# Bubble Plugin API Calls: Exploring Diverse Parameter Types

If you are developing a plugin using an API, you may have noticed that there are three types of parameters - private, hidden, and secret, which differ from the private and public parameters found in an API connector.

What's the difference between them?

|  | Public | Hidden | Secret |
| --- | --- | --- | --- |
| End user can change the value? | yes | no | no |
| Who can see the value | everyone | can see via the inspect element | no |

**If you set the parameter type to public**\-

Anyone with access to the page can view and modify the value, making the parameter value public.

**If you set the parameter type to hidden**\-

The plugin installer cannot change the value, but everyone can view its value using the inspect element feature.

**If you set the parameter type to secret-**

No one can see the value, and they cannot change it either.
