How Can I Update the NFTs Metadata Using Alchemy’s NFT API?
Killiane MenandIf 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:
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.
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:
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.
