Sforce Call Options Header

Use the Sforce-Call-Options header to specify client-specific options when accessing Bulk API 2.0 resources.

Field name: Sforce-Call-Options

Field values:

  • client—A string that identifies a client, for use, for example, in event log files.
  • defaultNamespace—A string that identifies a developer namespace prefix. Resolve field names in managed packages without having to specify the namespace everywhere.

Example:

If the developer namespace prefix is battle, and you have a custom field called botId in a package, set the default namespace with the call options header:

Then queries such as the following succeed:

In this case, the actual field queried is the battle__botId__c field.

Using this header allows you to write client code without having to specify the namespace prefix. In the previous example, without the header you must write battle__botId__c.

If this field is set, and the query also specifies the namespace, the response doesn’t include the prefix. For example, if you set this header to battle, and issue a query like SELECT+Id+battle__botID__c+FROM+Account, the response uses a botId__c element, not a battle_botId__c element.

The defaultNamespace field is ignored when retrieving describe information, which avoids ambiguity between namespace prefixes and customer fields of the same name.
