"description": "An Access Token Request must be done in order to execute any request to the GP-API. As you can see in the body of the request there are 3 variables:\r\n- app_id: This is your individual app id that was given to you when your app was created in the dev portal. It indicates to the GP-API what accounts and permissions you have access to e.g. Settlements, Disputes etc.\r\n- nonce: this is a random unique string used to calculate the secret. In this case we use the current date and time in string format for nonce. Every time access token is run, value is unique due to time change.\r\n- secret: as the app_key is never sent over the Internet, we use encryption to hide the app_key, SHA512(nonce + app_key). This function can be seen in Pre-request Script for this request. GP-API decrypts SHA512 and if app_key matches one on GP-API record, then access token is given.\r\n- seconds_to_expire: this is how long you want your access token to be valid in seconds. We do not recommend having an access token live for more than 24hrs.\r\n\r\n\r\nIn the response received back, you will see the merchant_id along with the accounts and permissions available for the current merchant e.g Settlement Reporting or Tokenization etc.. The merchant_id is associated with your app and it determines what accounts of the API your app has access to and by extension, the resources and permissions.\r\n\r\nFor more info on retrieving an access token, visit: https://developer.globalpay.com/api/access-token#/Create%20Access%20Token/post_accesstoken"
