Documentation Overview

docstoc

Paste your unpaid invoices. Get the follow-up email already written, in the right tone for how late it is.

docstoc never emails your clients for you — it drafts follow-ups you copy into Gmail, Outlook, or Apple Mail. Tone escalates with days overdue (friendly → firm → direct).

Live URLs

	URL
Marketing	https://docstoc.io/
App (Tool)	https://docstoc.io/app/
Login	https://docstoc.io/app/login
Connector	https://docstoc.io/app/connector
Admin	https://docstoc.io/app/admin
API	https://api.docstoc.io
MCP	https://api.docstoc.io/mcp — read-only tools public; `draft_chase_email` requires session or API key

Worker PUBLIC_APP_URL is https://docstoc.io (magic links, OAuth callbacks, Stripe return URLs, digest links).

Legacy chasa.io / api.chasa.io 301 to docstoc (Pages _middleware.ts + worker redirect). See scripts/oauth-redirect-uris.md for provider console URIs.

Go-live checklist

Attach docstoc.io on Cloudflare Pages project chasa and wait for Active.
www.docstoc.io → apex: handled by apps/web/functions/_middleware.ts (redeploy web).
chasa.io / www.chasa.io → docstoc.io: same middleware.
api.chasa.io → api.docstoc.io: worker middleware in apps/worker/src/lib/legacyHostRedirect.ts.
Register OAuth redirect URIs on api.docstoc.io — see scripts/oauth-redirect-uris.md.
Optional DMARC: ./scripts/dmarc-remove-rua.sh (removes rua= from _dmarc.docstoc.io).
Run ./scripts/go-live-verify.sh.

The order does not matter: browser-facing links are built from the origin the request came in on (see “App origin resolution” below), so pages.dev and chasa.io both keep working whichever is deployed first.

App origin resolution

Magic links, post-login redirects, Stripe return URLs and team invites use the origin the user is actually on, not PUBLIC_APP_URL. The Pages /api proxy forwards it as X-Docstoc-App-Origin, and the worker honours it only if it matches lib/appUrl.ts's allowlist (PUBLIC_APP_URL, docstoc.io, www.docstoc.io, legacy chasa.io hosts, *.pages.dev project/preview hosts, localhost). This keeps preview deploys self-contained and makes the domain cutover zero-downtime.

Requests that arrive without a trusted origin — provider OAuth callbacks hitting api.docstoc.io directly, and the digest cron — still fall back to PUBLIC_APP_URL.

App routes (`/app/*`)

Route	Purpose
`/`	Tool — invoice list, AI drafts, CSV/PDF import, multi-select batch
`/login`	Magic-link login + Cloudflare Turnstile
`/account`	Plan, billing portal, payment link
`/team`	Invite members, roles (Pro+)
`/clients`	Client CRM (Pro+)
`/branding`	Logo + late-fee hint (workspace admin)
`/webhooks`	Outbound webhook URLs (workspace admin)
`/connector`	Cloud storage + QBO/Xero OAuth + API keys
`/admin`	Internal admin dashboard (separate cookie)

All app routes except /login and /admin require a session. Unauthenticated users redirect to /login. SPA analytics require cookie consent (GDPR).

i18n (EN + ES)

Same path as Docracy: lightweight catalogs in apps/web/app/src/lib/i18n/ (no i18next). LocaleProvider + EN|ES switcher on login, sidebar, and More sheet. P1 covers login / shell / welcome; expand catalogs for the rest of the app next. Preference stored as chasa_locale. Marketing HTML stays English until a later pass.
