I need WhatsApp wired into our recruitment flow so job seekers automatically receive application status updates the moment we change a stage in our ATS. The purpose is strictly job notifications—no marketing, no interview reminders—just clear progress messages that keep candidates engaged. My end of the stack can fire a webhook or expose a REST endpoint whenever a record changes to “received”, “under review”, “short-listed”, “rejected” or “offer made”. From there, the solution you build should pick the correct pre-approved WhatsApp Business template, populate the dynamic fields (name, role, status) and push it out reliably. Twilio, Meta Cloud API or an equivalent compliant gateway is fine as long as delivery reporting is included. Deliverables • Live WhatsApp Business integration connected to the webhook • Four reusable message templates covering the statuses above • Basic log showing sent, delivered and failed states, exportable as CSV • Docker-ready deployment or clear setup script with README so my team can reproduce it on staging and production Acceptance criteria: a test candidate on our staging ATS receives the correct status message within 30 seconds of the webhook event, and the log displays the WhatsApp message ID with a delivered flag. That’s the entire scope—once it sends, logs and can be redeployed, the project is done.
