Legacy Steps from Apps configuration view object

Steps from Apps is deprecated

We're retiring all Slack app functionality around Steps from Apps in September 2024. Learn more.

Configuration modals are used in Workflow Builder during the addition of Steps from Apps

To define these modals, apps create view objects — packages of information that describe layout, interactivity, and other useful metadata.

Configuration view objects are used within the following Web API methods:

Configuration modals are used just like regular modals, with a few differences.

Below is a reference of all the possible fields within a configuration view object:

Fields

Field	Type	Required?	Description
`type`	String	Yes	The type of view. Always set to `workflow_step`
`blocks`	Array	Yes	An array of blocks that defines the content of the view. Max of 100 blocks.
`private_metadata`	String	No	An optional string that will be sent to your app in `view_submission` and `block_actions` events. Max length of 3000 characters.
`callback_id`	String	No	An identifier to recognize interactions and submissions of this particular view. Don't use this to store sensitive information (use `private_metadata` instead). Max length of 255 characters.
`submit_disabled`	Boolean	No	When set to `true`, disables the `submit` button until the user has completed one or more inputs.
`external_id` or `view_id`	string	Yes	A unique identifier of the view set by the developer. Must be unique for all views on a team. Max length of 255 characters. Note: only one of either `view_id` or `external_id` is required.

If you use non-standard characters (including characters with diacritics), please be aware that these are converted and sent in unicode format when you receive the view callback payloads.
