This may be really useful for smarter configuration of the endpoint.
+== SNS FIFO
+
+SNS FIFO are supported. While creating the SQS queue you will subscribe to the
SNS topic there is an important point to remember, you'll need to make possible
for the SNS Topic to send message to the SQS Queue.
+
+This is clear with an example.
+
+Suppose you created an SNS FIFO Topic called Order.fifo and an SQS Queue
called QueueSub.fifo.
+
+In the access Policy of the QueueSub.fifo you should submit something like this
+
+[source,bash]
+-------------------------------------------------
+{
+ "Version": "2008-10-17",
+ "Id": "__default_policy_ID",
+ "Statement": [
+ {
+ "Sid": "__owner_statement",
+ "Effect": "Allow",
+ "Principal": {
+ "AWS": "arn:aws:iam::780560123482:root"
+ },
+ "Action": "SQS:*",
+ "Resource": "arn:aws:sqs:eu-west-1:780560123482:QueueSub.fifo"
+ },
+ {
+ "Effect": "Allow",
+ "Principal": {
+ "Service": "sns.amazonaws.com"
+ },
+ "Action": "SQS:SendMessage",
+ "Resource": "arn:aws:sqs:eu-west-1:780560123482:QueueSub.fifo",
+ "Condition": {
+ "ArnLike": {
+ "aws:SourceArn": "arn:aws:sns:eu-west-1:780410022472:Order.fifo"
+ }
+ }
+ }
+ ]
+}
+-------------------------------------------------
+
+This is a critical step to make the subscription work correctly.
+
+=== SNS Fifo Topic Message group Id Strategy and message Deduplication Id
Strategy
+
+When sending something to the FIFO topic you'll need to always set up a
message group Id strategy.
+
+If the content-based message deduplication has been enabled on the SNS Fifo
topic, where won't be the need of setting a message deduplication id strategy,
otherwise you'll have to set it.
