WhatsApp Automation
24-hour window awareness, baked in.
Every part of Callswala — inbox, workflows, broadcast — knows whether a conversation is inside or outside the 24-hour service window, and whether you can send free-form or must use a template.
The problem
Most WhatsApp tools quietly violate the 24-hour rule, leading to template rejections or account restrictions.
How Callswala solves it
Callswala surfaces the window state on every thread, blocks invalid sends, and lets workflows branch on the window-check node.
What you get
Per-thread window state
See exactly when the window opened and when it expires.
Category labels on every conversation

Does this affect my Meta billing directly?▾
Yes — fewer mistakes = fewer rejected templates = lower Meta charges.
