Just an update. Using this on the mainnet now and totally love it!
One thing, I dont see a buy action available?
Also, are some of the other sdk functions coming down the road?
Oh! I went back through each demo page and realized Buy is part of the Accept Order action!

Absolutely, we are working on it. 
Use the Accept Order action
Hi @ezdev , thanks so making this plugin, appreciate all your work as always. Any plan to add the ability to mint like with your Rarible plugin? If yes, any timeline to share? Thanks.
So far, OpenSea SDK does not provide minting functionality. You could still do that combining it with the Rarible SDK.
So, use the Rarible for minting, and OpenSea for everything else.
Yes, I am aware of that. My worry is related to secondary royalties. I read that royalties arenât cross-plateform. For example, if you use Rarible shared smart contract where you set your royalties %, whenever the NFT is sold on OpenSea, you wonât get any royalties.
I was thinking of using a service like https://niftykit.com/ to create my custom smart contract which would allow me to mint all my NFT under my own custom collection unlike the way itâs done currently as someone in Rarible plugin forum pointed out, use your Rarible plugin to mint my NFT under my custom contract.
But I doubt that the royalties payement will be cross-platform even with my custom contract, especially since Opensea caps royalties at 10% VS Rarible at 30%.
What do you think would happen with a custom contract?
I donât know how niftykit works, but, usually doing a custom smart contract is the best way, since you can set your own rules and any royalties you want directly in contract.

Hi @ezdev , I see you have the âGet asset Eventsâ included in your plugin. When I test this API endpoint here on Opensea, I get an error 403 error. It seems that Cloudflare is restricting access, some guy in a forum suggested that this endpoint isnât opened to the public yet.
Were you able to get a 200 status calling asset events with your plugin?
Interesting, it was opened at the stage of creating the plugin, Iâll remove it until they will open it again.

Hi just to be sure i understand the functionality of Opensea SDK
We need to mint the NFT on Opensea website and then we can sell / transfert etc directly in our webapp, right?
Opensea SDK allows you to sell/bid/transfer but not minting.
For minting you can use the free plugin Rarible SDK
But if i mint on Rarible, how can i then sell in on Opensea? (Im on Polygon btw, not ETH)
In the end it doesnât matter where do you mint, tokens are visible on all platforms, thatâs the cool thing about NFTs, however Rarible doesnât support Polygon at the moment.
So, in this case, you will need your own smart contract on Polygon and mint tokens using standard tools from the Web3 plugin.
So, just to be sure i have understood everyting, can i follow the below procedure?
⢠Mint my Polygon NFT directly on Opensea
⢠Make them available to view / sell / buy on my webapp thanks to Opensea SDK and Web3 Plugin
Am i right or am i missing anything?
Thanks for your help!
If you will mint it directly on Opensea, then yes, you can do everything else with the plugins directly in your app.
You can do tests on Rinkeby network firts
Ok its clear thanks , I wanted to try on Rinkeby but im struggling to have Faucet ETH so iâm working on Polygon as fees are very cheap
Just one last point, once I have minted my NFT on Opensea, how can i get all the info on my Webapp (ie IPFS, Description, Blockchain, owners (there is several owners as it is a ERC1155 Token) ? I have seen the âNFT Metadataâ option on the Metamask Web3 plugin but I not sure i can get all the required data through it
Thanks!
Send me your wallet in PM, Iâll send you some test ETH.
The NFT Metadata is used to show the image, name and description.
To get owners you can use the Web3 plugin as well with action Read Contract, and use the smart contract functions that correspond to token type, for example ownerOf or something. like that.
Alternatively you can use OpenSea API or again, Rarible SDK but the Rarible is not available on Polygon network.
All your responses are very helpful, thanks. I will have a look at the Opensea API
So with Metamask Web3, once I have a specific contract / token ID, how can i interact with the SDK to have others info ?
Check demo page, there are a lot of example with each action 
You will find there a link to app editor to see how it works from the inside.
Hey on the Opensea API, seems like it can only be used through ETH Mainnet and Web3 Metamask only with ERC721 Token . Is there a solution to interact with semi fungible token on Polygon?
