plentyShop plugins

Welcome to the developers documentation for the plentyShop plugins Ceres and IO.

On here, you will find ressources that help you customise your online shop template. If you find anything we can improve, make sure to leave a feedback comment at the bottom of the respective page or by clicking the speech bubble in the upper right corner.

Ceres & IO

Our Template guide is your entry point for developing for plentyShop.

If you’re looking for changes between older Ceres versions and Ceres 5.0, the Update guide will prove useful.

We’ve also expanded the reference documentation on properties and methods used in Ceres' and IO’s PHP classes.


If you want to customise widgets or work on your own, you should begin with the ShopBuilder tutorial^.

Developer Talk

Every monday at 3 p.m. (CEST), we’re offering office hours with one or two of our plentyShop developers. If you can make time, come join us in this Google Meets call. Our developers will do their best to help you out with any issues or questions you might have regarding the development for plentyShop. If you want to give the team more time to prepare, you can post any concrete questions in the corresponding forum thread.

Visit our forum

If there are issues that cannot be solved in the Developer Talk, you can always open a new thread in our forum. Dependinn on its compelxity, tt might take a few days before our developers can have a look at your issue. Either open a new topic in our Ceres category or in the category for plugin development.
