NFT API for Generative Art Projects on DropKit

There are a few ways to get your metadata uploaded to NiftyKit so you can do your drop. Below we’ll show you how to POST your metadata directly using the REST API and your API key.

What you will need:

DropKit API key
HTTP/API client
Your final JSON data payload

DropKit API key

Each DropKit project has its own API key that is specific to that drop. To find the API key you will navigate to the 3-dot drawer menu in your DropKit dashboard page.

REST API endpoint

Each individual collection has a unique API key that allows you to submit your metadata via API.

You can access the API in the 3-dot drawer and copy your API key.

Using your API key, submit a POST request with the data to this endpoint.

POST https://app.niftykit.com/api/drops/tokens

You can reference the API documentation here.

HTTP/API Client

The easiest way to upload your JSON metadata to your DropKit project is using an HTTP/API Client with your API key from your NiftyKit account.

There are many free and paid HTTP/API Clients you can use.

We recommend these 2 free programs you can download:

Postman: https://www.postman.com/downloads/
Insomnia: https://insomnia.rest/download

For this tutorial we’ll be using Postman to send your JSON metadata to your DropKit project on NiftyKit.

Here are the steps to set up your API Client:

Add the POST URL
Add your API key
Paste in your JSON data in Body
Run the POST request

Add the POST URL

You can find the POST url inside the API key window in your project.

POST <https://app.niftykit.com/api/drops/tokens>

You will paste that in the request URL in Postman

Add your API key

Next, you will add your API key under the authorization section inside of the POSTMAN app.

Under the Headers tab you will need to add the key and value of your API key.

KEY: x-api-key
VALUE – this will be the API key you get in your DropKit project.

Paste in your JSON data in Body

Now that the POST url and API key is set, you can now add your JSON metadata to the BODY.

To start, you will need to have your images uploaded to IPFS and the metadata must be in JSON format with the proper values listed on our API. Click here to view the API docs for batch upload:

https://docs.niftykit.com/reference#create-drop-token-nft

There are different ways to get this data prepared. One of the most popular open source art generators is Hashlips Art Generator which can be found on github here:

https://github.com/HashLips/hashlips_art_engine

Once you are able to generate your data in the proper JSON format, you will need to paste that information directly in POSTMAN.

Below is an example metadata.json file generated by the Hashlips Art Generator. This array will need to be copied so we can paste it into POSTMAN.

Now that we have our JSON data ready, we need to make sure we format the data correctly when we run the POST inside of POSTMAN.

You can find an example inside the API window in your project in NiftyKit.

You need to make sure that you include and wrap the NFT information inside a data array. Using the code above that was generated by Hashlips Art Generator

You will paste the Hashlips generated data on line 2.

Run the POST Request

Once you run the request, you will see the NFTs show up inside your account
