Plugins play a vital role in customizing and enhancing your WordPress sites. They are used to add functionality like contact forms, ecommerce, and analytics to your sites with no coding required.
Like WordPress, which receives regular updates, plugins also receive regular updates to add new features, patch a security hole, increase compatibility, and more. That’s why Kinsta included Plugin and Theme Management among the tools available within MyKinsta for each of your sites.
However, updating plugins across many sites can still be daunting for busy customers like agencies. This article demonstrates a solution that uses the Kinsta API to simultaneously manage plugins across multiple sites.
