WhatsApp API pricing questions

How is the WhatsApp API cost calculated?

For each category, the calculator multiplies billable delivered messages by the matching recipient-market rate. Published volume tiers are applied marginally where available. The category costs are added together to show estimated monthly Meta charges.

Which currency should I choose?

Choose your Meta account’s billing currency. INR and USD load their own published rate cards. Switching currency does not simply change the symbol or convert the same numeric rate. Check your account settings before budgeting.

What should I enter for Service and free-window messages?

Enter only the billable quantity after the allowances or exemptions applicable to your account. Meta’s public overview and calculator currently show inconsistent Service treatment, so the preset follows its calculator data. Confirm current billing rules in WhatsApp Manager or the linked Meta documentation. Rate options let you enter your actual effective rate.

Does this include Sendwo software or tax?

No. This estimate covers Meta messaging charges, with 0% Sendwo API markup. Add your selected Sendwo software subscription and any applicable taxes separately. This keeps the message estimate easy to understand.

When should I change the rate options?

Select Authentication International only if Meta’s rules apply to your traffic. Use custom rates when your current rate card, negotiated effective rate or billing terms differ from the dated snapshot. Custom flat rates replace the automatic volume-tier calculation.

Can I use this for several countries?

Calculate each recipient market separately and add the results in the same billing currency. Treat the entered quantities as your total monthly billable traffic for that market, so published tier estimates are meaningful.

Presets use the INR and USD data supplied by Meta’s public pricing calculator, checked 5 Nov 2026. Your current rate card, category eligibility, billing currency and account terms govern the final charge.
