Max records to return (1-100, default 20)
offsetinteger
Skip first N records for pagination (default 0)

purchase_credits

Start a prepaid credit purchase. If the request is authenticated, credits will be loaded into the authenticated account after PayPal payment. If the request is not authenticated, provide email and name to create a new prepaid account (or load credits into an existing one with the same email). Returns a PayPal payment URL the user must visit to complete the purchase.

Parameters (3)

service_typestringrequired
Purchase option. One of: prepaid10 (100 pages, $9.95), prepaid20 (250 pages, $19.95), prepaid50 (800 pages, $49.95), intprepaid50 ($49.95 international balance), intprepaid100 ($99.95 international balance), intprepaid200 ($199.95 international balance).
emailstring
Required when the request is not authenticated. Used to create or load an existing prepaid account.
namestring
Required when the request is not authenticated. Account holder name.

send_free_fax

Send a free fax to a US or Canada number (no account required). Limited to 3 pages total and 2 sends per email/IP per day. Returns a job_id immediately, but the fax does NOT send until the sender clicks a confirmation link emailed to sender_email. The daily-limit check happens at click time, not at submission — a submitted fax may still be rejected if the limit is hit by then; the agent can detect this by calling check_fax_status after the user reports clicking the link. If the document exceeds the free page limit, the response will suggest using purchase_credits to buy a prepaid account.

Parameters (11)

fax_numberstringrequired
Destination fax number (10 digits, US or Canada).
sender_namestringrequired
Sender's name (required).
sender_emailstringrequired
Sender's email address. A confirmation link will be sent here; the fax does NOT actually send until the user clicks that link.
receiver_namestringrequired
Receiver's name (required).
sender_companystring
Sender's company (optional).
sender_faxstring
Sender's fax number (optional).
receiver_companystring
Receiver's company (optional).
