Is the issue that it’s not possible, or that it’s not possible in Backendless?
I’m trying to set the FB meta tag to an image dynamically. As I understand it, FB doesn’t process JS, which was my first idea. I need another way to dynamically set an image.
A render link directly returns an image (JPEG) the same way a static image is returned from an URL. This means you can use a render link in all places that accept an image from an URL.
You can use a render link in places like the <img> element’s path, meta tags (Twitter card, the Open graph), email, or even a spreadsheet. Also, you can open a render link directly in your browser and download a rendered image manually.
This is exactly what I want to do, but using logic from my Backendless app.
I ask my colleagues, and you were correct. You couldn’t do it in Backendless API Services - because we always return an ‘application/json’ response type.
As for the link which you provided. Yes, you’re right, it’s generally possible, but we can’t provide you examples/advices on how to do it easily.
