+# external item add
+
+Creates external item
+
+## Usage
+
+```sh
+m365 external item add [options]
+```
+
+## Options
+
+```md definition-list
+`-i, --id <id>`
+: The ID of the item to create
+
+`--externalConnectionId <name>`
+: The ID of the external connection on which to create the item
+
+`--content <content>`
+: External item content
+
+`--contentType [contentType]`
+: Type of content to load. Allowed values: `text` (default), `html`
+
+`--acls <acls>`
+: List of permissions to set on the item, in the format `accessType1,type1,value1;accessType2,type2,value2`, eg. `grant,everyone,everyone`
+```
+<Global />
+
+## Remarks
+
+When creating an external item, the options you specify will map to the external item properties, eg. `--author "Steve"` will set the `author` property of the external item to `Steve`.
+
+If in your schema you have a multi-value property, to specify its value you need two things:
+
+- you need to separate multiple values using `;#`, eg. `--author "Steve;#Bill"`
+- you need to specify the type of the property as defined in the schema, eg. `[email protected] "Collection(String)"`
+
+When creating items you can specify one or more permissions that define who can access the external item. The format of the permissions is `accessType1,type1,value1;accessType2,type2,value2`, eg. `grant,everyone,everyone`.
+
+You can use the following access types:
+
+- `grant` - grants access to the specified users or groups
+- `deny` - denies access to the specified users or groups
+
+You can use the following types:
+
+- `everyone` - everyone
+- `group` - an Entra group
+- `user` - an Entra user
+- `everyoneExceptGuests` - everyone except external users
+- `externalGroup` - a group defined in the external system from which you're importing the content
+
+For more information about using these options, see the Microsoft Graph API documentation and documentation about Microsoft Graph connectors.
+
+## Examples
+
+Creates an external item with simple properties that everyone is allowed to access
+
+```sh
+m365 external item add --id "pnp-ensure-siteassets-library" --connectionId "samplesolutiongallery" --content "Ensure that the Site Assets library is created." --title "Ensure the Site Assets Library is created" --description "Ensure that the Site Assets library is created." --authors "Phil Harding" --acls "grant,everyone,everyone"
+```
+
+Creates an external item with multi-value properties accessible only to users from the specified Entra group
+
+```sh
+m365 external item add --id "pnp-ensure-siteassets-library" --connectionId "samplesolutiongallery" --content "Ensure that the Site Assets library is created." --title "Ensure the Site Assets Library is created" --description "Ensure that the Site Assets library is created." [email protected] "Collection(String)" --authors "Phil Harding;#Steve Smith" --acls "grant,group,Super users"
