Manage Supabase database records with Telegram bot commands

Manage Supabase database with Telegram commands

How it works

1. Receive message — Telegram trigger captures incoming bot messages
2. Validate user — Checks if sender's chat ID is in the authorized list
3. Parse command — Extracts command type (/add, /list, etc.) and parameters
4. Route & execute — Performs the appropriate Supabase operation (INSERT, SELECT, UPDATE, DELETE)
5. Respond — Sends formatted results back to Telegram

Turn your Telegram into a powerful database management interface. This workflow lets you create, read, update, delete, and search records in your Supabase database using simple chat commands — no SQL knowledge required.

Who is this for?

Small business owners, freelancers, and teams who need to manage data on the go without opening dashboards or writing queries. Perfect for inventory tracking, simple CRM, expense logging, or any scenario where you need quick mobile access to your database.

What problem does it solve?

Managing database records typically requires logging into admin panels or writing SQL queries. This workflow eliminates that friction by letting you interact with your data through familiar Telegram messages, from anywhere, on any device.

Benefits

• Mobile database access — Manage your data from anywhere using just your phone
• Zero SQL required — Simple commands replace complex database queries
• Secure by default — Only authorized Telegram users can access your data
• Instant feedback — Get formatted responses confirming every operation
• Fully customizable — Adapt to any table structure with minimal changes

Available commands

Set up steps

1. Create your Telegram bot

• Message @BotFather on Telegram
• Send /newbot and follow the prompts
• Save the API token you receive

2. Get your Telegram chat ID

• Message @userinfobot on Telegram
• It will reply with your chat ID number

3. Create the Supabase table

Run this SQL in your Supabase project's SQL Editor:

CREATE TABLE products (
 id SERIAL PRIMARY KEY,
 name TEXT NOT NULL,
 price DECIMAL(10,2),
 quantity INTEGER DEFAULT 0,
 category TEXT,
 created_at TIMESTAMP DEFAULT NOW()
);

4. Configure the workflow

1. Import the workflow into n8n
2. Add your Telegram Bot credentials (using the API token from step 1)
3. Add your Supabase credentials (Project URL + API Key from Supabase dashboard)
4. Open the "Is Authorized?" node and replace 123456789 with your actual chat ID from step 2
5. Activate the workflow

5. Test it

Send /help to your bot to verify everything works!

Customization

Adding more authorized users

1. Open the "Is Authorized?" node
2. Click "Add condition"

1. Change products to your table name in all Supabase nodes
2. Update the field parsing in the "Parse Command and Parameters" code node
3. Update field mappings in "Supabase Insert Product" and "Prepare Update Data" nodes
4. Adjust the help message in "Send Help Message" node
