ASM Application Authentication

The Authentication API is used to generate an Access Token, which is required for all API calls that require authentication.

Token Validity and Usages

IMPORTANT:

• The Access Token obtained from this API call remains valid for 1 hours.
• It is recommended to store and reuse the token on the server side for up to 1 hours to minimize authentication requests.
• Avoid generating a new token for each API call, as this increases latency.
• While there is no strict limit on authentication requests, fair usage policies apply.

API Endpoint

Method: POST

URL: https://<PA_RM_END_POINT>/retail-media/token

Request Header

Name	Value
Content-Type	application/x-www-form-urlencoded

Request Parameters (Body)

Parameter	Type	Required	Description
client_id	string	✅	This will be the application ID provided to your company by PA.
client_secret	string	✅	This will be the application secret provided to your company by PA.
grant_type	string	✅	Must always be client_credentials.

Response Payload

{
  "access_token": "xxxxxxxxxxxxxxxxxxxxxx",
  "expires_in": 90000,
  "token_type": "Bearer"
}

Response Parameters

Parameter	Type	Description
access_token	string	The token used as a bearer token for authenticating all subsequent API calls.
expires_in	integer	Duration in seconds during which the token remains valid.
token_type	string	Type of token.

Example Usage (JavaScript)

var myHeaders = new Headers();
myHeaders.append("Content-Type", "application/x-www-form-urlencoded");

var urlencoded = new URLSearchParams();
urlencoded.append("client_id", "YOUR_APPLICATION_ID");
urlencoded.append("client_secret", "YOUR_APPLICATION_SECRET");
urlencoded.append("grant_type", "client_credentials");

var requestOptions = {
  method: 'POST',
  headers: myHeaders,
  body: urlencoded,
  redirect:'follow'
};

fetch("https://<PA_RM_END_POINT>/retail-media/token", requestOptions)
  .then(response => response.json())
  .then(result=> { 
    console.log(result);
    const accessToken= result.access_token; // Use this token in subsequent requests
  })
  .catch(error => console.log('error', error));

Best Practices

• Store and reuse the token on the server side for 1 hours.
• Avoid requesting a new token before every API call, as it increases latency.
• Ensure proper security measures for storing client_id and client_secret.
• Implement error handling for token failures or expiration.
• Be aware of fair usage policies, even though there is no strict limit.
