Intro

There are three basic things that you can change in an NFT.

Attributes:
1. Type of attribute
2. Name of the attribute
3. Attribute's value
4. Attribute's maximum value
Properties:
1. Name
2. Description
3. External Url
4. Image
5. Background Color
Animation URLs

📘

Changes made on the token-level will not affect anything on the token-type level. The token-type will have the same metadata as you defined when creating it.

If you change the metadata of the token-type, after minting an NFT, the changes will not reflect in the already minted NFT. The changes will reflect only on the new minted NFTs under that token-type.

Dynamic NFT Endpoints

Following is an example of an already-minted NFT. We will use this and update its properties, attributes, and animation URLs, all on the token level.

1. Attributes

Attributes on the token level can be updated, added, and deleted. Read more about attributes.

You can change (add, update, delete) attributes on the token-level without affecting the attributes defined on the token-type level. When you change an attribute, it is only for a specific NFT.

All NFTs minted from a token-type will include the original attribute values that were defined when you created the token-type. In short, the changes will not affect the token-type.

🚧
As there can be multiple attributes, the attributes defined on the token-type level will be merged together with attributes defined on the token level.

1.1 Update Attribute

You can update an attribute's data for a specific NFT using the following endpoint.

🚧
The attributes tokenTypeId, maxSupply, mintNumber cannot be updated.

2. Properties

The following properties on the token level can be updated, added, and deleted:

name (This property cannot be deleted)
description
externalUrl
image
backgroundColor

🚧
As all the properties can only have a single value, the changes made to properties on token level will overide the properties defined on the token-type level.

2.1 Update a Property

You can update a property for a specific NFT using the following endpoint.

📘
You can also use this endpoint to add a property, such as name, description, externalUrl, image, backgroundColor.

Request Endpoint: reference

PUT /api/v3/erc1155/contracts/{chain}/{contractAddress}/tokens/{tokenId}/metadata/{propertyName}

Parameter	Param Type	Description	Type	Required
`{chain}`	Path	The blockchain of the NFT collection	String	✅
`{contractAddress}`	Path	The NFT contract address	String	✅
`{tokenId}`	Path	The `ID` of the token you want to update	String	✅
`{propertyName}`	Path	The name of the property you want to update (NOTE: This param is case sensitive.) This can be: `name, description, externalUrl, image, backgroundColor`	String	✅
`value`	Body	Value of the property that you want to update	String	✅

Example Request

📘
We are going to change the value of the description property. In our original minted NFT, the description property had the value:
    "description": "Dynamic NFTs"

3. Animation Url

The animation Urls on the token level can be updated, added, and deleted. Read about [animationUrls](https://docs.venly.io/docs/animation-media#animationurls).

🚧

The animationUrls is a single array. The changes made to it on the token level will overide the animationUrls defined on the token-type level.

When you update the animationUrls, you will overwrite the whole array of URLs, thus you cannot update one specific URL from the array.

3.1 Update Animation URL

You can update the animationUrls for a specific NFT using the following endpoint.

📘

This endpoint can also be used to add the animationUrls, in case you delete them.

Running this endpoint will overwrite the previous animationUrls array.

Request Endpoint: reference

PUT /api/v3/erc1155/contracts/{chain}/{contractAddress}/tokens/{tokenId}/metadata/animationUrls

Parameter	Param Type	Description	Type	Required
`{chain}`	Path	The blockchain of the NFT collection	String	✅
`{contractAddress}`	Path	The NFT contract address	String	✅
`{tokenId}`	Path	The `ID` of the token you want to update	String	✅
`type`	Body	The type of the animation media. Allowed values: `image \| audio \| video`	String	✅
`value`	Body	The URL of the animation media	String	✅

Example Request

📘
