Automate Kinsta workflows with Zapier & Kinsta API

Managing a large stable of WordPress sites usually requires a lot of clicking to execute repetitive tasks in administrative dashboards.

And as a WordPress administrator for an agency, you know automating repetitive tasks can save time. That’s the power of the Kinsta API. You can perform the same operational tasks normally run within MyKinsta without logging in.

Automation sounds like code: writing scripts, managing infrastructure, and having the programming expertise to glue everything together. But today, with automation tools like Zapier, n8n, and others, that barrier is much lower. You can schedule actions, loop through results, add conditions, handle asynchronous operations, and even send reports to Slack without writing a single line of code.

This article shows how Zapier can act as a workflow layer on top of the Kinsta API. Once you understand the pattern, you can apply it to almost anything.

How Zapier works with the Kinsta API

At a simple level, Zapier connects a trigger to one or more actions. A trigger can be something scheduled, like every Sunday at 2 a.m. It can also be something that happens, like a Slack message, a form submission, or even a manual button click in Zapier.

An action is what runs after the trigger. In our case, that action is usually a call to the Kinsta API.

Zapier has a built-in Webhooks tool that can generate HTTP requests. That means you can send GET, POST, PUT, or DELETE requests directly to the Kinsta API endpoints.

For example, the action above makes a GET request to the /sites endpoint to get a list of all WordPress sites in my company account.

You can also securely pass your API key and include the required parameters, such as environment_id, and Zapier handles the request.

Where it becomes powerful is when you start combining steps. You can fetch all your sites first. Then loop through each site.

As shown in the image above, we extract the site_id and site_name for each site, then pass the site_id to fetch environments in another action.

In the example below, after retrieving the site ID, we use other actions to loop through, check for available plugin updates, and, if updates are available, run them. If not, skip.

This is just one example of what can be done with Zapier. You can build a massive workflow without writing any line of code.

Another benefit is that you also have access to the Zapier AI agent or copilot, a chat interface similar to Claude that lets you explain what you need, share the API endpoints and parameters, and have it handle everything for you.

This gives you a big advantage as an agency.

Workflows you can build with Zapier and the Kinsta API

Once you understand that Zapier can trigger API calls, loop through results, and handle conditions, you start seeing real operational use cases.

Here are four that make sense in day-to-day agency work.

1. Scheduled maintenance across multiple sites

Plugin updates are not complicated, and in fact, with MyKinsta, you can do this within your MyKinsta dashboard, even across multiple sites, via Bulk Actions.

But if you don’t want to log into MyKinsta, or if you want to schedule this action or attach it to a specific workflow, Zapier can help.

With Zapier and the Kinsta API, you can create a scheduled workflow. For example, Zapier runs automatically every Sunday at 2 a.m. and fetches all your WordPress sites, retrieves their environments, checks which plugins have updates available, and updates only those that do. After each update, it confirms that the operation completed successfully. Once done, it clears the cache to ensure changes are reflected immediately.

This way, you move from manual checking to structured oversight. And when you multiply that across dozens of sites, the time saved becomes significant.
