WhatsApp Business API guides — frequently asked
Questions buyers ask before going down the guides rabbit hole.
Where should I start if I'm completely new to the WhatsApp Business API?
Start with three guides in this order. (1) "WhatsApp Business app vs API" — explains why the API matters for a real team. (2) "WhatsApp Business API pricing" — what Meta charges so you can budget. (3) "How to get the WhatsApp Business API" — actual filing steps. After those three, the rest of the catalog is à la carte based on your specific use case.
I'm already on WATI / AiSensy / another platform. Which guide do I read?
Category 7 above has a dedicated "Switch from [your platform]" guide for 13 of the most common WhatsApp BSPs. Each covers number migration, template re-approval, contact carry-over, and the gotchas specific to that platform's data export.
Are these guides written for technical or non-technical buyers?
Non-technical. Every guide leads with the plain-English buyer question (what does it cost, will my number get banned, can I integrate with Shopify) and only goes into the technical detail when it matters for decision-making.
How often are these guides updated?
Quarterly minimum, more often when Meta changes WhatsApp Business API policy (pricing tiers, template categories, conversation windows). Each guide has a "last updated" date at the top. When Meta ships a major policy change, the affected guides are revised within two weeks.
Can I ask a question that isn't covered by any of these 65 guides?
Yes — email [email protected] or book a walkthrough. Most buyer questions get added to the relevant guide if they're general; some get answered directly and stay private if they're specific to your business.
Is there a difference between a "guide" and a "case study" on this site?
Yes. Guides are educational and platform-agnostic — they teach concepts. Case studies (under /case-studies/) document specific Go4whatsup customers and their results. Guides are the "what and how"; case studies are the "who already did it and what happened."
