Why do you need it?

This snippet might be helpful to you if you need to separately store a list of all your SignalWire numbers within a project. You can use one or more of the following parameters to further filter your records and return only the specific information that you need: FriendlyName, Origin, PhoneNumber.

You can read more about the List Numbers API here.

What does it do?

This code will query your project and return all of the numbers in your project, limited by whatever parameters you choose to use. It will then take this data and insert it into a CSV for your records or further use.

System/Technical specifications
  1. For the python version of this snippet, You MUST have pandas installed and imported for this to work. Pandas is required to create the dataframe and export to CSV.

  2. You must have the SignalWire Python SDK installed. You can install that here.

Change the following variables
  1. ProjectID - Your project ID is an alphanumeric string that tells the SignalWire SDK where to find your project. You can find this in an easily copyable format by going to your SignalWire Portal and clicking the API tab on the left-hand side.

  2. AuthToken - Your Auth Token is an alphanumeric string that helps to authenticate your HTTP requests to SignalWire. You can create this (if you haven’t already) or copy this in an easily copyable format by going to your SignalWire Portal and clicking the API tab. If you have not created an API token, press the blue new button. If you have, click show and copy the string.

  3. SpaceURL - Your space URL is the domain of your space, i.e. This can also be found in an easily copyable format within the API tab in your SignalWire space.

  4. If you want to add a parameter to sort by, you can add it within client.incoming_phone_numbers_list().

The snippet

This snippet uses the Python SDK to query the SignalWire API and return all the numbers matching the parameters you choose to set. This data is then inserted into a Pandas DataFrame and exported to a CSV file with the following columns:

  • Phone Number

  • SID
