Installing Synapse API Clients

API clients provide a way to use Synapse programmatically. This page shows you how to install a client and login to Synapse programmatically. Packages to interface and access data within Synapse are available for:

  • Command line

  • Python

The Synapse command line client is implemented in Python and comes with the Synapse Python package. To install the Synapse command line client, make sure that you have Python and pip installed. For more information, see the Python and pip installation instructions.

After installing Python and pip, open your terminal (Mac OS or GNU/Linux) or Command Prompt (Windows), and run the following command:

pip install synapseclient

synapse login "username" "password"
synapse -h

For more documentation on the command line client, see the synapseclient docs.
