Partner Solution Key Enablement {#isv-partner-starter-solution-key-intro}
=========================================================================

You can process transactions on behalf of merchants who are using your registered solution. To enable merchants to use your solution, you must create a *partner solution key* . The acquirer you are partnering with must then update the merchant's account to use the key. `Cybersource` also authenticates the merchants, ensuring that the registered solution only performs actions authorized by the merchants.  
This section explains how you can set up a partner solution key to enable your solutions to process transactions on behalf of merchants.
