Back to Templates
clients kept booking meetings during my prayer times. i'd either miss a prayer or scramble to reschedule. the problem wasn't the clients — it was that my calendar had no blocked windows for salah. i needed a way to block those times every day, automatically, without thinking about it.
what this does
i built this so i can send /salah to my Telegram bot and it instantly fetches today's prayer times from IslamicAPI (using the Egyptian General Authority of Survey method for Cairo), calculates a realistic time window for each prayer, blocks all five prayers directly in Google Calendar, logs everything to a Google Sheet, then sends me a confirmation message on Telegram with the exact time windows. prayer times shift daily — this accounts for that automatically.
what's inside
- Telegram Trigger — listens for incoming messages from the bot
- Validate the Sender — blocks anyone who isn't me from running this
- Check if it's Text — filters out non-text messages like stickers or photos
- Check for Triggers — only proceeds if the message is /salah
- Send an Action — sends a typing indicator while the workflow runs
- Get Prayer Times — fetches today's prayer times via IslamicAPI
- Map Prayer Data — extracts and formats the raw API response
- Code in JavaScript — calculates start and end windows per prayer
- Book for Fajr / Dhuhr / Asr / Maghrib / Isha — creates five Google Calendar events
- Map Outputs — bundles all calendar IDs and times into one object
- Store Prayer Bookings — appends a row to Google Sheets for tracking
- Send the Message — sends a formatted confirmation back to me on Telegram
- Error Trigger — catches failures and logs them to a separate sheet
APIs used
- IslamicAPI — fetches today's accurate prayer times by coordinates
- Google Calendar — creates and holds the five prayer block events
- Google Sheets — logs each booking run with full timestamps and event IDs
- Telegram Bot API — receives the /salah command and sends the confirmation
estimated cost per run
free — IslamicAPI is free forever, Google and Telegram APIs have no per-call cost at this usage level.
