Reusable Angular-hosted UI for Telegram login.

The app now contains a single standalone page based on the extracted dialog design. It preserves the same visual states and the same state-switcher behavior from the provided HTML:

The app now boots directly into the live `userauth` flow instead of a demo dialog. On load it:

- checks `GET /userauth/session`
|

- `loading`

- creates a QR session with `POST /userauth/qr/create`
|

- `checking`
|
- polls `GET /userauth/qr/poll?token=...` every 5 seconds

# Telegram UserAuth Backend Contract
|
||||||
|
|
||||||
|
This document extracts the existing Telegram login flow into a repo-neutral contract for reuse in other projects.
|
||||||
|
|
||||||
|
The UI behavior, payloads, polling cadence, and session model stay the same. Only route names and cookie naming are generalized.
|
||||||
|
|
||||||
|

|
## Flow Summary
|
||||||
|
|
||||||
|
There are two supported flows.
|
||||||
|
|
||||||
|
### 1. Direct login from button
|
||||||
|
|
||||||
|
1. Frontend opens `https://t.me/{botUsername}?start=auth_{callbackUrl}`.
|
||||||
|
2. Telegram bot creates a session and sends the user a login button.
|
||||||
|
3. The button points to `GET /userauth/telegram/callback?token={sessionId}`.
|
||||||
|
4. Backend sets `userauth_session` cookie and redirects back to the storefront.
|
||||||
|
5. Frontend calls `GET /userauth/session` and becomes authenticated.
|
||||||
|
|
||||||
|
### 2. QR login from desktop
|
||||||
|
|
||||||
|
1. Frontend opens dialog.
|
||||||
|
2. Frontend calls `POST /userauth/qr/create`.
|
||||||
|
3. Backend returns `{ token, url }` where `url` is a Telegram deep link.
|
||||||
|
4. Frontend renders a QR from that URL.
|
||||||
|
5. User scans QR and bot calls `POST /userauth/qr/confirm`.
|
||||||
|
6. Frontend polls `GET /userauth/qr/poll?token=...` every 3 seconds.
|
||||||
|
7. When status becomes `confirmed`, backend returns session payload and sets the cookie.
|
||||||
|
8. Frontend syncs local cart using `POST /usersession/{sessionId}`.
|
||||||
|
|
||||||
|
## Session Shape
|
||||||
|
|
||||||
|
The frontend expects this exact response shape for the authenticated session.
|
||||||
|
|
||||||
|
```json
|
||||||
|
{
|
||||||
|
"sessionId": "550e8400-e29b-41d4-a716-446655440000",
|
||||||
|
"telegramUserId": 123456789,
|
||||||
|
"username": "ivan_petrov",
|
||||||
|
"displayName": "Ivan Petrov",
|
||||||
|
"active": true,
|
||||||
|
"expiresAt": "2026-05-21T14:30:00Z"
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
| Field | Type | Required | Notes |
|
||||||
|
|---|---|---|---|
|
||||||
|
| `sessionId` | string | yes | Session identifier used in cart sync |
|
||||||
|
| `telegramUserId` | number | yes | Telegram user ID |
|
||||||
|
| `username` | string or null | no | Telegram username |
|
||||||
|
| `displayName` | string | yes | User-facing full name |
|
||||||
|
| `active` | boolean | yes | `false` means expired session |
|
||||||
|
| `expiresAt` | ISO 8601 string | yes | Used by frontend refresh scheduling |
|
||||||
|
|
||||||
|
Recommended TTL:
|
||||||
|
|
||||||
|
- Session TTL: 24 hours
|
||||||
|
- QR token TTL: 5 minutes
|
||||||
|
|
||||||
|
## HTTP Contract
|
||||||
|
|
||||||
|
### `POST /userauth/qr/create`
|
||||||
|
|
||||||
|
Creates a one-time QR login token when the dialog opens.
|
||||||
|
|
||||||
|
Request body:
|
||||||
|
|
||||||
|
```json
|
||||||
|
{}
|
||||||
|
```
|
||||||
|
|
||||||
|
Response `200`:
|
||||||
|
|
||||||
|
```json
|
||||||
|
{
|
||||||
|
"token": "dG9rZW4tYWJjMTIz",
|
||||||
|
"url": "https://t.me/userauth_bot?start=login_dG9rZW4tYWJjMTIz"
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
Requirements:
|
||||||
|
|
||||||
|
- Generate a cryptographically secure token.
|
||||||
|
- Save token with status `pending`.
|
||||||
|
- Return a Telegram deep link in `url`.
|
||||||
|
- Rate limit to 5 requests per minute per IP.
|
||||||
|
|
||||||
|
### `GET /userauth/qr/poll?token={token}`
|
||||||
|
|
||||||
|
Called every 3 seconds until confirmation or expiration.
|
||||||
|
|
||||||
|
Possible responses:
|
||||||
|
|
||||||
|
Pending:
|
||||||
|
|
||||||
|
```json
|
||||||
|
{ "status": "pending" }
|
||||||
|
```
|
||||||
|
|
||||||
|
Confirmed:
|
||||||
|
|
||||||
|
```json
|
||||||
|
{
|
||||||
|
"status": "confirmed",
|
||||||
|
"session": {
|
||||||
|
"sessionId": "550e8400-e29b-41d4-a716-446655440000",
|
||||||
|
"telegramUserId": 123456789,
|
||||||
|
"username": "ivan_petrov",
|
||||||
|
"displayName": "Ivan Petrov",
|
||||||
|
"active": true,
|
||||||
|
"expiresAt": "2026-05-21T14:30:00Z"
|
||||||
|
}
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
Expired:
|
||||||
|
|
||||||
|
```json
|
||||||
|
{ "status": "expired" }
|
||||||
|
```
|
||||||
|
|
||||||
|
Behavior:
|
||||||
|
|
||||||
|
- If confirmed, set cookie `userauth_session` in the response.
|
||||||
|
- Delete or invalidate the QR token after the first successful confirmed poll.
|
||||||
|
- If token is unknown or expired, return `status: "expired"`.
|
||||||
|
|
||||||
|
### `POST /userauth/qr/confirm`
|
||||||
|
|
||||||
|
Internal endpoint called by the Telegram bot after the user scans the QR code.
|
||||||
|
|
||||||
|
Required header:
|
||||||
|
|
||||||
|
```text
|
||||||
|
X-Bot-Secret: <shared secret between bot and backend>
|
||||||
|
```
|
||||||
|
|
||||||
|
Request body:
|
||||||
|
|
||||||
|
```json
|
||||||
|
{
|
||||||
|
"token": "dG9rZW4tYWJjMTIz",
|
||||||
|
"telegram_user": {
|
||||||
|
"id": 123456789,
|
||||||
|
"first_name": "Ivan",
|
||||||
|
"last_name": "Petrov",
|
||||||
|
"username": "ivan_petrov"
|
||||||
|
}
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
Response `200`:
|
||||||
|
|
||||||
|
```json
|
||||||
|
{ "status": "ok" }
|
||||||
|
```
|
||||||
|
|
||||||
|
Behavior:
|
||||||
|
|
||||||
|
- Validate `X-Bot-Secret`.
|
||||||
|
- Validate token exists and is still `pending`.
|
||||||
|
- Create a user session.
|
||||||
|
- Store session ID on the QR token.
|
||||||
|
- Mark QR token as `confirmed`.
|
||||||
|
|
||||||
|
### `GET /userauth/session`
|
||||||
|
|
||||||
|
Returns the currently active session based on the cookie.
|
||||||
|
|
||||||
|
Frontend behavior depends on this endpoint in two places:
|
||||||
|
|
||||||
|
- initial auth check on app startup
|
||||||
|
- fallback polling if QR token creation fails
|
||||||
|
|
||||||
|
Response `200`:
|
||||||
|
|
||||||
|
```json
|
||||||
|
{
|
||||||
|
"sessionId": "550e8400-e29b-41d4-a716-446655440000",
|
||||||
|
"telegramUserId": 123456789,
|
||||||
|
"username": "ivan_petrov",
|
||||||
|
"displayName": "Ivan Petrov",
|
||||||
|
"active": true,
|
||||||
|
"expiresAt": "2026-05-21T14:30:00Z"
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
Error handling:
|
||||||
|
|
||||||
|
- Any non-200 response is treated by the frontend as unauthenticated.
|
||||||
|
|
||||||
|
### `GET /userauth/telegram/callback?token={sessionId}`
|
||||||
|
|
||||||
|
Used for direct Telegram login from the primary button flow.
|
||||||
|
|
||||||
|
Behavior:
|
||||||
|
|
||||||
|
- Read the `token` query param.
|
||||||
|
- Resolve it to a valid active session.
|
||||||
|
- Set cookie `userauth_session`.
|
||||||
|
- Redirect user to the storefront URL.
|
||||||
|
|
||||||
|
### `POST /userauth/logout`
|
||||||
|
|
||||||
|
Clears the backend session and expires the cookie.
|
||||||
|
|
||||||
|
Request body:
|
||||||
|
|
||||||
|
```json
|
||||||
|
{}
|
||||||
|
```
|
||||||
|
|
||||||
|
Response `200`:
|
||||||
|
|
||||||
|
```json
|
||||||
|
{ "message": "ok" }
|
||||||
|
```
|
||||||
|
|
||||||
|
### `POST /usersession/{sessionId}`
|
||||||
|
|
||||||
|
Synchronizes local cart immediately after successful login.
|
||||||
|
|
||||||
|
Request body:
|
||||||
|
|
||||||
|
```json
|
||||||
|
[
|
||||||
|
{
|
||||||
|
"itemID": 123,
|
||||||
|
"quantity": 2,
|
||||||
|
"colour": "#ff0000",
|
||||||
|
"size": "XL",
|
||||||
|
"price": 1500
|
||||||
|
}
|
||||||
|
]
|
||||||
|
```
|
||||||
|
|
||||||
|
Notes:
|
||||||
|
|
||||||
|
- This payload is unchanged from the existing implementation.
|
||||||
|
- `price` is already discounted on the frontend side.
|
||||||
|
- The frontend skips the call if cart is empty.
|
||||||
|
|
||||||
|
## Telegram Deep Link Format
|
||||||
|
|
||||||
|
Direct login link format:
|
||||||
|
|
||||||
|
```text
|
||||||
|
https://t.me/{botUsername}?start=auth_{urlEncodedCallbackUrl}
|
||||||
|
```
|
||||||
|
|
||||||
|
QR login link format:
|
||||||
|
|
||||||
|
```text
|
||||||
|
https://t.me/{botUsername}?start=login_{qrToken}
|
||||||
|
```
|
||||||
|
|
||||||
|
Important limit:
|
||||||
|
|
||||||
|
- Telegram limits the `start` payload to 64 characters.
|
||||||
|
- A base64url encoding of 32 random bytes plus `login_` fits safely.
|
||||||
|
|
||||||
|
## Cookie Requirements
|
||||||
|
|
||||||
|
Use these cookie settings for the frontend to work correctly across site and API origins.
|
||||||
|
|
||||||
|
| Property | Value |
|
||||||
|
|---|---|
|
||||||
|
| Name | `userauth_session` |
|
||||||
|
| Path | `/` |
|
||||||
|
| HttpOnly | `true` |
|
||||||
|
| Secure | `true` |
|
||||||
|
| SameSite | `None` |
|
||||||
|
| MaxAge | `86400` |
|
||||||
|
| Domain | your shared parent domain, for example `.example.com` |
|
||||||
|
|
||||||
|
## CORS Requirements
|
||||||
|
|
||||||
|
Because the frontend sends credentials, backend must return an explicit origin.
|
||||||
|
|
||||||
|
Required headers:
|
||||||
|
|
||||||
|
```text
|
||||||
|
Access-Control-Allow-Origin: https://your-frontend.example
|
||||||
|
Access-Control-Allow-Credentials: true
|
||||||
|
Access-Control-Allow-Methods: GET, POST, OPTIONS
|
||||||
|
Access-Control-Allow-Headers: Content-Type
|
||||||
|
```
|
||||||
|
|
||||||
|
Do not use `*` for `Access-Control-Allow-Origin` together with credentials.
|
||||||
|
|
||||||
|
## Frontend Runtime Expectations
|
||||||
|
|
||||||
|
The current dialog behavior is fixed and should be preserved by backend responses.
|
||||||
|
|
||||||
|
- QR polling interval: every 3 seconds
|
||||||
|
- QR expiration on frontend: after 100 checks
|
||||||
|
- If QR creation fails, frontend falls back to direct login URL and session polling
|
||||||
|
- After login, frontend closes the dialog and re-checks session
|
||||||
|
|
||||||
|
## Minimal Backend Checklist
|
||||||
|
|
||||||
|
- Implement all six `userauth` endpoints and the `usersession` sync endpoint.
|
||||||
|
- Store sessions for 24 hours.
|
||||||
|
- Store QR tokens for 5 minutes.
|
||||||
|
- Protect `POST /userauth/qr/confirm` with `X-Bot-Secret`.
|
||||||
|
- Set `userauth_session` cookie on confirmed QR poll and direct callback.
|
||||||
|
- Return the exact session JSON shape.
|
||||||
|
- Support credentialed CORS.
|
||||||
|
|
||||||
|
## Bot Checklist
|
||||||
|
|
||||||
|
- Handle `/start login_{token}` and call `POST /userauth/qr/confirm`.
|
||||||
|
- Handle `/start auth_{callbackUrl}` and provide a button that opens the callback URL.
|
||||||
|
- Send success and expiration messages back to the user.
|
||||||
|
- Share the same `X-Bot-Secret` value with backend.
