Create updates, offers, CTAs, and other Google Business post types

Quick Start

Create a Google Business Profile post with an image:

const { post } = await zernio.posts.createPost({
  content: 'We are open this holiday weekend! Stop by for our special seasonal menu.',
  mediaItems: [
    { type: 'image', url: 'https://example.com/holiday-special.jpg' }
  ],
  platforms: [
    { platform: 'googlebusiness', accountId: 'YOUR_ACCOUNT_ID' }
  ],
  publishNow: true
});
console.log('Posted to Google Business!', post._id);

result = client.posts.create_post(
    content="We are open this holiday weekend! Stop by for our special seasonal menu.",
    media_items=[
        {"type": "image", "url": "https://example.com/holiday-special.jpg"}
    ],
    platforms=[
        {"platform": "googlebusiness", "accountId": "YOUR_ACCOUNT_ID"}
    ],
    publish_now=True
)
post = result.post
print(f"Posted to Google Business! {post['_id']}")

curl -X POST https://zernio.com/api/v1/posts \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "content": "We are open this holiday weekend! Stop by for our special seasonal menu.",
    "mediaItems": [
      {"type": "image", "url": "https://example.com/holiday-special.jpg"}
    ],
    "platforms": [
      {"platform": "googlebusiness", "accountId": "YOUR_ACCOUNT_ID"}
    ],
    "publishNow": true
  }'

Content Types

Text + Image Post

The most common and recommended post type. A single image with text. No contentType field is needed -- this is the default when media is included.

const { post } = await zernio.posts.createPost({
  content: 'Fresh seasonal menu available now! Visit us to try our new dishes.',
  mediaItems: [
    { type: 'image', url: 'https://example.com/seasonal-menu.jpg' }
  ],
  platforms: [
    { platform: 'googlebusiness', accountId: 'YOUR_ACCOUNT_ID' }
  ],
  publishNow: true
});

result = client.posts.create_post(
    content="Fresh seasonal menu available now! Visit us to try our new dishes.",
    media_items=[
        {"type": "image", "url": "https://example.com/seasonal-menu.jpg"}
    ],
    platforms=[
        {"platform": "googlebusiness", "accountId": "YOUR_ACCOUNT_ID"}
    ],
    publish_now=True
)

curl -X POST https://zernio.com/api/v1/posts \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "content": "Fresh seasonal menu available now! Visit us to try our new dishes.",
    "mediaItems": [
      {"type": "image", "url": "https://example.com/seasonal-menu.jpg"}
    ],
    "platforms": [
      {"platform": "googlebusiness", "accountId": "YOUR_ACCOUNT_ID"}
    ],
    "publishNow": true
  }'

Text-Only Post

Text-only posts are supported but have lower visibility on Google Search and Maps. Adding an image or CTA is recommended.

const { post } = await zernio.posts.createPost({
  content: 'Happy Friday! We are offering 20% off all services this weekend. Mention this post when you visit!',
  platforms: [
    { platform: 'googlebusiness', accountId: 'YOUR_ACCOUNT_ID' }
  ],
  publishNow: true
});

result = client.posts.create_post(
    content="Happy Friday! We are offering 20% off all services this weekend. Mention this post when you visit!",
    platforms=[
        {"platform": "googlebusiness", "accountId": "YOUR_ACCOUNT_ID"}
    ],
    publish_now=True
)

curl -X POST https://zernio.com/api/v1/posts \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "content": "Happy Friday! We are offering 20% off all services this weekend. Mention this post when you visit!",
    "platforms": [
      {"platform": "googlebusiness", "accountId": "YOUR_ACCOUNT_ID"}
    ],
    "publishNow": true
  }'

Post with CTA Button

Add a call-to-action button to drive traffic. The CTA appears as a prominent button below the post content.

const { post } = await zernio.posts.createPost({
  content: 'Book your appointment today! Limited spots available this week.',
  mediaItems: [
    { type: 'image', url: 'https://example.com/booking.jpg' }
  ],
  platforms: [{
    platform: 'googlebusiness',
    accountId: 'YOUR_ACCOUNT_ID',
    platformSpecificData: {
      callToAction: {
        type: 'BOOK',
        url: 'https://mybusiness.com/book'
      }
    }
  }],
  publishNow: true
});

result = client.posts.create_post(
    content="Book your appointment today! Limited spots available this week.",
    media_items=[
        {"type": "image", "url": "https://example.com/booking.jpg"}

                "url": "https://mybusiness.com/book"
            }
        }
    }],
    publish_now=True
)

curl -X POST https://zernio.com/api/v1/posts \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "content": "Book your appointment today! Limited spots available this week.",
