the first application:

APP_ID="app1"
USER_ID="admin"
ttn-lw-cli applications create $APP_ID --user-id $USER_ID

This creates an application app1 with the admin user as collaborator. Make sure to modify user parameters according to your setup.

Adding Applications using the HTTP (REST) API

Example

To create an application my-test-app on thethings.example.com, first create a JSON file named req.json in the same folder with the following example contents.

{
  "application": {
    "ids": {
      "application_id": "my-test-app"
    },
    "name": "My Test Application",
    "description": "Application for my test devices",
    "network_server_address": "thethings.example.com",
    "application_server_address": "thethings.example.com",
    "join_server_address": "thethings.example.com"
  }
}

The request using cURL is as follows.

 curl -X POST -H "Content-Type: application/json" -H "Authorization: Bearer $API_KEY" \
-d @./req.json \
 https://thethings.example.com/api/v3/users/testuser/applications
{"ids":{"application_id":"my-test-app"},"created_at":"2024-01-10T09:13:34.817772Z","updated_at":"2024-01-10T09:13:34.817773Z","name":"My Test Application","description":"Application for my test devices","administrative_contact":{"user_ids":{"user_id":"testuser"}},"technical_contact":{"user_ids":{"user_id":"testuser"}},"network_server_address":"thethings.example.com","application_server_address":"thethings.example.com","join_server_address":"thethings.example.com"}

To create an API key for your application, navigate to API Keys on the left hand menu of your application’s settings and select Add API Key.

Enter a Name for your key, set the Expiry date, select rights that you want to grant and then press Create API Key.

You will see a screen that shows your newly created API Key. You now can copy it in your clipboard by pressing the copy button. After saving the key in a safe place, press I have copied the key. You will not be able to see this key again in the future, and if you lose it, you can create a new one by following this same procedure.

To create an API key for your application with a Delete application right:

API_KEY_NAME="API key for deleting my application"
ttn-lw-cli applications api-keys create \
  --name $API_KEY_NAME \
  --application-id $APP_ID \
  --right-application-delete

The CLI will return an API key such as NNSXS.RLA7AGGMD5ZHBH.... This API key has only delete rights and can therefore only be used for deleting this application. Make sure to copy the key and save it in a safe place. You will not be able to see this key again in the future, and if you lose it, you can create a new one by following this same procedure.

See the CLI Reference for details on managing application API keys using the CLI.
