Developer Questions

Could someone help with some python code (xumm.sdk) to create an offer on a NFT? I tried re-working the sample codes with no luck.

PS C:\\Users\\socia> node "C:\\Users\\socia\\Desktop\\XRPL-DEXBot-main\\deploy-commands.js" C:\\Users\\socia\\node_modules\\xumm-sdk\\dist\\src\\Meta.js:51 throw new Error('Invalid API Key and/or API Secret. Use dotenv or constructor params.');

hey team we are trying to integrate XUMM for our website in web browser. we need to sign a customised hash in order to go through. however the following code does not wake up any QR code process. Can you help give some idea? Thanks const subscription = await this.xumm.payload.createAndSubscribe({ custom_meta: { instruction: hash.hash, }, txjson: { TransactionType: "SignIn", } }, event => { console.log('New payload event:', event.data) if (event.data.signed === true) { console.log(event.data.payload_uuidv4) console.log('Woohoo! The sign request was signed :)') this.doLogin(event.data.payload_uuidv4, userAccount,hash) return event.data } ``` if (event.data.signed === false) { console.log('The sign request was rejected :(') this.closeHandle() return false } }) ```

Hey, community members, I need help on creating xumm payload with nft-metadata. Here is the payload I'm currently using for minting: payload_data = { ``` form = NFTForm(request.POST, request.FILES, initial={ 'xrpl_data': xrpl_data_json}) print(form) if form.is_valid(): title = form.cleaned_data['title'] description = form.cleaned_data['description'] image = form.cleaned_data['image'] payload_data = { "txjson": { "TransactionType": "NFTokenMint", "Account": publicAddress, "URI": ipfs_cid, "Flags": 8, "TransferFee": 10, "NFTokenTaxon": 0 }, "options": { "return_url": { "web": "http://127.0.0.1:8000/XummMintCallbackView" } }, "metadata": { "name": title, "description": description } } ``` So, please let me know if there is any alternate way to handle the metadata or if is there any standard format for payload_data to include the metadata for the MintNFToken transaction.

Hello fellow forum members, I'm a python/django developer, looking for assistance in creating NFTs using XUMM. I'm interested in the entire process, from minting to listing these non-fungible tokens on the blockchain(XRPL). Any kind of code snippit you can provide will be greatly appreciated! Could someone kindly provide a step-by-step guide or offer any tips, resources, or recommendations to help me get started with this exciting venture? Your expertise would be greatly appreciated! Thank you in advance.

``` if (process.argv.length < 3) { console.log('usage: node dist/index <secret_type> <secret> <destination> <amount>'); console.log ("secret type\n1. family\n2.

Hello XUMM Developer Community, I hope this message finds you well. I am currently working on implementing user authentication in my Python/Django application using XUMM. I have made progress up to the point where users can successfully sign in by scanning a barcode.  However, I am encountering an issue where the user cannot be redirected to my website upon successful sign-in. I would greatly appreciate your assistance in resolving this issue. If you have any experience or insights into how to properly handle the redirection after a successful sign-in using XUMM in a Django application, I would be very grateful for your guidance. Any advice, code snippets, or best practices you can share would be incredibly valuable to me and my project. Thank you in advance for your help and support. I look forward to hearing from you and learning from your expertise. Best regards, Varun Kumar
