- [WhatsApp Pricing: Message categories](https://kapso.com/guides/whatsapp-pricing/how-pricing-works/message-categories): Meta prices per category: marketing, utility, authentication and service. Meta decides which one a template gets, and can change it after approval.
- [WhatsApp Pricing: The 24-hour window](https://kapso.com/guides/whatsapp-pricing/how-pricing-works/the-24-hour-window): A customer message opens a 24-hour window. Through September 30 it makes service replies and utility templates free; October changes that.
- [WhatsApp Pricing: Pricing by country](https://kapso.com/guides/whatsapp-pricing/how-pricing-works/pricing-by-country): The rate depends on your recipient's country, not yours. When there's no phone number, the country comes from the BSUID prefix instead.
- [WhatsApp Pricing: How a message gets priced](https://kapso.com/guides/whatsapp-pricing/how-pricing-works/how-a-message-gets-priced): You can estimate the price of a message at send time. The price that actually bills arrives after delivery, on the status webhook.
- [WhatsApp Pricing: Pricing inside the service window](https://kapso.com/guides/whatsapp-pricing/october-1-2026/service-message-pricing): From October 1, 2026, service messages and utility templates inside the customer service window are billed at each market's utility rate.
- [WhatsApp Pricing: Estimating your exposure](https://kapso.com/guides/whatsapp-pricing/october-1-2026/estimating-your-exposure): A repeatable method for working out what October 1 does to your own bill, using message history you already have.

- [WhatsApp Pricing: Before October 1](https://kapso.com/guides/whatsapp-pricing/october-1-2026/before-october-1): The guide in four sentences, and a four-step checklist to work through before October 1.
- [Business-scoped user IDs: Usernames and BSUIDs](https://kapso.com/guides/business-scoped-user-ids/introduction/usernames-and-bsuids): Meta added BSUIDs to every webhook in April 2026 and is only now removing phone numbers. Usernames and BSUIDs are separate features, and you get a BSUID whether or not the user has a username.
- [Business-scoped user IDs: Reading the new payload](https://kapso.com/guides/business-scoped-user-ids/introduction/reading-the-new-payload): An inbound message can carry a phone number, a BSUID and a username. Which of them actually arrive depends on the user and on how far the rollout has reached them.
- [Business-scoped user IDs: Portfolio scoping](https://kapso.com/guides/business-scoped-user-ids/identity/portfolio-scoping): A BSUID is scoped to a business portfolio, not to a WABA and not to a phone number. The same person can have more than one, and they don't work across portfolios.
- [Business-scoped user IDs: Matching and merging](https://kapso.com/guides/business-scoped-user-ids/identity/matching-and-merging): When the phone number stops arriving, a lookup by phone misses and creates a second record for a customer you already have. There's no way to merge the two afterwards.
- [Business-scoped user IDs: Sending to a BSUID](https://kapso.com/guides/business-scoped-user-ids/messaging/sending-to-a-bsuid): A send can address a phone number, a BSUID, or both. If you send both, Meta uses the phone number, and authentication templates won't accept a BSUID at all.
- [Business-scoped user IDs: Asking for a phone number](https://kapso.com/guides/business-scoped-user-ids/messaging/asking-for-a-phone-number): A button asks the user to share their number, and Meta's contact book stores the ones you've already exchanged messages with. Expect a growing share to decline.
- [Business-scoped user IDs: Migration checklist](https://kapso.com/guides/business-scoped-user-ids/messaging/migration-checklist): Every change the guide covered, grouped by storage, inbound, outbound and downstream, plus what Kapso already handles.
