What file format is required?

We prefer you use CSV files.

CSV files are preferred and return the best results. Tab delimited text files with a .txt extension are also accepted.

To minimize upload time, you can zip compress large files prior to uploading them. Zip archives should only contain a single file with a .csv or .txt extension.

For regular uploads, files should have a minimum of 25 records. Files uploaded through the API require only 1 record.
