Description

This endpoint allows you to send a WhatsApp template to multiple recipients in a single request. It implements an asynchronous pattern: when creating the send, it returns a bulk_send_id that you can use to check the progress of the send. The API automatically handles Meta’s rate limits based on the number’s tier, distributes the sends, and tracks the status of each individual message.

Send statuses

The bulk send status field can have the following values:
StatusDescription
QUEUEDSend created and queued for processing
PROCESSINGActively sending messages
COMPLETEDAll messages processed successfully
PARTIALProcessed with some failures
FAILEDSend failed completely
CANCELLEDSend cancelled manually
Use the Send status endpoint with the bulk_send_id to check progress in real time, including counters for sent, delivered, read, and failed messages.

​
Automatic deduplication

The API automatically removes duplicate phone numbers from the recipients list. The unique_recipients field in the response indicates the actual number of unique recipients that will receive the message, while total_recipients reflects the original count submitted.

​
