Businesses want to maintain their brand presence on Zalo OA, but manually drafting and publishing posts takes far too much time. Manually aligning images? Too frustrating. That's why the automatic Zalo OA posting system was created through the n8n tool combined with artificial intelligence (AI). This solution helps businesses automate 90% of the content creation and publishing process.

A complete automatic Zalo OA posting system built on n8n.

Why are n8n and AI the perfect pair for Zalo OA?

n8n serves as the backbone for orchestrating workflow automation. AI from DPS.MEDIA acts as the brain, producing SEO-optimized content from requested keywords or original articles.

After implementing this automated n8n flow, the Nhã Kỳ Cosmetics chain saved 15 working hours per week for its administration team. At the same time, their posting frequency increased to 3 posts per week consistently without any additional staffing costs.

You can learn more about the power of automation in the n8n documentation to better understand how connected nodes work.

Set up an automatic Zalo OA posting workflow with n8n

The automated workflow is designed through two independent yet closely integrated scenarios on the n8n platform.

Flow 1: Authenticate the Zalo OA account and automatically refresh the token

Zalo OA requires a high level of security, with the Access Token valid for only 25 hours and the Refresh Token for 30 days. Without automatic refreshing, your workflow will be interrupted continuously.

The account authentication flow completely solves this issue by setting up a separate scenario to manage the login session.

A Webhook receives the initial authorization code from the developer account. Then the HTTP Request node sends a request to obtain the latest Access Token and Refresh Token pair based on the Zalo OA API documentation.

Finally, the system stores the token pair in the database and automatically triggers the refresh process every 24 hours through the Schedule Trigger.

Flow 2: AI-powered content creation and automatic publishing

When a new post is requested, the post processing flow is triggered automatically. The system receives input data including the post title and accompanying primary keywords.

The Message a model node calls DPS.MEDIA AI to automatically transform the raw article into a highly engaging Zalo OA post format. The final HTTP Request node executes a POST request to send all content and images to the Zalo system.

Real-world results in the Zalo OA administration interface

Once connected successfully, all AI-generated articles appear directly in the business's content management page.
