Best practices for WhatsApp OTP implementation
Obtain consent
Always collect explicit user consent before sending WhatsApp authentication messages. This ensures users expect and trust the messages they receive.
Check WhatsApp installation
Using our verification APIs, you can automatically check if WhatsApp is installed on a user’s device and suggest it as the preferred OTP channel (available only on Android).
Give users a choice
Let users choose their preferred authentication channel (WhatsApp, SMS, email, etc.) for flexibility and better experience.
Enable zero-taps
Remove friction by enabling zero-tap verification where possible, so users don’t need to leave WhatsApp.
Ensure the highest deliverability rates for verification messages at every touchpoint
Wondering whether to use WhatsApp, SMS or email for sending OTPs? No need – automate sending OTPs on the best channel and only pay for what gets delivered.
Cost and ROI of WhatsApp OTPs
WhatsApp OTPs are sent as Authentication templated messages and are billed on a per‑message basis.
Each delivered template is charged at Infobip’s WhatsApp price, which includes the Meta fee (parent company of WhatsApp). If you deliver multiple OTP templates in a flow or via retries, each one is billed separately.
