Frequently Asked Questions

▶Why not just use WhatsApp Business API?

WhatsApp Business API is great for automated messaging at scale, but it requires technical setup and ongoing costs. NumSwift is for agents who need to quickly message a customer from a ticket right now, with zero setup. The two approaches complement each other.

▶Can multiple support agents use this?

Yes. Since NumSwift runs entirely in the browser with no account required, any team member can open it and start messaging customers. There is nothing to install, no credentials to share, and no per-seat licensing.

▶Does it work if the customer is in another country?

Absolutely. Paste the number as it appears in your ticket, select the customer's country, and NumSwift will format it with the correct international prefix. This is especially useful for support teams handling customers across multiple regions.

▶Will the customer see my personal phone number?

When you open a WhatsApp chat through NumSwift, it uses your WhatsApp account on that device. The customer will see whatever number is associated with your WhatsApp. If privacy is a concern, use a dedicated support phone with WhatsApp Business installed.
