This endpoint updates the value of a Feature Flag or Setting with a collection of operations in a specified Environment.
Only the value, rolloutRules and percentageRules attributes are modifiable by this endpoint.
The advantage of using JSON Patch is that you can describe individual update operations on a resource without touching attributes that you don't want to change. It supports collection reordering, so it also can be used for reordering the targeting rules of a Feature Flag or Setting.
For example: We have the following resource.
If we send an update request body as below:
Only the default value is going to be set to true and all the Percentage Rules are remaining unchanged.
So we get a response like this:
The rolloutRules property describes two types of rules:
- Targeting rules: When you want to add or update a targenting rule, the
comparator,comparisonAttribute, andcomparisonValuemembers are required. - Segment rules: When you want to add add or update a segment rule, the
segmentIdwhich identifies the desired segment and thesegmentComparatormembers are required.
