Add src/config attribute to amp-story-auto-ads element #34192
Description
As a developer I want to pass the JSON configuration object as an external path.
For example:
instead of
<amp-story-auto-ads>
<script type="application/json">
{
"ad-attributes": {
"type": "doubleclick",
"data-slot": "MY DATA SLOT"
}
}
</script>
</amp-story-auto-ads>
I want to be able to write
<amp-story-auto-ads src=URL_TO_JSON>
</amp-story-auto-ads>
Just like amp-analytics element have a config attribute
<amp-analytics
config="https://example.com/analytics.account.config.json"
></amp-analytics>
