List S3 files node for Joomla and WordPress

Overview

Lists objects in an S3 bucket (ListObjectsV2), paginating automatically until the max total is reached.

When the flow reaches this step, JOrchestrator executes List S3 files against your linked site or an external integration, using the field values you set on General and Design. Downstream steps can read the output payload fields defined for this node.

Why use this node

List S3 files is a action step in the Cloud › AWS group. Action steps run in the middle or end of a flow. They perform work on your CMS, call external services, or transform data for the next step.

Typical reasons teams add List S3 files to a flow:

Automate "List S3 files" as part of a larger Joomla or WordPress workflow
Replace manual aws work with a repeatable, logged flow step
Chain with triggers, logic, and messaging nodes on the same canvas

Example workflows

Common patterns on the canvas:

Trigger or Webhook → upstream steps → List S3 files → Send Email or CMS update
Scheduled trigger → List S3 files → Debug (while testing) → production action

How to set it up

Bucket name and optional prefix; set Per page (API batch) and Max total files; credentials from Node Configuration → AWS.

Good to know

Output includes a files JSON array (bucket, objectKey, filename, size). Wire Process List to files to handle each object downstream — e.g. 1000 total with 100 per page runs 10 API calls in one node.

Properties panel

The designer shows these tabs for this node:

Tab	Purpose
Info	Plain-language description and output payload fields for downstream steps
General	Canvas label and read-only node ID
AI	Optional assistant to help draft settings from plain language
Design	Node-specific configuration fields

System (automatic — not edited by the user)

These fields are managed by the designer or runtime — you do not type into them directly:

Property key	Label	Type	Required	Visible when	Notes
`_nodeId`	Node ID	`node-id`	No	—	—
`_payloadFields`	Available Fields	`payload-panel`	No	—	—

User-configured — General tab

Property key	Label	Type	Required	Visible when	Notes
`label`	Label	`text`	No	—	Node label

User-configured — Design tab

Property key	Label	Type	Required	Visible when	Notes
`bucket`	S3 bucket	`payload-text`	Yes	—	my-bucket
`prefix`	Key prefix	`payload-text`	No	—	uploads/2025/ Optional folder-style prefix to limit results.
`maxKeys`	Per page (API batch)	`select` (`100` \| `500` \| `1000`; default: `100`)	No	—	Objects requested per cloud API call while paginating.
`maxTotalFiles`	Max total files	`select` (`100` \| `500` \| `1000` \| `2500` \| `5000` \| `10000`; default: `1000`)	No	—	Total files to collect across pages. Node loops automatically (e.g. 1000 total with 100 per page = 10 API calls).
`delimiter`	Delimiter	`select` (` `\|` /`; default:` `)	No	—	Use / to group keys into folder prefixes in prefixes[].
`_listResumeAdvanced`	Resume listing (advanced)	`toggle` (default: `false`)	No	—	Only needed when listing more objects than Max total files — e.g. chain a second List node using nextContinuationToken from the first.
`continuationToken`	Start continuation token	`payload-text`	No	`listShowContinuationToken`	{{List S3.nextContinuationToken}} Resume from a prior nextContinuationToken when isTruncated was true.

CMS site configuration (not on this node's properties panel)

Credentials, API keys, mailers, SMTP, and integration defaults are configured in the CMS plugin under Node Configuration, not per step on this node. Link the flow to a domain before testing CMS-backed fields.

Output payload fields

After this step runs, later nodes can reference these fields using placeholders such as {{list_s3_files.success}}.

Field key	Type	Description
`success`	boolean	Whether the operation completed successfully.
`bucket`	string	Cloud storage bucket name.
`prefix`	string	Text value from this node's output.
`delimiter`	string	Text value from this node's output.
`pageSize`	number	Objects requested per API call (Per page setting).
`maxTotalFiles`	number	Cap on total objects collected across all pages.
`pageCount`	number	Number of API list calls made to build files[].
`count`	number	Number of items in the result set.
`files`	array	JSON array of listed objects — use Process List with listPath files.
`keys`	array	Flat array of object keys from files.
`items`	array	Same as files (alias for iterator compatibility).
`prefixes`	array	Array of values from this node's output.
`isTruncated`	boolean	True when more objects exist beyond maxTotalFiles.
`nextContinuationToken`	string	Token to resume listing if isTruncated is true.
`message`	string	Human-readable status, error, or result summary.
`files.0.bucket`	string	Nested field "files.0.bucket" from this node's output payload.
`files.0.objectKey`	string	Nested field "files.0.objectKey" from this node's output payload.
`files.0.filename`	string	Nested field "files.0.filename" from this node's output payload.
`files.0.size`	number	Nested field "files.0.size" from this node's output payload.
`files.0.lastModified`	string	Nested field "files.0.lastModified" from this node's output payload.
`files.0.etag`	string	Nested field "files.0.etag" from this node's output payload.
`files.0.storageClass`	string	Nested field "files.0.storageClass" from this node's output payload.

Validation rules

S3 bucket (bucket) must be filled before the flow can be saved.
