# Update segment

> Update an existing segment.

<Warning>
  The Resend Go SDK does not currently provide an Update method for segments. To modify a segment, you'll need to delete the existing segment and create a new one with the updated information.
</Warning>

## Alternative approach

To update a segment, follow these steps:

1. Use the [Get segment](/api-reference/segments/get) method to retrieve the current segment details
2. Use the [Delete segment](/api-reference/segments/delete) method to remove the existing segment
3. Use the [Create segment](/api-reference/segments/create) method to create a new segment with updated information

## Example

```go theme={null}
package main

import (
    "fmt"
    "github.com/resend/resend-go/v2"
)

func main() {
    client := resend.NewClient("re_123456789")

    // Get the current segment
    segment, err := client.Segments.Get("seg_123456")
    if err != nil {
        panic(err)
    }

    // Delete the existing segment
    _, err = client.Segments.Remove("seg_123456")
    if err != nil {
        panic(err)
    }

    // Create a new segment with updated name
    params := &resend.CreateSegmentRequest{
        Name: "Updated Segment Name",
    }

    newSegment, err := client.Segments.Create(params)
    if err != nil {
        panic(err)
    }

    fmt.Println("New Segment ID:", newSegment.Id)
}
```

<Info>
  Note that this approach will change the segment ID. Make sure to update any references to the old segment ID in your application.
