Question

How do I connect multiple sources to Amazon Kinesis Firehose?

Product

Twilio Segment

Environment

Segment Console

Answer

If you have multiple Segment sources sending data through Kinesis Firehose, you can handle authentication in two ways:

Attach multiple sources to your IAM role

Add each source's Secret ID (found in your destination settings) to the IAM role so Firehose can accept data from all of them.

Use Segment Workspace ID as your Secret ID

If you have many sources, you can use a single Secret ID (your Workspace ID) for all sources, avoiding the need to update the IAM role for each one.
