Set Variables Async (POST)

Update or create runtime process variables in the root scope of process instances.

Method

POST /process-instance/variables-async

Parameters

Request Body

A JSON object with the following properties:

Name Description

processInstanceIds A list of process instance ids that define a group of process instances to which the operation will set variables.

processInstanceQuery A process instance query like the request body for the Get Instances (POST) method to select process instances the operation will set variables to.

historicProcessInstanceQuery A historic process instance query like the request body for the Get Instances (POST) method to select process instances the operation will set variables to.

variables

A JSON object containing variable key-value pairs the operation will set in the root scope of the process instances. Each key is a variable name and each value a JSON variable value object.

Name	Description
value	The variable's value. For variables of type `Object`, the serialized value has to be submitted as a String value. For variables of type `File` the value has to be submitted as Base64 encoded string.
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.

Please note that if processInstanceIds, processInstanceQuery and historicProcessInstanceQuery are defined, the resulting operation will be performed on the union of these sets.

Response Body

A JSON object corresponding to the Batch interface in the engine. Its properties are as follows:

Name	Value	Description
id	String	The id of the batch.
type	String	The type of the batch. See the User Guide for more information about batch types.
totalJobs	Number	The total jobs of a batch is the number of batch execution jobs required to complete the batch.
jobsCreated	Number	The number of batch execution jobs already created by the seed job.
batchJobsPerSeed	Number	The number of batch execution jobs created per seed job invocation. The batch seed job is invoked until it has created all batch execution jobs required by the batch (see `totalJobs` property).
invocationsPerBatchJob	Number	Every batch execution job invokes the command executed by the batch `invocationsPerBatchJob` times. E.g., for a process instance migration batch this specifies the number of process instances which are migrated per batch execution job.
seedJobDefinitionId	String	The job definition id for the seed jobs of this batch.
monitorJobDefinitionId	String	The job definition id for the monitor jobs of this batch.
batchJobDefinitionId	String	The job definition id for the batch execution jobs of this batch.
suspended	Boolean	Indicates whether this batch is suspended or not.
tenantId	String	The tenant id of the batch.
createUserId	String	The id of the user that created the batch.

Response Codes

Code	Media type	Description
200	application/json	Request successful.
400	application/json	The variable value or type is invalid, for example if the value could not be parsed to an Integer value or the passed variable type is not supported If none of `processInstanceIds`, `processInstanceQuery` and `historicProcessInstanceQuery` is given If no or an empty array of `variables` is given If no process instance ids where found If a transient variable is set If the engine config flag `javaSerializationFormatEnabled` is `false` and a Java serialized variable is given See the Introduction for the error response format.
