Authentication
To use the FibriCheck API, there are two levels of authentication:
- Application authentication: your application needs to have credentials to communicate with FibriCheck
- User authentication: the end user needs to have proper credentials to authenticate against FibriCheck
FibriCheck supports OAuth 1.0 and OAuth 2.0 mechanisms for authentication and authorization of users.

When using OAuth 1.0, you need to add 2 sets of credentials to each request to the FibriCheck API:
- The Consumer Key and Consumer Secret, identify the application and are always required. We provide these credentials to you.
- The Access Token and Token Secret identify the user and are always required except for the user registration and authentication call. The authentication call that exchanges a e-mail/password combination for an Access Token and Token Secret is described below.
Keep in mind that an access token and token secret must always be used with the consumer key/secret they were generated with.
The remainder of this page discusses how to authenticate existing users, take a look here to learn more about registering new users.
Flutter
React Native
import 'package:flutter_fibricheck_sdk/flutter_fibricheck_sdk.dart';
// In this example we use the localstorage as a storage option for the credentials.
// Other packages or persistent storage methods can be used as well.
// More information: https://pub.dev/packages/localstorage
_storage = new LocalStorage('my_app');
_sdk = FLFibriCheckSdk.client("{consumerKey}", "{consumerSecret}");
void onConsentNeeded(List<Consent> documentsToSign) {
for (var document in documentsToSign) {
{
// 1. Request approval from the user
// 2. Pass the document back to the sdk
_sdk.giveConsent(document);
}
}
}
var res = await _sdk.authenticateWithEmail(
ParamsOauth1WithEmail(email: "{userEmail}", password: "{userPassword}"),
(consents) {
_onConsentNeeded(consents);
},
);
//save token
storage.setItem('token', res.token);
//save token secret
storage.setItem('tokenSecret', res.tokenSecret);
The
tokenData
information can be used to authenticate the user for subsequent API calls.
var res = await _sdk.authenticateWithToken(
ParamsOauth1WithToken(token: storage.getItem('token'), tokenSecret: storage.getItem('tokenSecret')), (consents) {
_onConsentNeeded(consents);
},)
In the following example we use
@react-native-async-storage/async-storage
to store the credentials. You are free to use any other storage option in your application. import AsyncStorage from '@react-native-async-storage/async-storage';
(async () => {
const sdk = client({
consumerKey: '',
consumerSecret: '',
});
// Function that handles required consents
const onConsentNeeded = (legalDocumentsUpdated: Consent[]) => {
legalDocumentsUpdated.forEach((document) => {
// 1. Request approval from the user
// 2. Pass the document back to the sdk
sdk.giveConsent(document);
});
};
const tokenData = await sdk.authenticate({
email: '',
password: '',
}, onConsentNeeded);
AsyncStorage.setItem('tokenData', JSON.stringify(tokenData));
})();
The
tokenData
information can be used to authenticate the user for subsequent API calls.import AsyncStorage from '@react-native-async-storage/async-storage';
(async () => {
const tokenDataString = await AsyncStorage.getItem('tokenData');
const tokenData = JSON.parse(tokenDataString);
await sdk.authenticate({
token: tokenData.key,
tokenSecret: tokenData.secret,
});
})();

Authenticate using OAuth 1.0
To implement the OAuth 1 protocol, additional parameters such as a request signature and nonce need to be added to the request. The FibriCheck Postman workspace contains an example request to authenticate successfully.
Also, libraries exist for each platform that facilitates performing OAuth 1.0 requests, for example node-oauth in the Node.JS ecosystem.
When you choose to authenticate via OAuth 2.0 (RFC 6749), you will receive a
clientId
and clientSecret
.Each of the API calls below are protected using the
client_secret_basic
method. The Authorization
header must be in the Basic: encodedString
format, where the encodedString
is a result of Base64 encoding of OAuth client’s clientId:clientSecret
.Password grant flow
{
"grant_type": "password",
"username": "{user_email}",
"password": "{user_password}"
}
Refresh token grant flow
After an initial login you can use the previously obtained refresh token to get a new token.
{
"grant_type": "refresh_token",
"refresh_token": "{refresh_token}"
}
The
access_token
in the result can be used to authenticate other calls using Bearer authentication.post

/auth/v2/oauth2/tokens
Get access tokens using the password grant flow
With every new access token, a new new refresh token is provided. Make sure to always store the latest refresh token.
Token Lifetime
The different OAuth2.0 tokens have a limited lifetime
- Access token: 5 minutes
- Refresh token: until used or until revoked
You can disable user authentication/access by removing their authentication tokens. This means that the user will be logged out and has to log in again to continue.
Execute an API call with the following payload to remove their authentication tokens:
{
"data": {
"command": "delete-authentication",
"data": {
"userId": "{userId}",
"groupId": "{groupId}"
}
}
}
