Lists one page of a bucket's objects under a prefix. Feed next page token back into page token to walk a large bucket.

In pins 7 + flow

flow
flow
connection required
s3connection
The object storage connection to use, from an open connection block.
bucket
value
Bucket name. Leave empty to use the bucket set on the connection.
prefix
value
Only list keys starting with this, for example mu/ab/.
delimiter
value
Optional. Set to / to get a folder-style listing: shared path segments come back on prefixes instead of objects.
max keys
number
Objects per page, 1–1000. Defaults to 1000.
page token
value
The next page token from a previous run, to continue the listing.
start after
value
Begin the listing after this key. Ignored when a page token is given.

connection
s3connection
The same connection, so it can be passed to the next block.
success
condition
error
value
objects
array
Array of {key, size, etag, last_modified, storage_class}.
prefixes
array
Common prefixes, when a delimiter was given. These are the "folders".
count
number
Number of objects on this page.
has more
condition
True when more pages follow.
next page token
value
Pass back in as page token for the next page.

Returns ONE PAGE of keys under `prefix`. Pagination is explicit and deliberate: a media bucket holds millions of keys, so this never loops internally. When `is_truncated` is true, pass `next_page_token` back in as `page_token` to get the next page : the loop and its termination stay visible on the canvas. `max_keys` is capped at 1000 (the server's own ceiling) and defaults to it. `delimiter` groups keys: with "/" the shared path segments come back on `prefixes` instead of `objects`, turning a flat keyspace into a directory listing. `start_after` applies only to a first page and is IGNORED when `page_token` is set. `objects` is an array of {key, size, etag, last_modified, storage_class}. Keys are url-decoded, so a key with a space or a non-ASCII character comes back readable. success=false with NO_CONNECTION, MISSING_BUCKET, or an S3 code such as NoSuchBucket or AccessDenied.
