# Salesforce CMS parameters

> After you install the Salesforce CMS integration, new parameter types are available.

Source: https://docs.uniform.app/docs/integrations/content/salesforce-cms/salesforce-cms-parameters

After you install the Salesforce CMS integration, the following
parameter types are available. You can use these to incorporate
content from Salesforce CMS into your components and compositions.

| Parameter type | Description |
| --- | --- |
| [Salesforce CMS Entry Selector](#salesforce-cms-entry-selector) | Select a content entry from Salesforce CMS. |

## Salesforce CMS Entry Selector

This parameter type allows a Uniform user to select a Salesforce CMS content entry.

### Add parameter to component

To allow a user to select an entry from Salesforce CMS,
you must add a parameter to a component. The parameter is used
to store the identifier to the selected entry when the user
selects it.

1. In Uniform, navigate to your component.
2. Add a new parameter using the parameter type **Salesforce CMS Entry Selector**.
3. The following values can be specified:

   | Name | Description |
   | --- | --- |
   | Allowed Content Types | Specifies which content types will be available to select from when the parameter value is edited. You can select multiple content types to allow the user to select from a larger set of entries. |
   | Required | Indicates whether the value is required when the component is used. |

### Edit parameter value

When you use a component with a Salesforce CMS Entry Selector parameter,
by default no entry will be selected. You are prompted to
select an entry.

1. Click **Select**.

2. Click the entry you want to select.

   > A couple of filters are available. The dropdown allows you to filter by content model. The text box allows you to filter by entry content.
3. Click **Accept** to save your selection.
4. You will see details about the document you selected, including the title and some metadata.

### Configure an enhancer

When an entry is selected, Uniform only stores the identifier
for the entry. Your front-end application must retrieve the
details for the entry. Uniform provides an enhancer to
simplify this process.

> **Tip:**
>
> Using the enhancer provided by Uniform saves you from having
> to write logic to interact directly with Salesforce CMS.

#### How Uniform stores the selected document

The following is an example of what Uniform stores
for the parameter. It stores the identifiers for
the selected entries.

```json
{
  "type": "sfcmsEntrySelector",
  "value": "##################"
}
```

#### Add the enhancer

Uniform provides an enhancer so you don't need to write the API
calls to Salesforce CMS to retrieve data for entries.

1. In Salesforce CMS, get the following values:

   - Channel ID
   - Instance URL
   - Organization ID
2. Add the following npm packages to your front-end application:

```
@uniformdev/canvas-salesforcecms
```

1. In a text editor, open the file where you retrieve the
   composition definition from Uniform.

   > **About this step:**
   >
   > You are looking for the code calls the async function
   > `getComposition`. The code below assumes the
   > object returned is set in a variable `composition`.
2. Add the following import statements:

   ```javascript
   import { EnhancerBuilder, enhance } from '@uniformdev/canvas';
   import { 
       CANVAS_SFCMS_PARAMETER_TYPES, 
       createSalesforceCMSClient, 
       createSalesforceCMSEnhancer 
   } from '@uniformdev/canvas-salesforcecms';
   ```
3. Add the following code:

   ```javascript
   const cmsClient = createSalesforceCMSClient({
       channelId: '!!! YOUR SALESFORCE CMS CHANNEL ID !!!',
       instanceUrl: '!!! YOUR SALESFORCE CMS INSTANCE URL !!!',
       organizationId: '!!! YOUR SALESFORCE CMS ORG ID !!!',
   });
   ```

   > **About this step:**
   >
   > We recommend you moving the Salesforce CMS credentials to
   > environment variables rather than hard-coding them in the
   > front-end app.
4. Add the following code:

   ```javascript
   const enhancer = createSalesforceCMSEnhancer({
       client: cmsClient,
   });
   ```
5. Add the following code:

   ```javascript
   await enhance({
       composition,
       enhancers: new EnhancerBuilder().parameterType(
       CANVAS_SFCMS_PARAMETER_TYPES,
       enhancer,
       ),
       context: {},
   });
   ```

   > **About this step:**
   >
   > This registers the enhancer to be used for any occurrence
   > of the Salesforce CMS Entry Selector parameter.

> **Next steps:**
>
> Now, the parameter value in the composition is mutated to
> include the field values for the selected Salesforce CMS entry
> (instead of just being an identifier).
