The below Templater command will grab your raindrop links and then filter for those made today. You can adjust the date matching to grab yesterday, etc.
You'll need a raindrop API test token for your account by creating an app. You can do that here:
<%*
const TEST_TOKEN = $put_token_here
const output = await fetch("https://api.raindrop.io/rest/v1/raindrops/0",
{headers: {"Authorization": `Bearer ${TEST_TOKEN}`}})
.then(res => res.json())
.then(json => json.items
.filter(item => moment(item.created).format("YYYY-MM-DD") === moment().format("YYYY-MM-DD"))
.map(item => `- [${item.title}](${item.link}) ${item.tags.map(tag => `#${tag}`).join(" ")}`)
)
tR += output.join("\n")
%>
