Amazon S3 trigger - New CSV file

Triggers when a CSV file is added in a selected bucket/folder in Amazon S3.

Checks selected folder for new or updated CSV file once every poll interval. The output includes the file’s metadata and file contents, which are CSV rows delivered in batches.

Note that in Amazon S3, when a file is renamed, it is considered a new file. When a file is uploaded and overwrites an existing file with the same name, it is considered an updated file but not a new file.

Input fields

Region	The region of the bucket to monitor for new/updated file, for example, us-west-2. In Amazon S3, go to Bucket > Properties > Static website hosting to find your region in the Endpoint URL.
Bucket	The bucket to monitor for new CSV file. Select a bucket from the picklist or enter the bucket name directly.
Column separator	Delimiter separating the columns in the CSV file.
Folder path	The folder to monitor for new CSV files. Define full path (for example, folder 1/subfolder 1). Sub-folders will not be monitored. Root folder or restricted folder is used by default.
Include files not ending with .csv?	Handle the cases when your CSV files exported from other systems may not have .csv extension. Ensure that all files in this folder are CSV parsable.
Column names	The column names of the CSV file. You can manually define the column names with each column header per line.
Batch size	Workato divides the CSV file into smaller batches to process more efficiently. This field defines the number of CSV rows to process in each batch (Maximum of 1000 rows/batch). Use a larger batch size to increase data throughput. Sometimes, Workato will automatically reduce batch size to avoid exceeding API limit. Learn more about Batch Processing.
Skip header row?	Select Yes if CSV file contains header row. Workato will not process that row as data.

This trigger supports Trigger Condition, which allows you to filter trigger events.
