API developer key is invalid

If you see "The API developer key is invalid" in Portant, it almost always means your browser is signed in to more than one Google account at the same time. Here's how to clear it.

Quickest fix: open Portant in an incognito window

Open a private or incognito window in your browser and sign in to Portant from there. Because incognito windows don't carry your existing Google sessions, the right account is used straight away.

If that doesn't work: clear your browser cache

Sometimes the browser holds an old version of the API key. Clearing cookies and cached data fixes this.

Chrome

1. Click the three dots in the top right and choose History.
2. Click Clear browsing data.
3. Tick Cookies and other site data and Cached images and files, then clear.

Firefox

1. Click the three lines in the top right and choose Settings.
2. Go to Privacy & Security and scroll to Cookies and Site Data.
3. Click Clear Data, tick both options, then clear.

Safari

1. Click Safari in the top menu bar and choose Settings.
2. Open the Privacy tab and click Manage Website Data.
3. Click Remove All.

Once your cache is clear, reload Portant and try the action again. If you're still seeing the error, send us a support ticket and we'll take a closer look.
