Get a ProductID Automatically

API Resources

If you are an integrator you will want to get started posting data to our API and sending faxes programmatically.

You will need to get the ProductId which is the unique identifier for your fax line. Each fax line has a different unique GUID (or Hashed ID) which allows you to send / receive and manage your faxes individually.

The natural question we get is:

I signed up and I need my API Key. You can ask us by submitting a help desk ticket or you can use our API to get your API Key.


  1. You signed up for a WestFax account.
  2. You have a basic understanding of how to make API calls.
  3. (Optional) Import our Postman Documentation.

There is an API call named: Profile_GetF2EProductList

​When you call this request with your Username and Password you will get output like this:

(Note: This is not real. We masked the ID field) ​

Here is the CURL request: ​
curl --location --request POST '' \
 --form 'Username="{{User}}"' \
 --form 'Password="{{Pass}}"' \
 --form 'Cookies="false"'

​Passing in your values for {{User}} and {{Pass}} ​

Results in: ​

 "Success": true,
 "Result": [
   "Id": "00000000-1111-2222-3333-4444444444",
