What this connector is for

Uploads, reads, deletes and lists files in the platform's own managed file storage, scoped to your store. No connection is needed. Every file lives at a relative path (for example invoices/march.csv) under your store's namespace.

Every action, with its fields, is listed in the action reference.

File events

Uploading or deleting a file here can fire a File Event trigger if its File Pattern matches the relative path, since it is the same storage. The trigger data includes {{trigger.event}} (created_or_updated or deleted; storage can't tell a new file from an overwrite), {{trigger.key}} (relative path), {{trigger.size}} and {{trigger.eventTime}}.

Errors

Most storage-level errors resolve normally rather than failing the step. If the storage call fails in a recognizable way (for example reading a file that doesn't exist), Read File, Delete File and List Files typically return an HTTP-shaped error you can branch on: {{<stepReference>.response.status}} (for example 404) and {{<stepReference>.response.data.error}}. The one guaranteed exception is Upload File's size-limit check, which always fails the step.

Upload File

  • File names can't start with /, can't contain a .. segment, and are capped at 1024 characters. The body is plain text, or base64 for binary content.
  • On Conflict: overwrite (default) replaces the file at that exact path; createNew writes a new file with a timestamp before the extension (march.csv becomes march_1700000000000.csv) and leaves the original.
  • Retention of 7, 30, 90 or 365 days deletes the file automatically after that time; never (default) keeps it.
  • Size limit is enforced independently per store and per parent organisation, each defaulting to 25 MB unless configured. Exceeding either fails the step with an error naming the limit and the actual size.

Response: {{<stepReference>.response.data.fileName}} (the name actually written, which differs only with createNew), size (bytes) and ETag. For a step "Save Invoice": {{saveInvoice.response.data.fileName}}.

Delete File

{{<stepReference>.response.data.success}} is true on success. Deleting a path that doesn't exist still succeeds (the delete is idempotent), so it can't tell you whether the file existed; use List Files for that.

List Files

Filter by a prefix (folder-like, such as invoices/). Max Files is 1 to 1000 (default 1000).

  • {{<stepReference>.response.data.files}}: array of { fileName, lastModified, size, ETag }.
  • {{<stepReference>.response.data.isTruncated}}: true if more files exist.
  • {{<stepReference>.response.data.nextContinuationToken}}: present when truncated; pass it back as the Continuation Token for the next page.

Read File

The response shape depends on the format and whether the content needed batching:

Format and contentWhere it is
raw{{<stepReference>.response.data.content}} (base64)
xml.content, the full parsed object tree; never batched, Batch Size ignored
json, non-array top level.content, the parsed value
json array or csv, fits in Batch Size.rows (every row), .hasMore is false, no nextCursor
json array or csv, larger than Batch Size.rows (first batch), .hasMore is true, .nextCursor, .totalRows

Batch Size is 1 to 5000 (default 500). When a Cursor is set, the file name, format and CSV options are all ignored, since the cursor carries what's needed. CSV defaults to a header row (each row an object) and a , delimiter; without a header each row is a plain array.

For a step "Read Invoice Rows" reading a 2,000-row CSV with the default batch size, the first call returns 500 rows in {{readInvoiceRows.response.data.rows}}, {{readInvoiceRows.response.data.hasMore}} is true, and a Loop step re-runs Read File with Cursor set to {{readInvoiceRows.response.data.nextCursor}} until hasMore is false.

Step Name

What it's for

Every step in a workflow gets a name — either one you set or a default based on the connector and action (e.g. "Get Order Details", "Send Welcome Email"). It's shown throughout the UI and in your execution history, and it's also the source for the step's Reference — a camelCase identifier auto-generated from the name (e.g. "Get Order Details" → getOrderDetails) — which is what you actually use in {{...}} expressions to read this step's output from later steps. See Step Reference.

Rules

  • Must be at least 2 characters, and 50 characters or fewer.
  • Must be unique within the workflow — reusing a name that's already taken will be rejected, with a suggested alternative (e.g. "Get Order Details 2").
  • Can't be empty.

Tips

  • Prefer a descriptive, human-readable name over a generic one — "Get Order Details" is easier to work with later than "HTTP Request 2", especially once a workflow has a dozen steps.
  • Renaming a step updates every reference to it elsewhere in the workflow automatically.

Step Reference

Syntax

Any input field can reference earlier data using {{expression}}. The expression is evaluated as JSONata — so simple dot-paths and more advanced queries (filters, functions) both work.

Referencing a step's output

Use the step's Reference — a camelCase identifier auto-generated from its Name (e.g. "Get Order Details" → getOrderDetails), shown read-only wherever the step's fields are configured — followed by the field path. Elsewhere in these docs this general pattern is written as {{<stepReference>.field.path}}:

text
{{getOrderDetails.response.data.id}}
{{getOrderDetails.response.status}}

The raw display name won't work here even though it's what you see in the UI — {{Get Order Details.response.data.id}} isn't valid, since a bare name containing spaces isn't a single JSONata identifier. Always use the camelCase Reference.

You can also reference steps by position instead of by reference:

text
{{steps[0].response.data.id}}

Referencing trigger data

text
{{trigger.headers.authorization}}
{{trigger.body.customerId}}
{{trigger.query.page}}
{{trigger.params.orderId}}
{{trigger.method}}
{{trigger.path}}

Referencing workflow variables

text
{{variables.myVariable}}

See Variables for the full list of variable types and more examples, including connection-type variables.

Referencing runtime variables

A separate, mutable namespace written by the Variable connector while a run is in progress — not the same as the workflow-level variables above:

text
{{runtimeVariables.myVariable}}

Notes

  • If an expression can't be resolved (a typo in a step name, a field that doesn't exist), it resolves to an empty string rather than failing the workflow — check your execution history if a value comes through blank.
  • Object values are automatically JSON-stringified when interpolated into a string field.

Execution Settings

Fire-and-forget

When enabled, the workflow doesn't wait for this step to complete before moving to the next one. Use it for steps whose result nothing downstream depends on — logging, analytics, notifications — so they don't add latency to the steps that matter.

Continue on error

When enabled, a failure in this step doesn't stop the workflow — execution continues to the next step. The failure is still recorded in the execution history; this just controls whether it's fatal.

Combine the two for steps that are genuinely optional to the outcome: fire-and-forget so they don't add latency, continue-on-error so a failure in them (e.g. an analytics endpoint being briefly down) doesn't take down an otherwise-successful workflow run.

Caching

What it does

When enabled, a step's result is cached for a configurable TTL (time-to-live, in seconds). If the step runs again with the same effective cache key before the TTL expires, the cached result is returned instead of re-running the step.

Configuring it

  • Enabled — turn caching on or off for this step.
  • TTL — how long (in seconds) a cached result stays valid.
  • Cache key template — an expression (supporting the same {{...}} step reference syntax used elsewhere) that determines what counts as "the same call". By default this is based on the step's resolved input; a custom template lets you cache more narrowly or broadly than that.

When to use it

Good candidates are steps that call something slow or rate-limited but return the same answer for the same input within a short window — a lookup against a rarely-changing external system, for example. Skip it for steps whose result must always be fresh (anything involving live inventory, pricing, or payment state).

Locking

What it does

When enabled, only one execution of this step (for a given lock key) can run at a time. If a second execution tries to run the same step while a lock is held, it waits until the lock is released or the hold period elapses.

Configuring it

  • Enabled — turn locking on or off for this step.
  • Lock key — an expression (supporting the same {{...}} step reference syntax used elsewhere) that determines what counts as "the same resource". By default the lock is scoped to the step itself; a custom key lets you lock per-customer, per-order, or any other identifier that needs serialized access.
  • Period — how long (in seconds) the lock is held before it's automatically released, in case an execution doesn't complete normally.

When to use it

Use it whenever concurrent executions could race on the same resource — e.g. two workflow runs both trying to update the same order's status at once. A lock key scoped to the order id ensures only one of them proceeds at a time.
