# Read-Only Report Builders

Some customers want their end users to have a report builder experience that is read-only, meaning that all reporting creating functionality is taken away. In some cases, even ephemeral analytical features like filtering and sorting are removed as well.

## How does it work?

When you generate a [JWT](/embedding-documentation/embed-secrets/intro) to be used for a report builder, you can add a `rbc` claim to the JWT that indicates the allowed editing features for the report builder.

This is an optional claim, meaning it is not needed to construct a valid JWT. If it's not passed in or the list that is passed in is the wildcard string (`["*"]`), all functionality will be allowed.

By **default**, end users will always be able to:

* View reports.
* Toggle favorite reports.
* Configure scheduled emails.

Pass specific key words to allow corresponding capabilities:

* `flt` -> Allow filtering of reports
* `srt` -> Allow sorting of reports
* `core` -> Allow core editing functionality (creating/editing reports, adding/editing views)
* `crt-view` -> Allow creating a new view within an existing built-in report
* `fork` -> Allow saving as a customer report after modifying an existing built-in report

> **Note**: If you are enabling `core` functionality, you don't need to explicitly include `view` or `fork`, as they are covered by `core`.

> **Note**: The `fork` and `crt-view` permissions will not allow modifying the underlying data.

> **Note**: The `fork` permissions will allow saving changes on forked customer reports.

By default if the `rbc` claim is in the JWT with the empty list (`[]`), then all editing capabilities are disabled. Here are some example configurations:

```json theme={null}
[]                 // Disable all editing capabilities
["flt", "srt"]     // Allow filtering and sorting
["flt"]            // Allow only filtering
["srt"]            // Allow only sorting
["crt-view"]           // Allow creating new views in built-in reports
["fork"]           // Allow saving modified built-in reports as new customer reports
["crt-view", "fork"]   // Allow both viewing and forking
```
