## Insert Vectors

`client.Vectorize.Indexes.Insert(ctx, indexName, params) (*IndexInsertResponse, error)`

**post** `/accounts/{account_id}/vectorize/v2/indexes/{index_name}/insert`

Inserts vectors into the specified index and returns a mutation id corresponding to the vectors enqueued for insertion.

### Parameters

- `indexName string`

- `params IndexInsertParams`

  - `AccountID param.Field[string]`

    Path param: Identifier

  - `Body param.Field[Reader]`

    Body param: ndjson file containing vectors to insert.

  - `UnparsableBehavior param.Field[IndexInsertParamsUnparsableBehavior]`

    Query param: Behavior for ndjson parse failures.

    - `const IndexInsertParamsUnparsableBehaviorError IndexInsertParamsUnparsableBehavior = "error"`

    - `const IndexInsertParamsUnparsableBehaviorDiscard IndexInsertParamsUnparsableBehavior = "discard"`

### Returns

- `type IndexInsertResponse struct{…}`

  - `MutationID string`

    The unique identifier for the async mutation operation containing the changeset.

### Example

```go
package main

import (
  "bytes"
  "context"
  "fmt"
  "io"

  "github.com/cloudflare/cloudflare-go"
  "github.com/cloudflare/cloudflare-go/option"
  "github.com/cloudflare/cloudflare-go/vectorize"
)

func main() {
  client := cloudflare.NewClient(
    option.WithAPIToken("Sn3lZJTBX6kkg7OdcBUAxOO963GEIyGQqnFTOFYY"),
  )
  response, err := client.Vectorize.Indexes.Insert(
    context.TODO(),
    "example-index",
    vectorize.IndexInsertParams{
      AccountID: cloudflare.F("023e105f4ecef8ad9ca31a8372d0c353"),
      Body: io.Reader(bytes.NewBuffer([]byte("Example data"))),
    },
  )
  if err != nil {
    panic(err.Error())
  }
  fmt.Printf("%+v\n", response.MutationID)
}
```
