Most popular Slack + WhatsApp templates
View all →Recover abandoned carts with a delayed WhatsApp nudge
Uses Slack and WhatsApp
Waits an hour after a checkout is abandoned, re-checks the cart against the store API, and sends a WhatsApp template nudge with a recovery link only if it is genuinely still unpaid and above a value floor.
Send WhatsApp order and shipping updates from a verified store webhook
Uses Slack and WhatsApp
Verifies a Shopify order webhook, then sends the customer a WhatsApp message with the order status and tracking link, and logs every send. Unverified payloads and orders without a usable phone number never reach the messaging step.
Send WhatsApp appointment reminders from Google Calendar
Uses Slack and WhatsApp
Reads tomorrow's Google Calendar appointments each morning, extracts each attendee's phone number from the event, and sends an approved WhatsApp template reminder in rate-limited batches, logging every send.
Answer WhatsApp keywords automatically and hand the rest to a human
Uses Slack and WhatsApp
Matches inbound WhatsApp messages against three keyword rules and answers them instantly. Anything else is handed to a human in Slack with the customer's original wording, and every message is logged so the rules can be improved from evidence.
Verify a Razorpay payment webhook and receipt the customer on WhatsApp
Uses Slack and WhatsApp
Verifies a Razorpay webhook's HMAC signature over the raw body, records the payment in PostgreSQL with an idempotent insert, and sends the customer a WhatsApp receipt carrying the payment reference. Unverified payloads are refused outright.
Capture WhatsApp enquiries into Airtable as leads
Uses Slack and WhatsApp
Turns WhatsApp enquiries into Airtable leads. The number is searched first, so a returning enquirer updates one record and increments a touch count instead of creating duplicates, and the sender gets an immediate acknowledgement.
Escalate a WhatsApp message nobody answered in 15 minutes
Uses Slack and WhatsApp
Logs every inbound WhatsApp message as open, waits fifteen minutes, then re-reads the log. Anything still not marked answered is escalated to Slack with the customer's own words and the time it arrived.
Send the invoice PDF over WhatsApp when a row is marked Paid
Uses Slack and WhatsApp
Watches an invoice ledger for rows marked Paid, pulls the invoice PDF from Google Drive and sends it to the customer as a WhatsApp document, then marks the row as receipted — after the send, never before.
