Link preview data is not always available—sadly.
Maybe you need to get the header image from a WordPress post, or you’re building a Notion database with links, and would like to enrich it? If so, then this guide is for you. Here’s a few easy steps on how to set that up, with the help of a free API.
This is the data that we’ll retrieve:
1) Creating an API key
Scouring the internet, I found a couple of APIs that return link preview data. The one I landed on is called URL Meta
Create an API key on https://urlmeta.org/.
Once an account has been created, you’ll be able to copy your API key:
2) Base 64 encode your credentials
As per the API docs, we’ll need to base encode the:
And use the Authorization Basic header (more on that later). We’ll head to this link first:
Then fill out the following details—and take these steps:
- Add your email address, followed by a colon, then the API key
- Click on the ENCODE button
- Copy everything that appears in the box
3) Setting up a custom request in Webhooks by Zapier
Now comes the easiest part! Here’s how it’s going to look:
- We’ll select the Custom Request in Webhooks by Zapier action
- Select GET
- Add the URL https://api.urlmeta.org/?url=XXX (and replace XXX with a mapped object from a previous step/or hard code it by manually typing something out)
- Add the `Authorization` header, then use `Basic baseEncodedValueHere`)
- Ready for testing!
And there you have it! We have a solution to dynamically retrieve link preview data.
Hope that helps!
