This request contains 2 major parameters listed below and detailed further down the section:

1. pipelineTasks
2. inputData

### Parameter: `pipelineTasks`

**Type:** Array\
\
This parameter takes an array of tasks, in the form of dictionary of **`taskType`** and **`config`**, that are to be done by the integrator. \
