Insert or update item in a CMS collection Webflow

[samliew]

Welcome to the Make community!

You’ll need to fetch the existing list of items before you can create a filter against the array of items.

To make an array, use an array aggregator module.

Then, use a router with filters to check the field against the array of existing Webflow items.

Aggregators

Every result (item/record) from iterator/list/search/match modules will output a bundle. This can result in multiple bundles, which then trigger multiple operations in future modules (one operation per bundle). To “combine” multiple bundles into a single variable, you’ll need to use an aggregator of some sort.

Aggregators are modules that accumulate multiple bundles into one single bundle. An example of a commonly-used aggregator module is the Array aggregator module. The next popular aggregator is the Text Aggregator which is very flexible and can apply to many use-cases like building of JSON, CSV, HTML.

There are other types of aggregator modules, click the below links to find out more:
