Using property expansion and limiting to shape the Delivery API output
This article explains the mechanics of property expansion and limiting in depth. If you haven't already, please read the Getting started article first - in particular the "Concepts" section.
Property expansion and limiting applies only to select property editors. The following built-in property editors in Umbraco support expansion and limiting:
Picker editors
Content Picker
Media Picker
Media Picker (legacy)
Multinode Treepicker
Block-based editors
Block List
Block Grid
Rich Text Editor (with blocks)
When working with property expansion and limiting in API queries, there are two rules of thumb to keep in mind:
Expandable properties are not expanded by default. They must be expanded explicitly.
All properties are included in the API output by default. We can apply limiting to limit the included properties.
In the following examples, we will be querying a content tree with blog posts and blog authors:
All blog posts are located under a root content item called "Posts".
All authors are located under a root content item called "Authors".
The blog post content type (post) contains two properties that support expansion and limiting:
author: A content picker for picking the author of the post.
coverImage: A media picker for picking an image for the post.
The author content type (author) contains a single property that supports expansion and limiting:
picture: A media picker for picking a picture of the author.
When fetching a blog post, the author and coverImage properties are returned in their un-expanded representation by default. This representation does not contain any property data; the properties collections of author and coverImage are empty:

}If we want to show the author's picture when rendering the blog post, we need to expand the author property. By expanding the property, the author properties (including picture) are included in the output. We can achieve this by appending the expand parameter to our request.
The expand parameter syntax is as follows:
expand=properties[propertyAlias1,propertyAlias2,propertyAlias3]
Within the properties part of the expand parameter we can list the aliases of the properties we wish to expand. If we want to expand all expandable properties, we can use the operator $all instead:
expand=properties[$all]

}Now we have the picture data in the properties collection of author. However, the rest of the author's properties (biography and dateOfBirth) are also present in our output, so we are slightly over-fetching. We will take care of that later.
First, we need to get the alt texts of our images (the blog post coverImage and the author picture). The alt text in this case is a text string property (altText) on the media type. Fetching the alt texts is possible because property expansion can be performed both across multiple properties and in a nested fashion.
For nested property expansion, the expand parameter syntax is as follows:
expand=properties[propertyAlias[properties[nestedPropertyAlias1,nestedPropertyAlias2]]]
Nested property expansion can also be combined with the $all operator:
expand=properties[$all[properties[nestedPropertyAlias1,nestedPropertyAlias2]]]
There is no API limit to how "deep" the nesting can go. Eventually though, the total length of the request URL may become a hard limit to the size of the query.
Let's amend the expand parameter to accommodate expansion of the images:
Request
GET /umbraco/delivery/api/v2/content/item/set-your-content-free/
?expand=properties[coverImage,author[properties[picture]]]

}As mentioned above we are slightly over-fetching. We don't need all the author data - we are only interested in the author's picture. To fix this we can apply property limiting by adding the fields parameter to our request.
The fields parameter allows us to limit the properties in the output to only those specified. The parameter uses the same syntax as the expand parameter.
Our ideal blog post output contains:
All the properties of the blog post, including the altText of the post coverImage.
Only the picture property of author, including the altText of the author picture.
As with property expansion, we can use the $all operator in the fields parameter. This will include everything at any given query level. We'll use this to include all the blog post properties in the output without having to specify each property explicitly:
Request
GET /umbraco/delivery/api/v2/content/item/set-your-content-free/
?expand=properties[coverImage,author[properties[picture]]]
&fields=properties[$all[properties[altText,picture[properties[altText]]]]]

}Now the API output contains only the properties we need to render the blog post.
Property limiting is particularly useful when querying multiple items. For example, if we were building a condensed list of blog posts, we likely wouldn't need the author data nor the blog post content. By applying limiting to a filtered query, we can tailor the API output specifically to this scenario:
Request
GET /umbraco/delivery/api/v2/content/
?filter=contentType:post
&expand=properties[coverImage]
&fields=properties[excerpt,tags,coverImage[properties[altText]]]

}If you are not familiar with block-based editors, please refer to this article for the general concepts of these.
In the API output, a block has little value without its contained properties. Therefore, the content and settings properties of blocks are always included in the output. However, these properties are not expanded. As such, we can apply expansion and limiting to the contained properties.
In the following examples we'll request different types of articles, all of which are located under a root content item called "Articles":
An article with a Block List property (blockList).
An article with a Block Grid property (blockGrid).
An article with a Rich Text Editor property (richText).
All these properties are configured with a "Featured Post" block which consists of:
A content model (featuredPost) that contains:
title: A text string property.
post: A content picker property that allows for picking a blog post.
A settings model (featuredPostSettings) that contains:
backgroundColor: An approved color property.
showTags: A toggle property.
The goal is once again to build a condensed list of blog posts. But this time we'll build the list from the "Featured Post" blocks within each block editor.
To build the list we need the block title, the coverImage and excerpt from the picked post, and the backgroundColor from the block settings. Thus, we need to:
Expand the post property to retrieve the altText of the post coverImage.
Limit both the block-level properties and the nested post properties, as to only output the properties relevant for building the condensed list.
For comparison, the samples show both the default output and the output with expansion and limiting applied. Notice that:
The expand and fields parameter syntax is the same for all editors, even though their rendered output is structurally different.
The expand and fields parameters target both the content and settings parts of each block.
Default output without expansion and limiting:

}Property expansion and limiting is a powerful feature that can boost our application performance. With this, we can prevent additional requests to obtain data for linked items, and we can tailor the output to specific use cases.
However, it is also a complex feature. The query syntax quickly gets complicated, particularly when targeting block editors. You will likely need to experiment to get the query exactly right. Hopefully, the examples in this article will guide you in applying expansion and limiting to your own content.
