}queue:SendMessage. See QUEUE permissions for the full list, what each one covers, and an example policy.Authorizations
An OAuth 2.0 bearer token, sent as Authorization: Bearer <token>.
This is the recommended way to authenticate.
Get one by exchanging a service account's access key pair at
POST /v1/oauth/token with grant_type=client_credentials. It is the
standard client-credentials grant, so any OAuth-aware library will
obtain and refresh it for you.
curl -s -u "$KEY_ID:$SECRET" -d grant_type=client_credentials \
https://iam.basaltic.sh/v1/oauth/token
Tokens last an hour by default. The same access key pair is separately your AWS SigV4 credential for the S3-compatible object endpoint, which speaks nothing else.
Path Parameters
"a1b2c3d4-5e6f-4a7b-8c9d-0e1f2a3b4c5d"
Body
The payload. Counted against the queue's max_message_bytes together with the attributes.
"{\"order_id\":\"A-1001\"}"
Typed attributes carried alongside the body. At most 20; values at
most 1024 characters. Binary values are standard base64. The
queue never coerces a value — it only checks the value is
representable as the declared type.

{
"severity": { "type": "String", "value": "critical" },
"attempt": { "type": "Number", "value": "2" }
}
Overrides the queue's default for this message. Rejected on FIFO queues, where it would let a later message become visible before an earlier one in the same group.
0 <= x <= 9000
Required on FIFO queues, rejected on standard ones. Messages sharing a group are delivered in order, and a group's next message is withheld while an earlier one is in flight.
128"customer-42"
FIFO only. A repeat within five minutes is suppressed and the
original message's id is returned. Omit on a queue with
content_based_deduplication to derive it from the body.
128"order-A-1001"
Response
Message enqueued. On a FIFO queue with a live deduplication
entry the send still succeeds and duplicate is true, naming
the message the original send produced.
