问题
I am using odata api, now I have an attribute on an entity that is an option select like :
attribute name is : status
values are: 1, 2, 3
names: done, progress, new
the thing is when I am using postman to fetch metadata and all I get for the fields 'status' its that its type integer.
Question how do I fetchj option names and values from metadata so I get values and names in response ?
Currently I get this:
<Property Name="status" Type="Edm.Int32">
<Annotation Term="Org.OData.Core.V1.Description" String="" />
</Property>
But I want to get the value and names on response ?

According to this article this is a multi-step process.
Please note that all the examples use HTTP GET.
First retrieve the entity's MetaData Id (for this example we're using the entity 'account'):
https://myOrg.crm.dynamics.com/api/data/v8.2/EntityDefinitions?$select=LogicalName,MetadataId&$filter=LogicalName eq 'account'
Returns:
{
"@odata.context": "https://myOrg.crm.dynamics.com/api/data/v8.2/$metadata#EntityDefinitions(LogicalName,MetadataId)",
"value": [{
"LogicalName": "account",
"MetadataId": "70816501-edb9-4740-a16c-6a5efbc05d84"
}]
}
Then retrieve the attribute's MetaDataId (in this example we're using the option set 'customertypecode'):
https://myOrg.crm.dynamics.com/api/data/v8.2/EntityDefinitions(70816501-edb9-4740-a16c-6a5efbc05d84)?$select=LogicalName&$expand=Attributes($select=LogicalName;$filter=LogicalName eq 'customertypecode')
Returns:
{
"@odata.context": "https://myOrg.crm.dynamics.com/api/data/v8.2/$metadata#EntityDefinitions(LogicalName,Attributes(LogicalName))/$entity",
"LogicalName": "account",
"MetadataId": "70816501-edb9-4740-a16c-6a5efbc05d84",
"Attributes@odata.context": "https://myOrg.crm.dynamics.com/api/data/v8.2/$metadata#EntityDefinitions(70816501-edb9-4740-a16c-6a5efbc05d84)/Attributes(LogicalName)",
"Attributes": [{
"@odata.type": "#Microsoft.Dynamics.CRM.PicklistAttributeMetadata",
"LogicalName": "customertypecode",
"MetadataId": "4e33af09-ba43-4365-a747-c7e4f9992172"
}]
}
Then query with the entity's and attribute's MetadataIds to get the option set values:
https://myOrg.crm.dynamics.com/api/data/v8.2/EntityDefinitions(70816501-edb9-4740-a16c-6a5efbc05d84)/Attributes(4e33af09-ba43-4365-a747-c7e4f9992172)/Microsoft.Dynamics.CRM.PicklistAttributeMetadata?$select=LogicalName&$expand=OptionSet
Returns (truncated at 2 values):

"@odata.context": "https://myOrg.crm.dynamics.com/api/data/v8.2/$metadata#EntityDefinitions(70816501-edb9-4740-a16c-6a5efbc05d84)/Attributes/Microsoft.Dynamics.CRM.PicklistAttributeMetadata(LogicalName,OptionSet)/$entity",

This could be vastly simplified, assuming all you want are the int values, and names for a particular option set attribute of an entity:
GET [Organization URI]/api/data/v8.2/EntityDefinitions(LogicalName='contact')/Attributes(LogicalName='status')/Microsoft.Dynamics.CRM.PicklistAttributeMetadata?$select=LogicalName&$expand=OptionSet($select=Options),GlobalOptionSet($select=Options)
The $select=LogicalName is just so it doesn't return all the other metadata for the attribute, and the $expand=OptionSet($select=Options) is for local option sets, and the GlobalOptionSet($select=Options) is for Global. If you know what type it is, you can skip it the other, but if you are putting this logic in a shared library (you are aren't you?) then adding both won't hurt:
