# WhatsApp Integration > Log travel expenses from a WhatsApp chat. Send a photo, a PDF, a voice note, or just type the amount — it lands in your trip, categorized. Start before you install the app. Source: https://spentrip.app/features/whatsapp-integration [Open WhatsApp](/whatsapp/) ## Why WhatsApp? ### Zero Friction You're already in the app. Logging an expense is one more message in a thread you had open anyway. ### Four Ways In Type it, photograph it, forward the PDF, or say it out loud. The same AI handles all four. ### Works Offline From the App No Spentrip account needed to begin. Start in the chat, claim the account later, keep everything you logged. ### Straight Into the Right Trip Set a default with /trip, or route a single expense with #trip:Rome2026. ## Getting Started Two ways in, depending on where you're starting from. With no app: open [spentrip.app/whatsapp](/whatsapp/), send a message, and you're logging expenses. With the app already installed: **Settings → WhatsApp** gives you a code to send the bot, which links the chat to your existing trips. The [WhatsApp help article](/help/whatsapp.md) covers the commands, the hashtag syntax, and how to disconnect.
