## 7. Manage Keys {#7-manage-keys}

Create new API Signing and Payload Encryption Keys; you will need these to call the APIs in your Production project.
Note:   

* If you've enrolled in more than one program, the keys in your Production project can be used to call the APIs of all the selected programs. For example, if your Production project has Click to Pay, Guest Checkout Tokenization, and Secure Card on File - On Behalf Of Merchant Model, the project keys will be valid for calling the APIs of all selected programs.

* If you have more than one projects, you need to create distinct, separate keys for each project. The keys are **not** shared between projects.
