Issue & Transfer

to issue or issue+transfer SRR

POST <base_url>/port/api/v1/commerce/srrs

Please replace <base_url> as explained here.

Precaution

Multiple issuance

Feel free to include more than one issuance in a single request via the payload array. The minimum number of issue requests is one. Though there is no fixed upper limit for the number of issue requests you can submit at one time, we recommend limiting batches to no more than 250 issue requests for optimal processing.

issue to issuer

If payload[*].to is not given, your SRR will be issued to your luw address

Headers

Name	Type	Description
commerce-api-key*	string	Commerce API Key
issuer-address*	string	Contract Address of API Key owner

Request Body

Name	Type	Description
requestId	string	A requestId given by the caller, to ensure requests are only processed once. If the requestId is known and processed before, api will not process this call again, and respond with an error. A good practice is using random UUID. *requestId must be unique for a given issuer-address. As a result any duplicate combination of requestId and issuer-address is instantly rejected with no impact on either.
payload*	array	Array of issue requests. Further constraints explained above.
payload[*].externalId*	string	An ID to identify the record in your system. We recommend to use UUID, but it can use any string as long it is unique in your system.
payload[*].metadata*	object	The metadata to be issued as a complex object. Detailed schema specification can be found here. The API accepts versions 2.0 and higher.
payload[*].artistAddress*	string	The ethereum address of the artist of the artwork.
payload[*].isPrimaryIssuer*	boolean	If you are the primary issuer of this NFT, set this to true.
payload[*].lockExternalTransfer*	boolean	If you want to prevent your NFTs to be transferred on decentralized marketplaces, set this to true.
payload[*].to	string	Ethereum address target the NFT should be sent to after minting (Issue on Buyer). If none is given the NFT will be minted into your LUW by default.
payload[*].attachmentFiles	Array<object>	Attachment files that will be included in SRR.
payload[*].attachmentFiles[*].name	string	The name of file. This is used for when the file is downloaded or shown. The extension is recommended to be the same as the actual uploaded file.
payload[*].attachmentFiles[*].category	string	Please refer to this page to understand the difference among the categories. Please note that contract terms and thumbnail are NOT attachment files. The URL for contract terms and thumbnail are needed for metadata. (See metadata attribute)
payload[*].attachmentFiles[*].url	string	For the time being, the URL must be under Startbahn's GCS bucket. This can include finalUrl's that is the field in the response of the singed URL endpoint or a URL that has already been prepared for the client by Startbahn's team. Any other URL will result to rejecting the request without issuing the SRR
payload[*].collectionAddress	string	The address of collection that the SRR will belong to. This collection must be owned by the caller issuer-address.

201: Created

The API responds with 201. see Response Body results[*].status for details of each entry.

Body

Body Attribute	Description	Format
results	results of the request	Array
results[*].srr	Detail of the SRR. Please check example for detailed information.	object
results[*].externalId	ID to identify the SRR. Defined by client when calling.	string
results[*].status	waiting_for_miningwait for completion of blockchain mining. The status can be confirmed via subgraph or less favorably via this REST endpoint.	string

After a successful issuance, 2 types of JSONs will be returned in results[*].srr.metadata:

1. json

   It is converted from the originalJson. The object contains some values that are different from those that are written on chain. This json is meant to be easier for consumption on third party applications and it is maintained for backward compatibility. For example if an ipfs link exists in the metadata, this json converts it to an https link for easier consumption.

2. originalJson

   It is equal to what is written on chain. So if you want to consume this field, some carings are needed. For example it can contain ipfs links like ipfs:// that requires conversion before a browser can display it.

* both of the above JSONs may be different from what originally sent in the request payload.

Multiple issuance

In case of multiple/bulk issuance as soon as one case failed, the rest of the payload will be definitely failed as well.

Example of duplicated metadata

            }
        ]
    }
}

Example of DTO validation error

{
    "statusCode": 400,

        "payload.1.externalId should not be empty",
        "payload.1.externalId must be a string"
    ]
}

500: Internal Server Error

The API responds with 5xx if there are other issues, such as deeper validation errors.

Code Example

If you have a TAG for a physical artwork please add

chipUIDs and startbahnCertICTagUIDs both at the same time and they both need to contain the same value. The value is an array containing the list of the Chip UIDs. For example

"startbahnCertICTagUIDs": [
    "1234567890abcdef"
],
"chipUIDs": [
    "1234567890abcdef"
],
