“We're now at the level where we're thinking, this is actually pretty good to have in our platform. But as soon as clients ask for more, I know with Zernio we can add those things quickly.”

The challenge
ACT.agency is an advertising, content and technology agency in Amsterdam, working with brands like Odido, LG and Nationale-Nederlanden. With around 35 people, their tech team had already built ACT's own AI suite, and social was meant to be one more module inside it.
Then they costed out the module.
“The biggest headache for us is integrating six main channels that every big brand uses. Instagram, TikTok, LinkedIn, YouTube, Facebook. All those API endpoints constantly change. Keeping track of that is a real big hassle.”
They researched building direct integrations to each platform, and faced different endpoints, code shapes, and release cycles. For a team whose actual product is brand work, that's a permanent maintenance bill on something clients never see.
The second problem was presenting the value of their own work. ACT runs both sides of a client's social presence: the brand content and the advertising behind it. But when a post takes off, the client doesn't see two numbers. They see one.
“You get your post at 10 million views. But of those 10 million, 9.9 million are paid. The platform doesn't separate that data.”
Every platform bundles organic and paid reach into a single stream. That makes it hard to show a client which part of the results came from the content itself and which came from the media spend behind it. Exactly the split ACT needs to prove the value of both sides of what they do.
Why Zernio
Three things made Zernio the pick.
It is API-first, with every channel behind one API.
It is AI agent friendly, which makes building on top of the documentation fast.
And it is white-label from the start, which mattered most: whatever ACT built had to sit behind their own brand, in their own suite, with no third-party tool visible to the client.
“At the front end, we don't want you to see Zernio. The white-label stuff you added for connecting accounts makes a lot of sense for us.”
What they built
ACT started with the Analytics API and expanded from there. Every client gets a white-labeled workspace with their own connected channels. Inside it, post-level insights, follower growth over time, and platform-level dashboards ACT designed themselves. Posts are measured every minute.
Social media publishing came next. ACT built a full content calendar and posting flow on top of Zernio's Posting API, so planning, scheduling and publishing all happen inside their platform.
Then the inbox. Every Instagram and Facebook conversation across every client account runs through the same API into ACT's platform, around 86,000 messages a month. The team answers them from one conversation layer instead of logging into a separate inbox for each brand.
Last came the Ads API, connected across Meta ad accounts and used purely for monitoring. ACT doesn't buy media through it, but they use the API endpoints to pull performance. That's what closes the reporting gap: organic performance from the Analytics API, paid performance from the Ads API, both through one integration, split apart for the client instead of bundled together.
Facebook and Instagram are covered today. TikTok, where the same bundling problem exists, is the one ACT wants next.
When the Node.js SDK shipped on Zernio, ACT moved the integration onto it.
“Based on the Node.js SDK, everything becomes even easier because all the new functionality and changes are already included in the SDK updates. And today, with AI agents, it's really easy to update those things with Zernio Docs.”
The results
- ·Organic and paid, split apart. Every client report now separates what the content earned from what the ad spend added. On Facebook and Instagram, post by post, in ACT's own dashboards. Neither platform breaks that out on its own, so ACT can show the value of the brand work and the media work as two numbers instead of defending one.
- ·Onboarding a new client is a workspace, not a project. Eight client workspaces run on the same integration, each with its own connected channels.
- ·One inbox instead of one per brand. Around 86,000 Instagram and Facebook messages a month reach the team through a single conversation layer inside ACT's own platform.
- ·No more spreadsheet exports from Ads Manager. 1,336 ads are tracked programmatically, alongside the organic numbers.
- ·Nobody at ACT maintains platform integrations. Six social channels and Meta ad accounts sit behind one API, and platform changes land in the SDK rather than in ACT's backlog.
- ·No client has ever seen the word Zernio. Account connection, publishing, inbox and reporting all carry ACT's brand.
