Can I create HC articles in bulk via the API?

I have hundreds of help center articles that I need to create. Is there a way to do this in bulk via the API?

Here are a few options for creating Help Center Articles.

Zendesk API

The Zendesk API can be used to backup and restore the Help Center Articles. Take a look at the link below.

You can also use the Zendesk Developer Reference to create articles with and API.

I have used this successfully in the past to create and update articles in bulk. I think the best way to generate the data is in an excel spreadsheet to create the PUT command to create each article.

There are 3rd party tools in the Zendesk Store that can also input and synchronize data to the Help center.

If your data resides outside the help center in an existing web site, the Zendesk Federated search tool will allow you to integrate the external data into the help center. Done correctly the search engine will find all the data an end user is looking for with a simple search.
About Zendesk Federated Search – Zendesk help
You can use either of the following methods to implement federated search in your help center:
- Federated Search API - REST API that lets you ingest records of your external content into the Zendesk search indexes. This method requires that your developers build and maintain a middleware layer to integrate the site that hosts the external content with the help center.
- Search crawler - Configurable in the Search settings in Guide, the search crawler lets you implement federated search in your help center without developer resources. You can set up multiple crawlers in your help center search settings to crawl and index different content in the same or different websites.

Let me know if you need any help, I have experience with all of these options.
