Postman Setup

Run in PostmanRun in Postman

You can use Postman to make calls to Galileo's Program API. This guide describes how to set up Postman, add the Galileo Pro collection, and test a simple call to the API.

Download and install Postman

First, download and install the Postman application. To do this:

  1. Go to
  2. Click Download the App.
  3. When the installation file has finished downloading, click the file to install the application.
  1. Follow installation prompts on the screen.

Add the Galileo Pro collection

When installation is complete, follow these steps to add the Galileo Pro collection to Postman.

  1. Click Run in Postman below to run the collection.

    Run in PostmanRun in Postman

  2. In the Web page that opens, select your operating system.

  1. Click Open Postman if prompted.
  2. In Postman, the Galileo Pro collection is displayed in the Collections tab.

Edit collection variables

Next, copy your credentials from the Sandbox Dashboard into the Galileo Pro collection variables in Postman. These are identifying variables that will apply across the collection.



You can also use Postman with the Client Validation and Production environments. Credentials for these environments are not in your Sandbox Dashboard, rather, you will need to get them from your Galileo representative.

To add your credentials to Postman:

  1. In Postman, select Galileo Pro to open the collection tab.
  1. In the collection tab, click Variables. This tab will store your credentials that apply across the collection.



There are two pre-populated collection variables:

  • url contains the base URL for sending API calls to the Sandbox environment. If you use Postman with CV or Production environments, replace this with your URL from Galileo.
  • responseContentType sets the response format for API calls. The default format is json, but you can change it to xml if you prefer.
  1. To access your credentials, log in to the Sandbox Dashboard:
  1. Scroll down to API CONNECTION DETAILS. These are your credentials for the Sandbox environment.
  1. In Postman, paste your credentials into both INITIAL VALUE and CURRENT VALUE columns for:
    • apiLogin β€” API LOGIN in the Sandbox Dashboard
    • apiTransKey β€” API TRANS KEY in the Sandbox Dashboard
    • providerId β€” TEST PROVIDER ID in the Sandbox Dashboard
    • prodId β€” TEST PRODUCT ID in the Sandbox Dashboard
    • programId β€” TEST PROGRAM ID in the Sandbox Dashboard



If you are using Postman with the CV or Production environment, enter the credentials from your Galileo representative instead of your Sandbox credentials.

  1. Click Save.

Download client certificate

Next, download your client certificate from the Sandbox Dashboard and apply it in Postman. To download your certificate from the Sandbox Dashboard:

  1. On the Sandbox Dashboard page, find the client certificate near the bottom of the page and click Download.
  1. In Postman, click the settings icon in the upper-right corner and select Settings.
  1. In the SETTINGS window, click Certificates.
  2. Toggle CA Certificates to ON.
  3. Click Select File and upload the .pem file containing your certificate.

Test ping call

You can run a simple test to verify that your Galileo Pro collection is ready to run in Postman. Follow these steps to send a test ping.

  1. In Postman, type β€œping” in the filter box.
  2. Select the Ping endpoint.
  1. In the Body tab, you can hover over text in curly braces to see the values.
    • Most of these call in the values from your collection variables.
    • For transactionId, the value {{$guid}} is a Postman command that will generate a random ID for each API call that you send.
  1. Click Send and check the response. The response status should display Success.
