Update on a breaking change for the NFT-API v2.0, specifically for the token-type creation endpoint.

Updated Token-type creation request/response

Previously when creating a token-type, we passed an array in the request body. This method of creating a token-type will not work anymore as the request body is to be passed as an object.

Please look at the following examples where we compare the old way of creating a token-type (request body as an array) and the updated method where the request body is passed as an object.

Old method of creating a token-type

Request

🚧
The old method to create a token-type included passing the request body as an array.

Updated method of creating token-type

This example includes the updated request body (as an object) for creating a token-type and an updated response body.

The request body now includes a new array of objects called creations which includes information on a token-type. The creations array can include one or multiple token-type details, which means you can create one or multiple token-types with a single request.

When creating multiple token-types you can define them individually as objects within the creations array.

Request Endpoint: reference

 POST /api/v2/token-types/creations

Request Body:

Parameter	Description	Type	Required
`secretType`	The blockchain of the contract	String	✅
`contractAddress`	The contract address under which you want to create the token-type	String	✅
`creations`	An array of objects that can define one or multiple token-type details	Array of objects	✅
`creations.name`	The name of the token-type	String	✅
`creations.description`	The description of the token-type	String	❌
`creations.image`	The image URL for the token-type that will be displayed	String	❌

📘

The request body is an object.

The token-type details are passed in the creations array as object.

    }
  ]
}

Response Body:

📘

Save the result.creations.id from the response body. This is the token-type Creation ID and it's used to track the status of the token-type creation request.

The status attribute indicates the token-type creation status.

The result is now an object with an array of creations.
