Intastellar Accounts is the identity layer for Intastellar products. These guides explain how to add web sign-in so people can use the same account across Intastellar services.

inta.dev hosts this documentation, search, and may offer signed-in tools (such as developer credentials) depending on the product—implementation details stay in your own deployment docs.

What you can build

In your own sites and apps:

1. Use the React SDK (integrating React and JavaScript) or plain HTML, CSS, and JS (Plain HTML, CSS, and JavaScript) for browser sign-in, or
2. Implement an OAuth-style authorization code flow (often with PKCE) for custom stacks—see the web guides below.

Guides (Sign in — Web)

• Intastellar Sign-In — React SDK and plain JavaScript — React patterns with placeholder examples; links to npm.
• Plain HTML, CSS, and JavaScript — migrated from developers.intastellarsolutions.com/…/js-docs: static sites, script tags, optional bundler appendix with IntastellarAPI.
• Getting started — register a client, choose public vs confidential, plan redirects and sessions.
• Authorization code flow — auth URL, state, PKCE, and code exchange (custom integrations).
• Redirect URIs and callbacks — allowed URLs, validation, and common mistakes.
• Sessions, cookies, and tokens — your origin, SDK, and your session model.
• SPAs and JavaScript clients — PKCE and SDK path.
• Server-side (confidential) clients — exchanging the code on your backend.
• Logout, errors, and troubleshooting — ending sessions and typical issues.

Legacy developer URL

Older links may point at developers.intastellarsolutions.com (including …/identity/sign-in/web/docs/js-docs). Prefer HTTPS redirects to inta.dev; the plain HTML / JavaScript guide above is the home for that content. Update OAuth client redirect / login URIs so they match the live URLs you serve.
