# Ignoring elements

> Use x-fern-ignore to exclude endpoints, schemas, properties, or parameters from your OpenAPI spec. Control what Fern reads and processes.

If you want Fern to skip reading any endpoints, schemas, properties, or parameters, use the `x-fern-ignore` extension.

## Ignore an endpoint

To skip an endpoint, add `x-fern-ignore: true` at the operation level.

**`x-fern-ignore at operation level in openapi.yml`**

```yaml title="x-fern-ignore at operation level in openapi.yml" {4}
paths:
  /users:
    get:
      x-fern-ignore: true
      ...
```

## Ignore a schema

To skip a schema, add `x-fern-ignore: true` at the schema level.

**`x-fern-ignore at schema level in openapi.yml`**

```yaml title="x-fern-ignore at schema level in openapi.yml" {4}
components:
  schemas:
    SchemaToSkip:
      x-fern-ignore: true
      ...
```

## Ignore a property

To skip a property within a schema, add `x-fern-ignore: true` at the property level.

**`x-fern-ignore at property level in openapi.yml`**

```yaml title="x-fern-ignore at property level in openapi.yml" {9}
components:
  schemas:
    User:
      type: object
      properties:
        name:
          type: string
        internalField:
          x-fern-ignore: true
          type: string
```

## Ignore a parameter

To skip a parameter, add `x-fern-ignore: true` at the parameter level.

**`x-fern-ignore at parameter level in openapi.yml`**

```yaml title="x-fern-ignore at parameter level in openapi.yml" {7}
paths:
  /users:
    get:
      parameters:
        - name: internalParam
          in: query
          x-fern-ignore: true
          schema:
            type: string
```

To skip a parameter without modifying your base spec, use `null` values in your [overrides file](/learn/api-definitions/openapi/overrides) to delete parameters:

**`overrides.yml`**

```yaml title="overrides.yml" {5}
paths:
  /users:
    get:
      parameters:
        - null  # Deletes the first parameter from base spec
```
