playwright-oauth-code-capture

To capture an OAuth authorization code in Playwright when localhost redirects fail, register a page.route interception before triggering the flow to read the full redirect URL before the request aborts, enabling extraction of the code parameter.

Your Playwright OAuth flow loses the authorization code because desktop-style redirect_uri=http://localhost requests fail without a local server, aborting the navigation before the code parameter can be read.

Yes, this OAuth code capture method works with Google and GitHub providers, intercepting their desktop-style OAuth flows that use redirect_uri=http://localhost to extract the authorization code for token exchange.

The best way to get an OAuth token from a localhost redirect in automation testing is intercepting the request with Playwright's page.route to capture the URL and extract the code parameter for token exchange.

No, you do not need a local server running to capture OAuth codes during Playwright automation, because page.route interception reads the full redirect URL before the localhost request fails and the code is lost.
