The assignTasks() GraphQL mutation is used to assign node tasks. To unassign tasks, use the unassignTasks() mutation.

Syntax

graphql
assignTasks(
      nodeID: integer!,
      tasks: [NodeTaskEnum]!
   ): [NodeTaskEnum]!

For the input, you have to provide the unique number of the node, and a comma-separated list of tasks. The special input datatype used is the same as returned datatype. See the Returned Datatype section for a list of choices.

Given Datatype

For the input, you would provide the unique number of the node. You'll also have to give a comma-separated list of tasks. For that there's a special enumerated datatype (see the Returned Datatype section).

Table: Input Using Standard Datatypes

Parameter Type Required Default Description
nodeID integer yes   The unique identifier of the node.

Returned Datatypes

Both the given and returned special datatypes are the same enumerated list with only couple of choices. They're listed and described here:

Table: NodeTaskEnum

ParameterTypeRequiredDefaultStabilityDescription
Some arguments may be required, as indicated in the Required column. For return datatypes, this indicates that you must specify which fields you want returned in the results.
