# How can I update the NFTs metadata using Alchemy’s NFT API?

If you need to update the metadata for all the NFTs in your contract or for a specific NFT, Alchemy offers methods that allow you to refresh this data easily. Please note that the `reingestContract` method is being replaced by the new `invalidateContract` method. Below are the steps you can follow to update your NFT metadata.

## How do I update metadata for all NFTs in a collection?
To update the metadata for every NFT in your contract, you can use the `invalidateContract` method. This method will re-fetch and update the metadata for all tokens under the specified contract.

Example `invalidateContract`** Call:**

```bash
curl --request GET \
     --url 'https://eth-mainnet.g.alchemy.com/nft/v3/docs-demo/invalidateContract?contractAddress=0xe785E82358879F061BC3dcAC6f0444462D4b5330' \
     --header 'accept: application/json'
```

Simply replace the `contractAddress` parameter with the address of your own contract. For more detailed information, please refer to the [API documentation for the invalidateContract method](https://www.alchemy.com/docs/reference/nft-api-endpoints/nft-api-endpoints/nft-metadata-endpoints/invalidate-contract-v-3).

## How do I update metadata for a specific NFT?
If you want to refresh the metadata for just one specific NFT, you can use the `getNFTMetadata` method with the `refreshCache` parameter set to true. This will force the metadata to be refreshed for that individual token.

Example `getNFTMetadata`** Call:**

```bash
curl --request GET \
     --url 'https://eth-mainnet.g.alchemy.com/nft/v3/docs-demo/getNFTMetadata?contractAddress=0xe785E82358879F061BC3dcAC6f0444462D4b5330&tokenId=44&refreshCache=false' \
     --header 'accept: application/json'
```

Replace `contract\_address` with your contract’s address and `token\_id` with the token ID of the specific NFT you want to refresh.

## Why is my reingestContract** request stuck on “in progress”?**

The `reingestContract` method is being replaced by the `invalidateContract` method, which offers a more reliable way to update NFT metadata. If you are experiencing issues with `reingestContract`, we recommend switching to `invalidateContract` for better results.
