Simulator in sandbox environment

Last updated: 02-Mar-2023


This guide provides instructions for integration setup utilizing Simulator in a Sandbox Environment. To proceed, follow the steps below.

Step 1: Obtaining API Keys

The recent update of Entity Service and Verifone Central makes it possible to generate the API Keys directly in the Admin Panel. To obtain the keys, perform the following:

  1. Ensure the valid user logs into the necessary site.
  2. Navigate to the user settings at the top right corner, and select the "API Keys" option from the dropdown menu.

  3. On the API Keys page, click the "Create API Key" button.

  4. To copy the key, click the "Copy public key" button and paste it to a safe location. Once the key has been copied, the success message will appear at the right bottom corner of your screen. Note: Your API key expiration period is one year.

  6. Locate your "user-uid" by highlighting and copying the rest of the URL in your browser's address field. See the screenshot below.

Note! The expiration date of API Keys is one year from the date of activation. The system automatically sends email notifications every week during the last three months and every day during the last week before the expiration date. 

Step 2: Encoding API Key

To encode API keys, follow the authentication method below.

  1. Indicate Authorization: Basic "user-uid:api key" in the header.
  2. Replace the "user-uid" and "api key" values with the necessary ones.
  3. Encode the whole string in base64.

For example:
The following "user-uid:api key" string 777c31b3-a85f-4823-93a5-9055d1b:cGEFFLjYuUCtmerXlhTfAdaPpYVnXDJZmg

results in a base64 Nzc3YzMxYjMtYTg1Zi00ODIzLTkzYTUtOTA1NWQxYjpjR0VGRkxqWXVVQ3RtZXJYbGhUZkFkYVBwWVZuWERKWm1n

Thus, the header should look like this:

Authorization: Basic Nzc3YzMxYjMtYTg1Zi00ODIzLTkzYTUtOTA1NWQxYjpjR0VGRkxqWXVVQ3RtZXJYbGhUZkFkYVBwWVZuWERKWm1n

    Step 3: Importing the Integrator Collection into Postman

    1. Download the Integrator Collection .zip archive.
    2. Unzip the archive.
    3. Locate the Integrator Collection.postman_collection.json file.
    4. Import the collection by using the File > Import menu option in Postman. See the screenshot below.

    1. Navigate to the GET Health check menu item on the Collections page.
    2. Click the Authorization menu item below the request URL field.
    3. Choose the Basic Auth option from the Type dropdown list.
    4. Paste your "user-uid" into the username field and "api key" into the password to send the request. See the screenshot below.
