Amazon Cookie Setup

Amazon metadata works out of the box, but if you run into 503 errors or rate limiting, providing a browser session cookie gives Grimmory a way to look like a regular logged-in user. The cookie is optional but recommended for the most reliable results.

Section titled “Get the Cookie from Your Browser”
  1. Open your regional Amazon site (e.g., amazon.com, amazon.co.uk) and sign in
  2. Open your browser’s developer tools (F12, or Cmd+Option+I on Mac)
  3. Switch to the Network tab
  4. Refresh the page so new requests appear
  5. Select Fetch/XHR from the top filters
  6. Click the first request in the list (the main page load)
  7. In the Headers panel, scroll down to Request Headers and find the Cookie field
  8. Copy the entire cookie value

The cookie is a long string containing multiple key-value pairs separated by semicolons. Copy the whole thing.

Paste It into Grimmory

Section titled “Paste It into Grimmory”
  1. Open Settings > Metadata 1
  2. Under Amazon, select your Region from the dropdown
  3. Paste the cookie string into the Cookie field
  4. Click Save

That’s it. Grimmory will include the cookie when fetching metadata from Amazon, which gives access to richer results and avoids rate limits.

Troubleshooting

Section titled “Troubleshooting”
ProblemWhat to check
Still getting 503 errorsThe cookie may have expired. Repeat the process to grab a fresh one. Make sure you’re signed in to Amazon before capturing.
Metadata missing or sparseMake sure the Region dropdown matches the Amazon site you got the cookie from. A cookie from amazon.co.uk won’t work for amazon.com.
Different regions neededIf your library has books from multiple Amazon regions, you’ll need to update the cookie and region when switching. Grimmory stores one cookie at a time.
Cookie seems too shortMake sure you copied the full value from the Cookie request header, not a single Set-Cookie response header. The request cookie is one long combined string.
