API Changelog: March 1, 2025

RSS feeds just got smarter! Now you can attach metadata to your feeds and have it show up in your emails. Need to mark which site a feed is coming from or add some extra context? We've got you covered.

We added a metadata field to the RSS feed endpoints. It's just a simple key-value dictionary where both keys and values are strings.

You'll find the new field in:

• ExternalFeed (when you fetch a feed)
• ExternalFeedInput (when you create a feed)
• ExternalFeedUpdateInput (when you update a feed)

Here's a quick example:

{
  "url": "https://example.com/feed",
  "behavior": "create_draft",
  "cadence": "every",
  "subject": "New post: {{ item.title }}",
  "body": "Check out my new post: {{ item.url }}",
  "label": "My blog feed",
  "metadata": {
    "source": "blog",
    "category": "tech"
  }
}

Once you've set this up, just use the metadata values in your templates like any other variable.

Don't worry - this change won't break any of your existing integrations.
