OAuth Authorization URL Builder

Never paste a client secret, access token or refresh token. The tool does not perform login, token exchange, redirect registration or provider validation.

Do not paste a client secret, access token or refresh token. This page builds Authorization Code requests only. PKCE is generated locally; keep the verifier bound to the same client transaction. It does not perform login or token exchange.

URL workflow

Inspect structure first, then normalize or edit only the part you mean to change. Browser-local tools avoid sending pasted links to a remote parser.

ParseSeparate scheme, authority, path, query and fragment.

Normalize deliberatelyChoose cleanup rules instead of assuming one universal canonical URL.

Edit / expandWork with query rows, relative references or URI templates structurally.

Compare / batchAudit repeated params or many URLs without fetching them.

Verify destination contextSyntax tools cannot prove a URL exists, redirects safely or is authorized.

v11.03 URL tools are string-processing utilities. They do not crawl destinations, follow redirects, resolve DNS, check TLS, or verify OAuth provider registration.

Explicit URL-tool scope

OAuth client IDs are public identifiers; client secrets and tokens are not authorization-URL parameters and should never be pasted here. The builder uses Authorization Code flow and can generate transaction-local PKCE S256 material.

Browser-local processing

Build the browser redirect URL for OAuth 2.0 / OpenID Connect authorization requests from public parameters. No destination URL is fetched by this v11.03 workflow.
