* Create a custom extenion for Groups using Graph API: Currently, spfx has no permissions to create custom extensions
for entities in Graph API. To create the custom extension, you can use the [MS Graph Explorer website](https://developer.microsoft.com/en-us/graph/graph-explorer).
To create the extension you must do a POST request to:
```js
POST https://graph.microsoft.com/v1.0/schemaExtensions
content-type: application/json
{
"id": "inheritscloud_SalesCustomData",
"description": "Adding custom data to Groups created for sales",
"owner": "ac638f16-63c2-462b-95a4-16f8a60b0628",
"targetTypes": [
"Group"
],
"properties": [
{
"name": "businessUnit", "type": "String"
},
{
"name": "estimatedBudget", "type": "Integer"
},
{
"name": "expectedClosedDate", "type": "DateTime"
}
]
}
```
See here for more information about the attributes: [https://developer.microsoft.com/en-us/graph/docs/api-reference/beta/resources/schemaextension](https://developer.microsoft.com/en-us/graph/docs/api-reference/beta/resources/schemaextension)
__Note__:
* For the _id_ attribute, You can assign a value in one of two ways:
* Concatenate the name of one of your verified domains with a name for the schema extension to form a unique string in this format, {domainName}_{schemaName}. As an example, contoso_mySchema.
* Provide a schema name, and let Microsoft Graph use that schema name to complete the id assignment in this format: ext{8-random-alphanumeric-chars}_{schema-name}. An example would be extkvbmkofy_mySchema.
* The _owner_ attribute must be a valid ClientId registered in Azure AD
* The _targetTypes_ is an array with the different Entities that you want to extend (users, groups, event, message). However, spfx only allows to update Groups, so the value is set to _group_
## Minimal Path to Awesome
* clone repo
* edit _GraphSchemaExtenion.tsx_ file and change line 141 with the _id_ "inheritscloud_SalesCustomData" assigned when you created the custom Schema extension
* run _gulp serve_
