# Updating Mapper

The `update_mapper()` method in **Cataloglake** allows users to update metadata mappings associated with specific accounts in the catalog. This operation helps in aligning and modifying metadata attributes dynamically for better data handling and consistency.

**Payload Example**

```python
update_mapper_payload={
    "groc_account_id": "c4ca4238a0b923820dcc509a6f75849b",
    "metadata_mapper_id": "36769c86-c320-4539-a073-f9f9319977f6",
    "metadata_keymap": [
        {
            "address of manufacturer": "manufacturer_address",
            "fssai number": "fssai_number",
            "marketing_fssai_num": "marketing_fssai_number",
            "fabric_colour": "colour",
            "new_map": "fssai_number",
            "new_address of manufacturer": "fssai_number"
        }
    ]
}

```

Usage example

```python
update_mapper = cataloglake.update_mapper(upadate_mapper_payoad)
print(update_mapper)
```

Example Response

```json
{
  "message": "Mapping updated successfully.",
  "mapping": {
    "metadata_mapper_id": "36769c86-c320-4539-a073-f9f9319977f6",
