# Send SQS message

Canonical URL: https://docs.fuse.init.inc/integrations/aws/actions/sqs.messages.send

Send a message to an SQS queue URL of the form https://sqs.<region>.amazonaws.com/<12-digit-account>/<queue-name>. Caps body plus up to ten string attributes at 1 MiB. FIFO queues require message_group_id and reject per-message delay; standard queues reject message_deduplication_id. Unsafe with one SDK attempt. Excluded from MCP. Requires sqs:SendMessage.

Action ID: `sqs.messages.send`
Provider: AWS (`aws`)
Contract version: 1
