Postman AWS S3 snapshot request Elasticsearch - elasticsearch

Question

Hello I need some help with sending a PUT request to my ElasticSearch on AWS to create a snapshot in a S3 bucket, with POSTMAN.
I have created a S3 bucket called cb-search-es-backup.
I've created a role, and a policy for S3 (see:this post of mine for the steps I've taken).
REQUEST URL https://myelasticsearchendpoint.eu-west-1.es.amazonaws.com/
REQUEST METHOD: PUT
BODY : RAW / json
{
"type": "s3",
"settings": {
"bucket": "cb-search-es-backup", // my bucketname
"region": "eu-west-1", // region
"role_arn": "arn:aws:iam::12345676890:role/Role_ES_TO_S3" // my role arn
}
}
I've also tried the authorization type: 'AWS Signature', with access and secret key filled in.

It looks like you are not passing AWS credentials with this request.
There is a detailed guide how to make a Postman request with AWS authentication here: Use Postman to Call an API.
Your Postman window might look like this:
To do the same from python please check out Sample python client section of this documentation page, note that AWS4Auth object is created and it's passed as auth parameter to requests.put():
credentials = boto3.Session().get_credentials()
awsauth = AWS4Auth(credentials.access_key, credentials.secret_key, region, service, session_token=credentials.token)
# Register repository
path = '_snapshot/my-snapshot-repo' # the Elasticsearch API endpoint
url = host + path
payload = {
...
}
headers = {"Content-Type": "application/json"}
r = requests.put(url, auth=awsauth, json=payload, headers=headers)
