Marketing, utility, authentication, service: what each one is

Every WhatsApp Business API message falls into one of four categories. The category, not the length or the media, decides the price.

Needs an approved marketing template

Utility message · ₹0.25

Updates about a transaction or service the customer already has: order confirmed or shipped, payment received, appointment tomorrow, fee or EMI due. No promotional lines.

Needs an approved utility template

Authentication message · ₹0.25

Only one-time passwords and verification codes, with a copy-code button and an optional expiry line. No promotions and no links.

Needs an approved authentication template

Service message · ₹0.13

A free-form reply you send within 24 hours of the customer's last message, usually from the live chat inbox. Text, images, documents, audio, video, location, stickers or reactions.

Setup & monthly fee

No setup fee, no monthly charge: the full WhatsApp bill

On Fast2SMS the WhatsApp Business API itself costs nothing. There is no setup fee, no monthly panel rental, no per-number fee and no per-agent fee. Onboarding, the live chat inbox, the chatbot, the API and webhooks come with every account.

Your monthly cost is simply the messages you sent that month, each at the rate of its category. A slow month costs nothing, because the wallet balance never expires.

Meta categories

How Meta decides the category, and the price

Every message you send first, such as a campaign, an alert or an OTP, uses a template. You pick a category when you create it, and Meta checks two things: that the content follows WhatsApp's policies and that the category matches the content. Approval usually takes from a few minutes to a few hours.

Keep promotions out of utility templates: a discount line inside a utility template is a common reason for rejection or re-categorisation. Replies inside the 24-hour window after a customer writes to you need no template and are service messages. The Fast2SMS team reviews your templates for free before you submit them.

Example month

A month of WhatsApp for an online store

Total for the month: ₹11,150. No setup or monthly fee is added.

Can I put an offer inside a utility template to pay less?
