Why being an official Meta Tech Provider matters for your WhatsApp
Your customers connect their own number through Meta's official flow, keep everything in their name and pay Meta with no markup.

Meta approved Grostify as a Tech Provider. In practice it means we can onboard and operate other companies' WhatsApp Business accounts through Meta's own tools, with nothing in between.
The number stays in your customer's name
Your customer links their number in Meta's Embedded Signup popup. There are no copied tokens and no System Users to share. The business portfolio, the WhatsApp account and the number are theirs, and nothing is tied to a middleman.
Signed events, no surprises
Every webhook event arrives verified with HMAC-SHA256 and deduplicated, so a retry from Meta is not processed twice.
Meta's cost, with no markup
Your customer pays Meta directly for conversations. We charge for the platform, not for the messages.
Official access is what lets a customer leave whenever they want and take their number with them.
Your API, answering on WhatsApp
Once the number is connected, the WhatsApp assistant answers each linked user with real data from your API, using the same tools you publish for Claude and ChatGPT.
