POST /condition

Parameters

Request Body

A JSON object with the following properties:

|value|The variable's value. For variables of type Object, the serialized value has to be submitted as a String value.

|type|The value type of the variable.|valueInfo| A JSON object containing additional, value-type-dependent properties.
For serialized variables of type Object, the following properties can be provided:

• objectTypeName: A string representation of the object's type name.

• serializationDataFormat: The serialization format used to store the variable.
  For serialized variables of type File, the following properties can be provided:

• filename: The name of the file. This is not the variable name but the name that will be used when downloading the file again.

• mimetype: The MIME type of the file that is being uploaded.

• encoding: The encoding of the file that is being uploaded.
  The following property can be provided for all value types:

  |businessKey|Used for the process instances that have been triggered after the evaluation.
  |tenantId|Used to evaluate a condition for a tenant with the given id. Will only evaluate conditions of process definitions which belong to the tenant.
  |withoutTenantId|A Boolean value that indicates whether the conditions should only be evaluated of process definitions which belong to no tenant or not. Value may only be true, as false is the default behavior.
  |processDefinitionId|Used to evaluate conditions of the process definition with the given id.

Result
