JS Code

import { LiteInlineCheckout } from "tonder-web-sdk";

const apiKey = "your-api-key";
const returnUrl = "http://your-website.com/checkout";

const liteCheckout = new LiteInlineCheckout({
  mode: "development",
  apiKey,

});

liteCheckout.configureCheckout({ customer: { email: "example@email.com" } });
liteCheckout.injectCheckout();

liteCheckout.verify3dsTransaction().then((response) => {
  console.log("Verify 3ds response", response);
});

document
  .getElementById("lite-payment-form")

    event.preventDefault();
    const cardData = {
      card_number: document.getElementById("card-number").value,
      cardholder_name: document.getElementById("card-name").value,
      expiration_month: document.getElementById("month").value,
      expiration_year: document.getElementById("year").value,
      cvv: document.getElementById("cvv").value,
    };

    try {
      const paymentData = { ...checkoutData, card: cardData };
      const response = await liteCheckout.payment(paymentData);
      console.log("Payment response:", response);
      alert("Payment successful");
    } catch (error) {
      console.error("Payment error:", error);
      alert("Payment failed");
    }
  });
For React or Nextjs applications, we recommend using a context provider to manage the Tonder instance across your application.
1

Create a Tonder Provider

// TonderProvider.jsx
"use client"; // only for Nextjs
import React, { createContext, useContext, useState, useEffect } from "react";
import { InlineCheckout } from "tonder-web-sdk";

const TonderContext = createContext();

export const useTonder = () => useContext(TonderContext);

export const TonderProvider = ({ children }) => {
  const [tonderInstance, setTonderInstance] = useState(null);

  useEffect(() => {
    const init = async () => {
      try {
        const inlineCheckout = new InlineCheckout({
          mode: "development",
          apiKey: "your-api-key",
          returnUrl: "http://your-website.com/checkout",
        });
        setTonderInstance(inlineCheckout);
      } catch (error) {
        console.error("Error initializing Tonder:", error);
      }
    };

    init();
  }, []);

  return (
    <TonderContext.Provider value={tonderInstance}>
      {children}
    </TonderContext.Provider>
  );
};
2

Create the TonderCheckout Component

// TonderCheckout.jsx
"use client"; // only for Nextjs
import React, { useEffect, useState } from "react";
import { useTonder } from "./TonderProvider";

const TonderCheckout = () => {
  const tonder = useTonder();
  const [loading, setLoading] = useState(false);

  useEffect(() => {
    if (!tonder) return;

    tonder.configureCheckout({ customer: { email: "example@email.com" } });
    tonder.injectCheckout();

    tonder.verify3dsTransaction().then((response) => {
      console.log("Verify 3ds response", response);
    });

    return () => {
      if (tonder.removeCheckout) {
        tonder.removeCheckout();
      }
    };
  }, [tonder]);

  const handlePayment = async () => {
    if (!tonder) return;
    setLoading(true);
    try {
      const response = await tonder.payment(paymentData);
      console.log("Payment successful:", response);
      alert("Payment successful");
    } catch (error) {
      console.error("Payment failed:", error);
      alert("Payment failed");
    } finally {
      setLoading(false);
    }
  };

  return (
    <div>
      <div id="tonder-checkout"></div>
      <button onClick={handlePayment} disabled={loading}>
        {loading ? "Processing..." : "Pay Now"}
      </button>
    </div>
  );
};

export default TonderCheckout;
3

Use the TonderCheckout

"use client"; // only for Nextjs
import { useEffect, useState } from "react";
import { useTonder, TonderProvider } from "./TonderProvider";
import Script from "next/script";

export default function TonderCheckout() {
  return (
    <div id="checkout">
      {/*Provider*/}
      <TonderProvider>
        <CheckoutContent />
      </TonderProvider>
    </div>
  );
}

function CheckoutContent() {
  const tonder = useTonder();
  const [loading, setLoading] = useState(false);

  useEffect(() => {
    if (!tonder) return;
    tonder.configureCheckout({ customer: { email: "example@email.com" } });
    tonder.injectCheckout();
    tonder.verify3dsTransaction().then((response) => {
      console.log("Verify 3ds response", response);
    });
    return () => {
      if (tonder.removeCheckout) {
        tonder.removeCheckout();
      }
    };
  }, [tonder]);

  const handlePayment = async () => {
    if (!tonder) return;
    setLoading(true);
    try {
      const response = await tonder.payment(paymentData);
      console.log(response);
      alert("Payment successful");
    } catch (error) {
      console.error(error);
      alert("Payment failed");
    } finally {
      setLoading(false);
    }
  };

  return (
    <div>
      <div id="tonder-checkout"></div>
      <button onClick={handlePayment} disabled={loading}>
        {loading ? "Processing..." : "Pay"}
      </button>
    </div>
  );
}
For Angular, we recommend using a service to manage the Tonder instance:
// tonder.service.ts
import { Injectable } from "@angular/core";
import { InlineCheckout } from "tonder-web-sdk";

@Injectable({
  providedIn: "root",
})
export class TonderService {
  private inlineCheckout: InlineCheckout;

  constructor(private sdkParameters: IInlineCheckoutOptions) {
    this.initializeInlineCheckout();
  }

  private initializeInlineCheckout(): void {
    this.inlineCheckout = new InlineCheckout({ ...this.sdkParameters });
  }

  configureCheckout(customerData: IConfigureCheckout): void {
    this.inlineCheckout.configureCheckout({ ...customerData });
  }

  async injectCheckout(): Promise<void> {
    await this.inlineCheckout.injectCheckout();
  }

  verify3dsTransaction(): Promise<ITransaction | void> {
    return this.inlineCheckout.verify3dsTransaction();
  }

  // Add more functions, for example for lite sdk: get payment methods

  // getCustomerPaymentMethods(): Promise<IPaymentMethod[]> {
  //     return this.liteCheckout.getCustomerPaymentMethods();
  // }
}

// checkout.component.ts
import { Component, OnInit, OnDestroy } from "@angular/core";
import { TonderService } from "./tonder.service";

@Component({
  selector: "app-tonder-checkout",
  template: `
    <div id="tonder-checkout"></div>
    <button (click)="pay()" [disabled]="loading">
      {{ loading ? "Processing..." : "Pay" }}
    </button>
  `,
  providers: [
    {
      provide: TonderInlineService,
      // Inicialización del SDK de Tonder Inline
      // Nota: Reemplace estas credenciales con las suyas propias en desarrollo/producción
      useFactory: () =>
        new TonderInlineService({
          apiKey: "11e3d3c3e95e0eaabbcae61ebad34ee5f93c3d27",
          returnUrl: "http://localhost:4200/checkout/payment?tabPayment=0",
          mode: "development",
        }),
    },
  ],
})
export class TonderCheckoutComponent implements OnInit, OnDestroy {
  loading = false;

  constructor(private tonderService: TonderService) {}

  ngOnInit() {
    this.initCheckout();
  }

  ngOnDestroy() {
    // Limpieza del checkout al destruir el componente
    this.tonderService.removeCheckout();
  }

  async initCheckout() {
    this.tonderService.configureCheckout({
      customer: { email: "example@email.com" },
    });
    await this.tonderService.injectCheckout();
    this.tonderService.verify3dsTransaction().then((response) => {
      console.log("Verify 3ds response", response);
    });
  }

  async pay() {
    this.loading = true;
    try {
      const response = await this.tonderService.payment(paymentData);
      console.log("Payment successful:", response);
      alert("Payment successful");
    } catch (error) {
      console.error("Payment failed:", error);
      alert("Payment failed");
    } finally {
      this.loading = false;
    }
  }
}
