What is the process for obtaining a new token in a Linnworks embedded application?

I decided to share my issue on this platform since the support from Linnworks is virtually non-existent.

My dilemma involves a private embedded app created within Linnworks that showcases orders in spreadsheet format. The app, constructed using Vue.js and axios for data retrieval from Linnworks APIs, works flawlessly except for one aspect - it only displays 100 orders at a time for efficiency purposes.

To address this limitation, I added a "load more orders" button that appends an additional 100 orders to the existing sheet. However, after a period of inactivity, this action triggers a "401 unauthorised error" due to token expiration.

Since the embedded app retains the token in the src attribute of the iframe during initialization, the expired token remains unchanged, leading to authorization issues.

<iframe src="https://example.com/sheet.html?token=9b11e8ff-4791-aca5-b58d-f6da84e996a6"></iframe>

Is there a method to obtain a refreshed token without reloading the entire app?

Answer №1

For tokens, the default Time To Live (TTL) is set to 30 minutes. To ensure your token/session stays active, simply use a basic method such as /api/Main/Ping to poll the API.

Answer №2

After receiving a response from Linnworks, I was able to resolve the issue:

Upon further investigation, it was discovered that the problem stemmed from the pinging of the AuthorizeByApplication call. To prevent the occurrence of a 401 Unauthorised "Token has expired. please re-verify the user" error, it is advised to make the AuthorizeByApplication call when the application is launched and save the response.

Once the session is established, there should be no need to call AuthorizeByApplication again. The token provided in this session has a TTL of 30 minutes. Using this token in subsequent calls will reset the TTL back to 30 minutes. Therefore, as mentioned in the response to your Stackoverflow query, periodically calling "api/Main/Ping" will refresh the 30-minute TTL with minimal impact on your application's performance.

To Prevent Applications From Using Expired Tokens:

  1. When launching the application, invoke AuthorizeByApplication and store the session response.
  2. Maintain the session by invoking "api/Main/Ping" with the stored session token to reset the TTL of the saved session.
  3. Utilize the original saved session token for all application calls.
