WhatsApp Flight Price Bot

I need a small automation that lives inside my existing WhatsApp Business number and behaves like a mini travel assistant. The flow is simple: as soon as a user messages the bot, it should ask for departure city, destination and travel date, then head over to wakkago.com, grab the best available fare and send it straight back in the same chat. If wakkago.com returns nothing, the bot must immediately inform the customer that no flights are available—no alternative dates, no extra questions. Once the user supplies the three travel details, the system should automatically continue; there is no additional confirmation step.

A lightweight, well-commented codebase is essential because I’ll be maintaining it after hand-off. Please include clear instructions for connecting the script to my WhatsApp Business API stack and any keys or webhooks required for wakkago.com queries or scraping.

Deliverables
• Source code and dependency list
• Setup guide for WhatsApp Business API integration
• Brief README explaining how the wakkago.com lookup works and where to adjust parameters

I’ll test by supplying a few city pairs and dates. When the chat shows a fare—or the “no flights available” message—I’ll consider the job complete.
