Grabbed a loaf on the way to work and it was still warm. Worth the queue.

Response from the ownerThanks Elias. Fresh batches come out at seven, and the listing says so on its own.

Why Zernio vs Google Business Profile API?

Save 4-6 weeks of development time

Zernio API

Simple API key - start in 30 seconds
Automatic retries & queue management
Upload directly - we handle Google's format
Zero maintenance forever
One API for 17 platforms

Google Business Profile API

Complex OAuth with Google Cloud Console setup
Quota limits and API request management
Location verification and media requirements
Multiple Google APIs to integrate
Build separate integrations per platform

How It Works

Three steps to Google Business automation

1

Profile

default

Google Business

Connect your business

Link your Google Business Profile through our dashboard. One-click OAuth - we handle all the Google permissions and locations.

2

POST /v1/posts

const { data } = await zernio.posts.createPost({
  body: {
    content: 'Now open on Saturdays',
    mediaItems: [{ url: 'https://cdn.acme.com/launch.jpg' }],
    platforms: [
      { platform: 'googlebusiness', accountId: 'acc_8f2a' },
    ],
    scheduledFor: '2027-01-15T14:30:00',
    timezone: 'Europe/Madrid',
  },
});

Build your integration

Use our simple REST API to schedule updates, events, and offers for any of your locations. Same pattern works for all 17 platforms.

We handle the rest

Zernio publishes at your scheduled time, retries on failures, and notifies you via webhooks. You never touch Google's API directly.

You need a verified Google Business Profile to post updates

Features

Everything you need to ship Google Business features

Reviews

Read a location's reviews and post or update the owner's reply.

Events

Publish an event post with its own title and date range.

Posts

Publish updates, events, and offers that appear in Google Search and Maps.

Multi-location

Add every location from one Google account without connecting each separately.

Business profile

Read and update hours, description, phone, photos, and links.

Menu

Publish and update the location's food menus and service list.

Integrate

Three ways in. Same API behind all of them

Write it yourself with the SDKs, hand it to an agent over MCP, or run it from a shell.

import Zernio from '@zernio/node';

const zernio = new Zernio(); // reads ZERNIO_API_KEY

const { data: post } = await zernio.posts.createPost({

body: {

content: 'Now open on Saturdays',

mediaItems: [{ type: 'image', url: 'https://cdn.acme.com/launch.jpg' }],

platforms: [

{

platform: 'googlebusiness',

accountId: 'acc_xxx',

platformSpecificData: {

callToAction: { type: 'LEARN_MORE', url: 'https://acme.com' },

},

},

],

publishNow: true,

},

});
