Telegram bot for access to the online course
223 USD Technical task: Telegram bot for access to the online course:
1. Purpose
Create a Telegram bot that functions as a "lock" for the course:
• access is granted only after successful payment on the website;
• the user receives video lessons and notes without the ability to forward/download;
• access is automatically closed after 90 days;
• the bot reminds about the end of access and offers to pay for an extension;
• there is a Help section for technical support (without feedback on the course content).
2. Platform and environment
• Messenger: Telegram.
• Time zone: Europe/Kyiv.
• Interface language: Ukrainian (possibility to add English in the future).
• Payment: through the website (landing) with MonoPay integration.
3. Payment and access logic
1. The user makes a payment on the website (MonoPay).
2. After confirming payment_success on the backend:
• creates a one-time redeem-token (24–32 characters, valid for 14 days);
• generates a short code (6 digits, valid for 14 days);
• sends to the user:
• a success page with a button "Open access in Telegram" (link with token);
• transactional email with a link and 6-digit code.
3. Activation options in the bot:
• The user follows the link → the bot reads start=<redeem_token>, checks on the backend → opens access.
• If the user starts the bot without a link → the bot asks for the 6-digit code from the email → checks on the backend → opens access.
• The bot must be linked to the landing: after successful payment, the user automatically receives a link to the bot (on the success page and in the email) to activate access.
• Access is granted for 90 days.
4. Automatic messages
• Day 0: "Payment received ✅ Access opened until [date]. Start with Lesson 1?"
• Day 75 and 85: reminder "Access will end on [date]. Extend for 90 days?" + button.
• Day 90: "Access completed. You can extend for another 90 days" + button.
• Day 97 (optional): repeat offer to extend access.
5. Content
• Video lessons and notes are stored in Telegram (via file_id).
• All messages are sent with the parameter protect_content=true (to prohibit forwarding/saving).
• Videos — with supports_streaming=true.
• Notes — in PDF format (sendDocument, also with protect_content=true).
• Important: screen recording protection is not possible — this is a platform limitation.
6. Bot menu
• My course → list of modules and lessons.
• Notes → list of PDFs.
• Extend access → transition to the payment page.
• Help → form for contacting technical support.
7. Help (technical support)
• The user selects a topic → describes the problem → can attach a screenshot.
• The bot automatically adds technical data (user_id, platform).
• The request goes to a private admin chat in Telegram with buttons: "Reply", "Close".
• Auto-reply to the user: "Request №[ID] received. We will respond within 24 hours (10:00–18:00 Kyiv time)."
8. Admin functions
• View users, access status, expiration dates.
• Linking email ↔️ telegram_user_id.
• Manual granting of access, closing access, sending an offer for extension.
• Logging all events (payments, accesses, requests).
9. Database (structure)
• users: id, telegram_user_id, email, created_at
• orders: id, email, amount, status, paid_at
• redeem_tokens: id, order_id, token_hash, expires_at, used_at
• short_codes: id, order_id, code_hash, expires_at, used_at
• access: user_id, access_from, access_to, status
• lessons: id, module_no, lesson_no, title, video_file_id, pdf_file_id
• tickets: id, user_id, topic, text, attachments[], status, created_at, resolved_at
10. Security
• redeem tokens and codes are stored as hashes.
• Each token/code is one-time.
• MonoPay webhooks are verified by signature.
• Limits on request frequency (protection against abuse).
11. Test cases
1. Payment → receiving a link → activating access.
2. Payment → receiving a code → activation via code.
3. Used or expired token/code → denial.
4. Reminder on day 75/85 → extension button.
5. Closing access on day 90 → extension offer.
6. Payment for extension → extending access for another 90 days.
7. Creating a request in Help → message to admin → response to user.
12. Launch checklist
1. Set up MonoPay (merchant, webhooks).
2. Implement backend for:
• processing payment_success;
• generating tokens and codes;
• validating tokens/codes;
• managing accesses;
• sending reminders.
3. Implement the bot:
• /start with token;
• /start without token → request code;
• menu (Course / Notes / Extend / Help);
• sending lessons with protection.
4. Integrate email distribution (sending instructions after payment).
5. Upload videos and PDFs to the bot → save file_id.
6. Set up admin chat for Help.
7. Test scenarios (payment, activation, extension, Help).
Please include examples of completed work, cost, and timelines for this project in your response.

Client's review of cooperation with Danylo I.
Telegram bot for access to the online courseI am very satisfied with the collaboration with Danil. He created a bot for the training course - everything was done strictly according to the technical specifications - neatly, functionally, and stably. He regularly kept in touch, answered questions, showed initiative, and proposed solutions that turned out to be even better than the initial ideas. He helped with connecting additional services and integration on the website. Responsible, professional, attentive to details, and works until the desired result is achieved. I sincerely recommend him for collaboration.

Hello.
I have experience with all the points from the technical specifications.
Preliminarily regarding the timeline - it will take a week for development. Then testing/fixes + about 3 days.
The question about the landing page is open - do you already have it? Or will it need to be designed, etc.?
I suggest discussing everything else in private.
I also commit to monitoring the bot's work for two weeks, fixing errors (if they arise), etc.
