❓ Frequently Asked Questions

Will my WhatsApp account get banned?

Sending spam or unsolicited messages in bulk can risk your account. Always send to opted-in contacts only and avoid sending more than 200 messages per hour.

Do my API credentials change after reconnecting?

No. Your API Token and Product ID are generated from your Google login email and are permanent. Even if you delete and recreate a device session, the same credentials will be restored.

Can I send messages to groups?

Yes. Use the group's WhatsApp ID (ends with @g.us) in the to field instead of a phone number.

How many messages can I send per day?

There is no hard limit imposed by Saasilyum. However, WhatsApp may flag accounts that send too many messages too quickly. We recommend a 2–5 second delay between messages for safety.

Can I connect multiple WhatsApp numbers?

Yes. Click "+ Add New Device" in the dashboard multiple times to connect multiple WhatsApp numbers. Each device gets its own Product ID.
