You can have the WebJobs write the values to a database or to Azure Storage (e.g. a queue), and have the Web App read them from there.

Atlassian Bamboo command tasks not running correctly | 36,808,047 | 0 | 0 | 837 | 0 | python-3.x,selenium,centos6,bamboo | I solved the problem by changing the task type from a command task to a script task.
