I am trying to create a product verification system, and I have the login part down. My question is how are there any API (s) that can verify something like an activation code and return if it succeeded or not. Btw, you might have to scroll horizontally to see all of the code
//How would I add a verification system
document.getElementById('redeemButton').addEventListener('click', () => {
var code = document.getElementById('redeemCodeBox').value;
var product = document.getElementById('productCode').value;
const fetchPromise = fetch(`https://www.mywebsite.com/api/redeem?product=${product}&code=${code}`);
fetchPromise.then( response => {
if (!response.ok) {
throw new Error(`HTTP error: ${response.status}`);
}
return response.json();
})
.then( json => {
console.log(json[0].name);
})
.catch( error => {
console.error(`Could not get products: ${error}`);
throw `Please Enter a Valid Activation Code`;
});
});
I don't think you should be dependent on a third party to verify an Activation Code.
You should use a combination of JWT token + activation code that you store in the database.
Generate an activation code.
Generate JWT token.
const token = await this.jwtService.sign( { usetId: userId }, { expiresIn: "1d" } );
Save the activation code and the JWT token to the database.
Send an E-mail or SMS with an activation code to the user. + include URL where user can insert the activation code.
URL can look something like this:
https://www.mywebsite.com/api/activation?token=eyJhbGciOiJIfasdfas
(use query parameter for JWT token =>> ?token=JWT_token
Verify JWT token from URL (value from query parameter "token") and validate if Token is not expired.
Control if user input matches an Activation code stored in your database.
