3. Generate your publisher key and token

The detail steps at https://iotex.larksuite.com/docx/UawQd67JPopjqHxlSZmuV9HjsEh

Init the instance

Initialize the W3bstream instance with the URLs of your project, as shown below.:

import w3bstream
let url = "https://devnet-prod-api.w3bstream.com/srv-applet-mgr/v0/event/eth_0x2ee1d96cb76579e2c64c9bb045443fb3849491d2_get_nft_near_location"
let token = "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJQYXlsb2FkIjoiNjc3ODIwMjA4Mjc0MDIyNCIsImlzcyI6InczYnN0cmVhbSJ9.sN9pPsoRP-bRfKY2i1_qw9fRyigGRK6XT5osrdJbk7A"
let w3bStream = W3bStream(url: url, eventType: "DEFAULT", token: token)

Make the payload

Create the payload, the content is arbitrary. For example, we upload the designated location and the wallet address to receive the nft from the w3bstream service .

let timestamp = Int32(round(Date().timeIntervalSince1970))
let latitude = 36.702977661503
let longitude = 117.13273760933
let imei
let walletAddress = "0x2eE1d96CB76579e2c64C9BB045443Fb3849491D2"
        
var dic: [String: Any] = [
        "latitude": "\(latitude)",
        "longitude": "\(longitude)",
        "timestamp": timestamp,
        "imei": imei,
        "walletAddress": walletAddress
    ]
        
let payload = dic

Upload Data

Upload the payload data to your project on W3bstream using the upload method, as shown below:

w3bStream.upload(payload: payload, completionHandler: { data, err in
        if let json = try? JSONSerialization.jsonObject(with: data, options: []) as? [[String: Any]]{
        }
})

Check the result

Check the logs in the W3bstream website to view the payloads uploaded by your application. The uploaded payloads will be displayed there.
