AWS1 input → 2 outputs

SQS Send

Sends a single message to an SQS queue (standard or FIFO).

Inputs

payload.queueUrl string: Overrides the Queue URL set in the node config.
payload.messageBody / payload.body string | object: The message to send. Objects are stringified automatically. If not set, falls back to the node's static Message Body, then to the entire msg.payload object.
payload.messageAttributes object: SQS MessageAttributeValue map, e.g. { Source: { DataType: 'String', StringValue: 'ehr-sync' } }.
payload.messageGroupId string: FIFO only — overrides the node config Message Group ID.
payload.messageDeduplicationId string: FIFO only — overrides the node config Message Dedup ID.

Outputs

Output 1 — Success

payload.success boolean: Always true.
payload.MessageId string: The AWS-assigned ID of the sent message.
payload.sequenceNumber string: FIFO queues only — the sequence number assigned by SQS.
sqs.operation string: "send"
sqs.queueUrl string: The queue that was sent to.

Output 2 — Error

payload.error string: Error message from AWS.
payload.errorType string: Human-readable error category (e.g. Queue Not Found, Auth Error).
payload.solution string: Suggested fix for the error.
payload.awsCode string: Raw AWS error code.

How to Use

Select an AWS config node (or create one with your AWS credentials/region).
Enter the Queue URL, or supply it at runtime via msg.payload.queueUrl.
Optionally set a static Message Body, or send the payload as-is / via msg.payload.messageBody.
For FIFO queues, set Message Group ID (required) and Message Dedup ID (unless content-based dedup is enabled on the queue).
Wire the output: Output 1 = success (msg.payload.MessageId), Output 2 = AWS error.

ConnectHealth Example

Publish a FHIR sync event for downstream processing:

msg.payload = {
  queueUrl: "https://sqs.us-east-1.amazonaws.com/123456789012/fhir-sync.fifo",
  messageBody: { patientRef: "Patient/epic-A-123", eventType: "updated" },
  messageGroupId: "epic-hospital-A"
};

// Output 1 on success:
msg.payload = {
  success: true,
  MessageId: "d6b3f1d2-...-6b1a",
  sequenceNumber: "18849...002"
}

Best Practices

Never place PHI directly in Message Attributes — attributes are metadata and may be logged by consumers; keep PHI in the message body only.
For FIFO queues, choose a stable Message Group ID (e.g. per hospital/tenant) to preserve ordering within that group.
Use Output 2 to wire an error-handling branch (e.g. log the error and retry or alert).

msg.payload = { queueUrl: "https://sqs.us-east-1.amazonaws.com/123456789012/fhir-sync.fifo", messageBody: { patientRef: "Patient/epic-A-123", eventType: "updated" }, messageGroupId: "epic-hospital-A" }; // Output 1 on success: msg.payload = { success: true, MessageId: "d6b3f1d2-...-6b1a", sequenceNumber: "18849...002" }
