API Gateway -> SQS HTTP POST MessageAttributes - amazon-web-services

Question

I have an API gateway setup which sends to SQS which fires a Lambda, I am trying to pass message attributes to the SQS but when I hit the endpoint in postman I keep getting a 400 Bad Request.. what is the right way to send the attributes over a JSON POST body
here is body from postman (have tried a few options based on this link)
"message": "Message",
"MessageAttributes": {
"Name": "Name",
"Type": "String",
"Value": "my value"
}
}
Here is how API Gateway is configured

Answer 1

Incase someone stumbles on this later here is worked from the CDK side
let intergation = new apiGateway.CfnIntegration(this, 'Integration', {
apiId: props.httpApi.httpApiId,
payloadFormatVersion: '1.0',
integrationType: 'AWS_PROXY',
credentialsArn: apigwRole.roleArn,
integrationSubtype: 'SQS-SendMessage',
requestParameters: {
QueueUrl: sqsqueue.queueUrl,
MessageBody: '$request.body',
MessageAttributes: '$request.body.MessageAttributes'
}
})
new apiGateway.CfnRoute(this, 'Route', {
apiId: props.httpApi.httpApiId,
routeKey: apiGateway.HttpRouteKey.with('/url/foo', apiGateway.HttpMethod.POST).key,
target: `integrations/${intergation .ref}`
}).addDependsOn(intergation);
and the cloudformation
MessageBody: $request.body
MessageAttributes: $request.body.MessageAttribute
then in post man the POST body content type as application/json
{
"message": "Message",
"MessageAttributes": {
"Attributes": {
"DataType": "String",
"StringValue": "my value"
}
}
}
the lamba would log out both separate for each Record from the event body
Records: [
{
....
body: 'Message',
attributes: [Object],
messageAttributes: [Object]
}
]
}
the messageAttributes object from above:
{
Attributes: {
stringValue: 'my value',
stringListValues: [],
binaryListValues: [],
dataType: 'String'
}
}
This is using AWS API Gateway v2 HTTP API also
