Use Gmail account to create a LTX Studio account

Use your Gmail account to create a LTX Studio account if you don’t have one already.

LTX Studio cookie expires after 3 months. You will need to repeat the process described below every 3 months.

Open a Chromium-compatible browser (e.g. Google Chrome, Microsoft Edge or Opera) and navigate to https://app.ltx.studio.

If you are already logged in to your LTX Studio account, make sure to log out. This is an IMPORTANT step, do not skip it.

Login to your LTX Studio account 1 and refresh the page 2.

Once the page is fully loaded, ensure that you’re logged in.

Open Developer Tools by right-clicking on the page and selecting “Inspect Element” or via keyboard shortcuts: Mac Command+Option+I or Windows F12 or Control+Shift+I.

Select Developer Tools » Network 3:

  • Make sure that All or Fetch/XHR is selected 4.
  • Type /me in the filter box 5 and press Enter.
  • Locate the me http call shown on the image above 6, click on that entry.
  • Select the “Headers” tab 7.
  • Locate Request Headers 8 Cookie 9 and copy its entire value 10.
    This is your cookie.

As an example above the cookie:

optimizelyEndUserId=abc9376852143759a8.5293814067427834; x-country-code=CA; successfulLogin=true; lt_refresh_token=XZH3wPmQygrpBuZRXMvGb_ui8LmWVuQ4vx47JBkF82-xc4edziuGYeT9aNL7-k2v; lt_id=zxcwTYfgHrpxxBbOG3V-K; optimizelySession=2849625738195; lt_token=eyJh…

After the cookie is retrieved, DO NOT LOG OUT from the account and simply close the browser. Logging out will terminate your session and prevent the API from using your cookie.

You MUST close the browser tab containing the session used to retrieve the cookie for the API. If you keep it open, the cookie will be refreshed within the browser and will prevent the API from refreshing your cookie properly, resulting in an email with an error message.

If you want to use the account linked to the API from the browser, ensure that you clear all cookies before opening the ltx.studio website again.

Verify and add account

Select Add Account to complete setup, or Verify to test your cookie first. You should receive response 200 if successful. You can also use POST /accounts directly.
