Custom task input_data

Configure the custom job_type with exact prompt, inputFields, outputField, and supported product input_data field names.

Purpose

A Custom task gives selected product fields to a prompt and writes the generated result to one selected field. Set job_type to custom.

Valid JSON example

{
  "prompt": "Write a concise search description from the title, description, and tags.",
  "inputFields": ["title", "description", "tags"],
  "outputField": "seoDescription"
}

JSON fields

Field	Type	Required	Values and meaning
`prompt`	string	Yes	Non-empty instructions for the transformation. Refer to the selected inputs by their meaning, not by guessing unavailable data.
`inputFields`	string array	Yes	One or more supported fields to provide as prompt context.
`outputField`	string	Yes	One supported field where CopyHero writes the generated result.

Supported inputFields values are:

title
description
vendor
productType
tags
variants
images
seoTitle
seoDescription
extra

Supported outputField values are title, description, vendor, productType, tags, seoTitle, seoDescription, and extra.

extra is workflow-internal working state. It can pass information to later Custom or Agent steps, but it is not a Shopify product field and is not synced to Shopify.

Validation and run-time behavior

The editor requires a non-empty prompt, at least one input field, and one output field.
Use description, not descriptionHtml, in this public input_data format.
The task reads only the selected inputs. Selecting fewer relevant fields keeps the prompt context focused.
Writing replaces the chosen output value for the following workflow steps. Do not overwrite a value that a later step still needs in its original form.
A Custom task produces model-generated output. Review important content before publishing it.
