How to see if a Webflow Collection already contains an item?

Hi, I have a Webflow Collection with a username field and some other fields. How do I do the following:

  1. First, check if a username already exists in the Collection. If it already exists, update some fields for the username.
  2. If not, then create a new entry in the Collection.

In other words, how can I check what are all the items in a Collection? do i need to use Zapier Webhook for this?


thank you.

App APIs can be used in Zaps with the Webhooks app as an action step:

NOTE: You’ll likely also need to use a Code step to handle/filter the array of line items returned:



thank you!
