Managing Context Keys

Context keys are user-specific attributes that enable advanced targeting and segmentation in your AB Tasty feature experiments. They act as the data points passed from your application to AB Tasty to determine how features should behave for different audiences.

This guide shows how to view, create, and organize context keys using the AB Tasty FE&R interface.

Where to find context keys

From the left-hand sidebar, navigate to: Feature Experimentation → Context keys

This opens the Your context keys screen, listing all configured context keys.

Context key table overview

Each context key entry includes the following columns:

Column	Description
Name	Identifier for the context key (e.g., user_type, browser)
Type	Data type: STRING, BOOLEAN, or NUMBER
Description	Explanation of what the context key represents
Actions	Pencil icon to edit, trash icon to delete

You can also filter the list by type or use the search bar to find specific keys by name or description.

Creating a new context key

To create a new key:

1. Click the “Create key” button at the top right.

2. Fill in the following fields:

   • Name: Unique identifier for the key (e.g., user_is_premium)

   • Type: Select from STRING, BOOLEAN, or NUMBER

   • Description: Add a short explanation to help others understand the key’s purpose

3. Save the key.

It will now appear in the list and can be used in targeting rules for flags.

Editing a context key

To edit a context key:

1. Click the pencil icon next to the key you want to update.

2. Modify the name, type, or description as needed.

3. Save your changes.

Note: Changing the type of a context key used in active targeting may affect live campaigns.

Deleting a context key

To delete a context key:

1. Click the trash icon beside the key.

2. Confirm the deletion.

You should only delete keys that are no longer used in production environments or test configurations.

Filtering and searching context keys

You can use the filters above the list to view only:

• Boolean

• String

• Number

You may also use the search bar to quickly locate a specific key by name or description.

Best practices

• Use clear, descriptive names for keys to ensure consistency across teams.

• Add descriptions for documentation and easier maintenance.

• Avoid deleting keys that are actively used in live feature flags or experiments.

• Filter by type when troubleshooting or auditing targeting logic.
