import SwiftUI
// STEP 1: Import SDK
import Candle

struct HomeView: View {
  @State var isAuthPresented = true
  @State var accounts: [Candle.LinkedAccount] = []
  @State var error: Candle.Error? = nil

  var body: some View {
    VStack(spacing: 16) {
      if let error {
          Text(error.localizedDescription)
      } else if accounts.isEmpty {
          Text("No accounts linked")
      } else {
        ForEach(accounts) { account in
          Text(account.name)
        }
      }
      Button(action: { isAuthPresented.toggle() }) {
        Text("Present Authentication")
      }.buttonStyle(BlackButtonStyle())
    }
    // STEP 2: Show Auth Flow
    .sheet(isPresented: $isAuthPresented) {
      Candle.LinkedAccountView(accounts: $accounts, error: $error)

Frequently Asked Questions

Data is never stored on our servers; instead, we route requests directly to the external service, preserving security standards and encryption. Candle’s SDK works just like the official app or website does.

Our SDK currently supports financial services like Robinhood, Cash App, Venmo, Apple Wallet, and more. Our grand vision is to be the only SDK you’ll need to connect to a service. If you need support for a specific one let us know or with us.

We generate a function-calling schema for every read and write request our SDK supports. These tools integrate directly into popular LLMs developed by OpenAI, Anthropic, Mistral, xAI, llama and more.
