WhatsApp recruitment software built into your ATS
Candidates answer WhatsApp faster than email. OneATS sends interview reminders and updates from your own WhatsApp Business number, records every reply on the candidate's timeline, and handles opt-in, quiet hours and Meta's messaging rules for you.
- Interview reminders
- One-tap RSVP
- Two-way messaging
- Onboarding nudges
Reminders from the real schedule
Invite, 24-hour, 2-hour and 1-hour reminders are sent from the interview itself, never typed by hand.
Replies in one place
Candidate replies appear on their profile next to every email, so the whole team sees the conversation.
Rules handled for you
Only opted-in candidates get messages, nothing goes out between 9 pm and 8 am, and free text is only sent inside WhatsApp's 24-hour window.
Interview reminders
Interview reminders candidates actually read
When you schedule an interview, OneATS can send the invitation on WhatsApp as well as by email, then remind the candidate 24 hours, 2 hours and 1 hour before it starts. The 2-hour reminder is WhatsApp-only. Each reminder is sent once, even if the schedule is saved again.
- Invitation plus 24-hour, 2-hour and 1-hour reminders
- Times in the candidate's message match the interview
- No duplicates: one message per reminder per interview
- Email reminders keep working for candidates who didn't opt in
One-tap RSVP
"Confirm" or "Need to reschedule", in one tap
Candidates answer the reminder with a quick reply. A confirmation marks the interview as accepted. A reschedule request flags the interview and tells the person who scheduled it, so you can offer a new time before the slot is wasted. This matters most for frontline and hourly hiring, where candidates live on their phones.
- Attendance status updates on the interview
- The scheduler is alerted to reschedule requests
- Every reply is recorded on the application timeline
Two-way messaging
Email and WhatsApp in one conversation
The Messages tab on each candidate shows every email and WhatsApp message in order, with delivery and read status. Reply from the same place. Inside WhatsApp's 24-hour customer service window you can write freely; outside it, OneATS offers your approved templates, so a message is never blocked by WhatsApp's rules.
- Email and WhatsApp history in one thread
- Sent, delivered, read and failed status on each message
- Free text inside the 24-hour window, templates outside it
- Replies visible to the whole hiring team
Onboarding nudges
Nudges that get offers answered and documents in
Once a candidate is in onboarding, OneATS reminds them on WhatsApp when their offer expires in 48 hours. It also reminds them on day 2 and day 5 if joining documents are still missing.
- Offer expiring in 48 hours
- Pending documents on day 2 and day 5
- Same opt-in and quiet-hour rules as every other message
Direct connection
Your WhatsApp Business number, connected in an afternoon
Connect the WhatsApp Business account you already own through Meta's WhatsApp Cloud API, or through Gupshup. Settings walks you through each step: the IDs to copy, the token to create and your own callback URL. Credentials are encrypted, and each company's incoming messages are checked against its own Meta app secret.
- Meta WhatsApp Cloud API or Gupshup
- Step-by-step setup guide inside Settings
- Daily sending limit you control
- Credentials encrypted and never shown again
Compliance
Consent first, and no messages at night
Candidates choose to receive WhatsApp messages when they apply, and OneATS stores that choice. Messages to anyone who hasn't opted in are refused and logged. Anything triggered between 9 pm and 8 am in your company's time zone waits until morning. Interview reminders that would arrive after the interview are dropped.
- Opt-in captured on the application form
- Quiet hours 21:00–08:00 in your company's time zone
- Late reminders dropped, not sent after the interview
- Every message logged with its status

FAQ
Frequently asked questions
Do I need the WhatsApp Business API?
Yes, for reminders and two-way messages. You connect your own number through Meta's WhatsApp Cloud API or Gupshup. To simply share a job link on WhatsApp, you don't need it.
Who pays for WhatsApp messages?
Meta (or Gupshup) bills your business directly for conversations, under your account with them. OneATS doesn't add a per-message charge.
Will candidates get messages they didn't ask for?
No. Only candidates who opted in when they applied get automated WhatsApp messages, and nothing goes out between 9 pm and 8 am.
What is the 24-hour window?
WhatsApp lets a business send free text only within 24 hours of the candidate's last message. Outside that window you must use an approved template. OneATS shows which applies and offers your templates when needed.
Does it work with my existing WhatsApp number?
It needs a number registered on the WhatsApp Business Platform. A number in use on the normal WhatsApp app has to be moved to the platform first (Meta's rule).
Can I see whether reminders reduce no-shows?
Interview analytics shows the no-show rate of candidates who opted in to WhatsApp next to those who didn't. That's a comparison, not proof of cause, but it's a useful signal.
