Import contacts from a CSV file
Accepts a CSV file of up to 2 MB and 5,000 rows, uploaded as the multipart field file. The header row names the columns; first_name, last_name, email, phone, status and source are read and other columns are ignored. The file must be UTF-8 text; other encodings are refused rather than converted. Rows that fail, such as a malformed email or a value over its length limit, are reported on the import. Returns at once with a pending import that a background job processes. Finished imports keep their counts and rejected-row reasons but not the uploaded rows.
