Authorization

FACIA API relies on API keys for request authentication. You can conveniently view and manage your API keys in the FACIA Merchant Portal under account settings. Our API utilizes bearer authentication through Access Tokens and client-secret key authentication. It follows standard HTTP Status Codes and supports JSON/form-data Request and Response bodies. This comprehensive documentation thoroughly details each parameter, ensuring clarity and straightforward implementation.

Using the credentials created during registration, authentication can be performed based on:

1. Access Token
2. Client-secret key

Get Access Token

For authorization, Facia's SDKs require an Access Token with an expiration period of two days. You can obtain the Access Token using the following API through two methods:

1. Email and Password
2. Client-ID and Client-Secret Key

Endpoint

POSThttps://app.facia.ai/backend/api/transaction/get-access-token/

Request Samples:

1. Email and Password:

HTTP

//POST /api/transaction/get-access-token HTTP/1.1
//HOST : https://app.facia.ai/
//Content-Type: application/json

{
  "email": "your_email_here",
  "password": "your_password_here"
}

Javascript

var data = new FormData();
data.append("email", "your_email_here");
data.append("password", "your_password_here");

var xhr = new XMLHttpRequest();
xhr.withCredentials = true;

xhr.addEventListener("readystatechange", function() {
    if(this.readyState === 4) {
    console.log(this.responseText);
    }
});

xhr.open("POST", "/api/transaction/get-access-token");
xhr.send(data);

Request Parameter

Parameters	Description
email	Required: Yes Type: String
password	Required: Yes Type: String
client-id	Required without email: Yes Type: String
client-secret	Required without email: Yes Type: String

Sample Response

{
  "status": true,
  "message": "token",
  "result": {
    "data": {
      "token": "your_token_here"
    }
  }
}

Get Client Credentials

Using the credentials created during registration, make a request to the /get-client-credentials endpoint to obtain your unique client_id and client_secret key. The client_secret key (your unique API key) can be included in the headers to avoid generating a new access token every time.

Endpoint

POSThttps://app.facia.ai/backend/api/transaction/get-client-credentials

Request Samples:

HTTP

//POST /api/transaction/get-access-token HTTP/1.1 bearer token
//HOST :  https://app.facia.ai/

{
  "email": "your_email_here",
  "password": "your_password_here"
}
