Holdouts are experiments that reserve a portion of your traffic to measure the impact of your feature flags and experiments. They help establish a control group by excluding a percentage of users from seeing any experiments, allowing you to measure the overall impact of your experimentation program.  You can use query parameters to filter and sort the response. Holdouts can be in different states (draft, running, concluded) and can be scoped globally or locally within your project.
- [Create a new Holdout](https://docs.developers.optimizely.com/feature-experimentation/reference/create_holdout.md): Creates a new holdout experiment to establish a control group for measuring the impact of your feature flags and experiments.  A holdout reserves a percentage of your traffic (specified in basis points) that will be excluded from seeing any experiments, allowing you to measure the overall impact of your experimentation program against a baseline control group.  The holdout will be created in a `draft` status and can be configured with: - **Traffic allocation**: Percentage of users to exclude from experiments (0-10000 basis points) - **Scope**: Global (affects all experiments) or local (specific experiments only)   - **Audiences**: Target specific user segments using audience conditions - **Metrics**: Track and analyze the impact on key business metrics - **Environment**: Specify which environment the holdout applies to  **Key Validation Rules:** - Holdout `key` must be unique within the project - Required fields: `key`, `name` - `traffic_allocation` must be between 0-10000 (basis points) - `key` must match pattern: `^[a-zA-Z0-9_\-]+$` (max 64 characters) - `name` and `description` have character limits (255 and 1000 respectively)  **Metrics Integration:** If metrics are provided, they will be automatically saved to the MetricsHub for tracking and analysis.
- [Delete a Holdout](https://docs.developers.optimizely.com/feature-experimentation/reference/delete_holdout.md): Permanently and irreversibly delete a holdout by its unique ID. This is a destructive operation that cannot be undone.  **⚠️ CAUTION - Permanent Deletion:** - All holdout configuration data will be permanently lost - Associated metric data will be deleted from MetricsHub   - Experiment rules and historical data will be removed - There is **no way to recover** this data after deletion  **What gets deleted:** - Holdout configuration (traffic allocation, audience conditions, etc.) - All associated experiment rules and their settings - Metric tracking data and historical performance  - System metadata and lifecycle timestamps  **Safer Alternative - Archiving:** If you want to stop a holdout without permanent data loss, consider archiving instead: 1. Update the holdout status to `concluded` (if currently running) 2. Use the PATCH endpoint to set `archived: true`  Archived holdouts preserve all historical data while removing them from active lists and preventing further modifications.  **When to use DELETE vs ARCHIVE:** - **DELETE**: Use only when you're certain the holdout and all its data should be permanently removed - **ARCHIVE**: Recommended for most cases - preserves data for analysis while cleaning up active experiments  **Important Notes:** - Can delete holdouts in any status (draft, running, concluded) - Operation affects both database and MetricsHub systems - This corresponds to the `delete_url` link in holdout responses
- [Fetch a single Holdout](https://docs.developers.optimizely.com/feature-experimentation/reference/fetch_holdout.md): Retrieves detailed information about a specific holdout by its unique ID within a project.  **What you'll get:** - Complete holdout configuration including traffic allocation, status, and settings - Associated experiment rules and their current states   - Audience conditions and targeting criteria (if configured) - Metric tracking configuration and current values - Lifecycle timestamps (created, updated, started, ended) - RESTful links for related operations (update, delete, archive, etc.)  **Holdout States:** - **Draft**: Holdout is configured but not yet active - **Running**: Currently excluding traffic from experiments   - **Concluded**: Finished collecting data, results available for analysis  **Use Cases:** - View complete holdout configuration before making changes - Monitor current status and performance metrics - Access experiment rules affected by this holdout - Retrieve data for analysis and reporting - Verify permissions for management operations via included links  This operation corresponds to the `url` or `fetch_holdout_url` property found in holdout list responses.
- [Update a Holdout using JSON Patch](https://docs.developers.optimizely.com/feature-experimentation/reference/update_holdouts.md): Updates a specific holdout using JSON Patch operations (RFC 6902). This endpoint allows you to modify individual properties of an existing holdout without replacing the entire resource.  **Supported Operations:** - **Status transitions**: Move holdouts through their lifecycle (`draft` → `running` → `concluded`) - **Configuration updates**: Modify traffic allocation, name, description, and other settings - **Archive management**: Archive/unarchive concluded holdouts - **Metrics updates**: Modify metric configurations (restricted based on status)  **State Management & Validation Rules:** - **Draft holdouts**: All fields can be updated except readonly properties - **Running holdouts**: Limited updates allowed; cannot modify metrics or core configuration - **Concluded holdouts**: Only `name` and `archived` status can be modified - **Status transitions**: Must follow proper sequence (draft→running→concluded) - **Traffic allocation**: Must be 0-10000 basis points (0-100%)  **Automatic Timestamp Management:** - Moving to `running` status automatically sets `start_time` to current timestamp - Moving to `concluded` status automatically sets `end_time` to current timestamp  **Common Update Patterns:** ```json [   {"op": "replace", "path": "/name", "value": "Updated Holdout Name"},   {"op": "replace", "path": "/traffic_allocation", "value": 1500},   {"op": "replace", "path": "/status", "value": "running"} ] ```  **Important Limitations:** - Cannot modify metrics on running holdouts (prevents mid-experiment changes) - Cannot archive non-concluded holdouts (must conclude first) - Cannot update core configuration on running/concluded holdouts - ReadOnly properties in patch operations are ignored
- [Fetch experiments associated with a holdout](https://docs.developers.optimizely.com/feature-experimentation/reference/fetch_holdout_experiments.md): Retrieves a list of experiments that are connected to a specific holdout through the system's data relationships.  **What you'll get:** - **Experiment identification**: Layer experiment IDs from connected rules - **Timing information**: Start and end times from experiment reports   - **Variation details**: Deployed variation IDs when configured - **Clean data**: Filtered to remove empty or null values for clarity  **How experiments connect to holdouts:** This endpoint traverses complex database relationships to find experiments associated with a holdout: 1. **Holdout → Project**: Matches by project_id 2. **Project → Flags**: All flags in the same project 3. **Flags → Rulesets → Rules**: Rules within flag configurations 4. **Rules → Reports**: Experiment reports linked to rules 5. **Rules → Variations**: Deployed variations (when configured)  **Data relationships explained:** - Each returned experiment represents a rule that's potentially affected by the holdout's traffic allocation - Experiment timing comes from associated reports (start_time, end_time) - Deployed variations are included when rules have configured variations - Results are automatically filtered to exclude empty/null values  **Use cases:** - **Impact analysis**: Understanding which experiments are affected by a holdout - **Experiment coordination**: Viewing overlapping experiment timelines   - **Traffic allocation planning**: Seeing experiment relationships before making holdout changes - **Reporting integration**: Connecting holdout data with experiment performance - **Debugging**: Investigating unexpected experiment behavior related to holdouts  **Performance considerations:** - Query involves multiple table joins across the experiment system - Results are processed to remove empty values for cleaner responses - Response size depends on the number of connected experiments  This endpoint provides crucial visibility into the complex relationships between holdouts and the experiments they may influence.
