Get account profile and credits
Show 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.
无需输入参数。
List messages
List 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.
typelimitafter_idbefore_idstatus_idsort_orderstatus_typesubmission_iduser_supplied_idsubmission_date_fromGet message
Get one sent or received message by its id: body, recipient, delivery status, number of parts and credit cost. BulkSMS REST: GET /messages/{id}.
message_id必填List replies to a sent message
List 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.
message_id必填List blocked numbers
List 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.
limitmin_idList webhooks
List 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.
无需输入参数。
Send SMS
WRITE: 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 and appears as creditCost on the sent messages afterwards). Messages longer than one part are concatenated up to max_parts parts (default 3). Non-GSM characters (emoji, accents outside GSM 03.38) are replaced by "?" unless auto_unicode is true, which sends Unicode (shorter parts, more credits). Messages to blocked numbers still cost credits. Only send what the user explicitly asked for, confirm the text and recipients first. No groups, no scheduling. Texts containing BulkSMS template placeholders such as {F0###}, {fn###} or {sn###} are rejected (they would merge contact data). BulkSMS REST: POST /messages.
to必填body必填frommax_partsauto_unicodeuser_supplied_idBlock a phone number
WRITE: 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.
