Create a namespace for your organization by registering a namespace prefix.
If you’re not creating managed packages for distribution then registering a namespace prefix
isn’t required, but it’s a best practice for all but the smallest organizations.
Your namespace prefix must:
- Begin with a letter
- Contain one to 15 alphanumeric characters
- Not contain two consecutive underscores
For example, myNp123 and my_np are valid
namespaces, but 123Company and my__np aren’t.
To register a namespace prefix:
- From Setup, enter Packages in the Quick Find box.
Under Create, select Packages.
- In the Developer Settings panel, click Edit.
- Review the selections that are required for configuring developer
settings, and then click Continue.
- Enter the namespace prefix you want to register.
- Click Check Availability to determine if the
namespace prefix is already in use.
- If the namespace prefix that you entered isn’t available, repeat the
previous two steps.
- Click Review My Selections.
- Click Save.
