The bank system api is a REST API implemented with node js, express and mongodb. The api enables a user to do do the following:
- Create an account
- Add funds to their accounts
- Transfer funds to another user's account
- Withdraw funds from their account
- Check account balance
- Create account: api to posted
- AddFunds: api to be posted
- Transfer funds: api to be posted
- Withdraw funds: api to posted
- Get all accounts in the bakn: api to be posted
- Get account balance
You can use any method to fetch data from the api
Before you use the api you must signup so as to recieve an authentication token that will be used to create an account and during transactions. Sign up using name, date of birth and pin(string)
fetch("api to be posted", {
method: "POST",
body: JSON.stringify({
name: "Izolah Machengiator",
brth: "10 may 1998",
pin: "mypin",
}),
})
.then((res) => res.json())
.then((json) => console.log(json));
/* response
{
"user": {
"name": "Izolah Machengiator",
"birth": "10 may 1998",
"pin": "$2a$10$8tfcNuDBvavokOR7HaIh0uOJ0ACF0drd8JMDeBPwEKr7.75uHsHSG",
"_id": "63e3fc240a03ad3a11d90258",
"__v": 0
},
"token": "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJfaWQiOiI2M2UzZmMyNDBhMDNhZDNhMTFkOTAyNTgiLCJpYXQiOjE2NzU4ODU2MDUsImV4cCI6MTY3NjA1ODQwNX0.y6dF75gBdvXYpd-qPLWClY5R1pctZoiGtaQjtrdN_3U"
}
*/Since the authentication tokens expire after some specified period of time you will need to signin to get an acces token to use during transactions. Sign in using your pin(string) only
fetch("api to be posted", {
method: "POST",
body: JSON.stringify({
name: "Izolah Machengiator",
pin: "mypin",
}),
})
.then((res) => res.json())
.then((json) => console.log(json));
/* response
{
"user": {
"_id": "63e3fc240a03ad3a11d90258",
"name": "Izolah Machengiator",
"birth": "10 may 1998",
"pin": "$2a$10$8tfcNuDBvavokOR7HaIh0uOJ0ACF0drd8JMDeBPwEKr7.75uHsHSG",
"__v": 0
},
"token": "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJfaWQiOiI2M2UzZmMyNDBhMDNhZDNhMTFkOTAyNTgiLCJpYXQiOjE2NzYxNDIyOTcsImV4cCI6MTY3NjMxNTA5N30.Schi1_bcpVdbk4OuaeCzmIj6XWd38PFxDso2Cj7Keag"
}
*/After signing in to the bank you have to ceate an account for you to be able to make transactions. You need to have an authentication token(json web token) to be able to create your account, this helps in identifying who is creating the account.
fetch("api to be posted", {
method: "POST",
body: JSON.stringify({
accountType: "savings",
}),
})
.then((res) => res.json())
.then((json) => console.log(json));
/* response

"isSaved": {
"user": "63e3fc240a03ad3a11d90258",
"balance": 100,
"_id": "63f0f010175b47012ba784ac",
"__v": 0
},
"response": "Account created succesfully"
}
*/fetch("api to be posted", {
method: "POST",
body: JSON.stringify({
balance: 2000,
}),
})
.then((res) => res.json())
.then((json) => console.log(json));
/* response
{
"newAmnt": {
"acknowledged": true,
"modifiedCount": 1,
"upsertedId": null,
"upsertedCount": 0,
"matchedCount": 1
},
"response": "You have succesfully deposited $ 2000 in your account"
}
*/if you get this response then, the funds have been succesfully deposited to your account
fetch("api to be posted", {
method: "POST",
body: JSON.stringify({
balance: 2000,
}),
})
.then((res) => res.json())
.then((json) => console.log(json));
/* response
{
"newAmnt": {
"acknowledged": true,
"modifiedCount": 1,
"upsertedId": null,
"upsertedCount": 0,
"matchedCount": 1
},
"response": "You have succesfully withdraw $ 2000 from your account"
}
*/For transfering of fund you need too have the id of source of the funds(sender) and the id of the reciever of the funds. senders id: we shall get it from req.params reciever id: we shall get it from req.query note: I think there are more efficient and simple way to do this but this is how i did it but am also working to get a more efficient way to do it.
fetch("api to be posted", {
method: "POST",
body: JSON.stringify({
balance: 2000, //amount to be sent
}),
})
.then((res) => res.json())
.then((json) => console.log(json));
/* response
{
"recieverNewBal": {
"acknowledged": true,
"modifiedCount": 1,
"upsertedId": null,
"upsertedCount": 0,
"matchedCount": 1
},
"updatedBal": {
"acknowledged": true,
"modifiedCount": 1,
"upsertedId": null,
"upsertedCount": 0,
"matchedCount": 1
},
"response": "You have succesfully transfered $ 2000"
}
*/You can get the account balance by sending a get request
fetch("api to be posted", {
method: "GET",
})
.then((res) => res.json())
.then((json) => console.log(json));
/*

}
*/fetch("api to be posted", {

})
.then((res) => res.json())
.then((json) => console.log(json));
