How it works Telegram trigger – The workflow starts when a message is sent to the Telegram bot. Authorization check – A Code node verifies if the message comes from an authorized Telegram user ID. Message validation – The workflow checks that: The message contains a photo. The caption starts with /business. Image retrieval – The bot fetches the highest‑quality photo from the message. OCR extraction – The image is sent to Mistral OCR (via HTTP Request) to extract text from the business card. Information extraction – The extracted text is passed to an Information Extractor (powered by an OpenAI chat model) which parses the card and returns structured fields: company_name, first_name, last_name, role, phone, email, website, street_address, city, region, country_code, postal_code. Create Google Contact – A Google Contacts node creates a new contact using the extracted data (addresses, company, emails, phone). Success check – An IF node checks if the contact was created successfully (by verifying resourceName exists). Telegram reply – The bot sends a confirmation message (“Contact successfully added”) or an error message to the user. Set up steps Telegram bot Create a Telegram bot via @BotFather. Add the bot’s API token as a credential in n8n (name: Telegram account Fastewb). User authorization Find your Telegram user ID (e.g., by using @userinfobot). In the Code node, replace XXX with your numeric user ID. Mistral OCR Get an API key from Mistral AI.# Create an HTTP Bearer Auth credential in n8n named Mistral OCR with that key. The node uses https://api.mistral.ai/v1/ocr with a base64‑encoded image. OpenAI chat model Obtain an OpenAI API key. Create an OpenAi API credential in n8n (name: OpenAi account (Eure)). The workflow uses gpt-5.4-mini – ensure this model is available or change it to gpt-4o-mini / gpt-3.5-turbo. Google Contacts Set up Google OAuth2 credentials in n8n with access to Google Contacts API. The node will create contacts under the authenticated Google account. Activate the workflow Save the workflow. Set the Telegram Trigger to Active. In Telegram, send a photo with the caption /business to the bot to test. 👉 Subscribe to my new YouTube channel.
