bulksms_get_profileread-onlyShow the BulkSMS account: username, credit balance, credit limit, whether credit transfer is allowed, the daily message quota (size and remaining today) and the sender ids this account may use. Company and billing details are left out. BulkSMS REST: GET /profile.
bulksms_list_messagesread-onlyList sent (SENT) and received (RECEIVED) SMS messages, newest first by default. BulkSMS limits the window to the last 7 days unless submission_date_from is given. To page newest-first, pass before_id = the smallest id of the previous page; with sort_order ASCENDING pass after_id = the largest id of the previous page. REST: GET /messages with a `filter` built from the arguments.
bulksms_get_messageread-onlyGet one sent or received message by its id: body, recipient, delivery status, number of parts and credit cost. BulkSMS REST: GET /messages/{id}.
bulksms_list_repliesread-onlyList the received (RECEIVED) replies linked to a sent message id. Only messages sent with a REPLIABLE sender have linked replies. An empty list means none or an unknown id. BulkSMS REST: GET /messages/{id}/relatedReceivedMessages.
bulksms_list_blocked_numbersread-onlyList phone numbers the account may not send to (added via the API, by a recipient replying STOP, or by BulkSMS). To page, pass min_id = the largest id of the previous page + 1. BulkSMS REST: GET /blocked-numbers.
bulksms_list_webhooksread-onlyList the account's webhooks (name, trigger SENT/RECEIVED, active flag, invoke option). Only the host of each webhook URL is shown: the path and query can hold a secret. Read-only: webhooks are not changed by this server. BulkSMS REST: GET /webhooks.
bulksms_send_messagecan modifyWRITE: SENDS REAL SMS to real people and SPENDS CREDITS from the user's BulkSMS account; it cannot be undone or recalled. One message text to 1 to 10 phone numbers in international format (e.g. +447700900000). Cost = credits per message part x number of parts x number of recipients (about 1 credit per 160-character GSM part to a standard-route destination; the exact cost depends on the destination
bulksms_block_numbercan modifyWRITE: adds ONE phone number to the account's blocked list, so that no further messages are sent to it (a send to a blocked number fails with FAILED.BLOCKED and still costs credits). This API has no way to remove a block again: do it only when the user asks for it. BulkSMS REST: POST /blocked-numbers.
