Zernio WhatsApp API - One API for WhatsApp: messaging, calling, and AI agents
byβ’
You knew Zernio as the API for social media. Now it does WhatsApp too, the whole thing.
Connect a number and you've got the entire WhatsApp Business API behind it: messaging and broadcasts, in-chat forms, calls you can route to AI agents, chatbots, group chats, and numbers in 53 countries. Whatever you need to build on WhatsApp, it's one integration.
Made for developers and the agents they build: REST, SDKs, CLI, and a hosted MCP server.
Official WhatsApp Business API. Zero markup on usage.

Hey PH community!!
Carlos here - the Product Evangelist at Zernio, basically the guy whose job is to make noise about this thing across X, PH, and wherever you hang out.
Joined the crew a month ago and immediately got thrown into the fire. The team was already shipping at warp speed (small team, bootstrapped, zero bullshit), but my mission is crystal clear: get this API in front of every solopreneur, AI agent builder, and tool maker who's tired of wrestling with 15 different platform APIs just to ship social features.
I've been out here posting, threading, and hunting conversations with you guys β the real ones building in public.
Watching this tiny squad (5 people max) ship features that save months of eng time has been wild. No VC theater, just raw execution.
So if you're a builder embedding social into your product, cooking autonomous agents that actually act on X/IG/TikTok, or just tired of the integration tax... hit me up.
Now we are on PH to make Zernio BIG. π
2 days - Thats all it took to be able to ship all of my backend on whatsapp. Real users testing. Zernio cut through all the Meta complexity so I could focus on the actual product especially for customers who never want to touch a website o and most almost never use a website or an app, either old people or just people who hate to learn new UIs, even if they are easy, Zernio allowed me to decrease my Time-to-Value a lot!
Keep it up guys!

@adnanasaliΒ omg, this feedback made by day! thank you π€©
I have a question, how long does it take for approval, because i have a presentation August 12 and this will be useful for me

@daniel_oyetundeΒ happy to help! Could you share a bit more about what you're trying to achieve? If you're looking to integrate the WhatsApp API, it's a 2-minute setup with Zernio. If you're referring to getting a new WA number, some countries like the US provision in seconds, others can take 2-3 days. August 12 is plenty of time either way π

I think Zernio is so cool. We use it ourselves. I think they are just adding more and more massive advantages and just enable you to scale and build content and workflow distribution across multiple channels. Huge respect.

@greenlieberΒ thank you for being with us and the support!
Over 6 month in production with the WhatsApp SDK and it's running very smooth! Never had major issues and I love how much the team improves the product constantly, especially the WhatsApp connection. Heads up to the team for making it easy to connect with my clients and customers through their favorite channel ππ½
Keep building, keep moving
