Doctolib Auto-Book Appointment n8n with Reduck + Gmail

Auto-book Doctolib appointments every hour—using Reduck + Gmail

This n8n workflow automatically checks Doctolib for free slots with your selected doctors, books the earliest matching appointment, and emails you the confirmation details—so you spend less time searching and more time showing up.

What this workflow does

• Runs hourly (Schedule Trigger) to start a new search.
• Builds doctor search queries from your configuration, generating searches per doctor and across 15-day windows based on what Doctolib shows at once.
• Retrieves available slots via Reduck by running browser automation (since Doctolib has no public API).
• Selects the earliest slot that fits your allowed dates, weekdays, and hours.
• Stops when it finds a suitable slot (or tries again next hour if none match).
• Checks your existing Doctolib appointments for upcoming visits with the doctors you listed—if one is upcoming, it books nothing.
• Books the appointment on Doctolib using the paired Chrome account managed through Reduck.
• Sends you a Gmail confirmation with the appointment time, doctor, and address.

Use cases

• Get matched with the soonest available appointment within your preferred days and hours.
• Ensure you never double-book: the workflow won’t book if you already have an upcoming appointment with the same doctors.
• Reduce manual effort when monitoring France-based Doctolib availability for recurring needs.

Technical details

• Uses n8n nodes including Schedule Trigger, set, code, and `sticky note`.
• Relies on Reduck (via Reduck community node / `reduck-ain8n-nodes-reduck`) to automate Doctolib in a browser.
• Fetches availability and performs booking in a Reduck-managed browser, then emails details through Gmail.
