How do I invalidate response cache?

I like that I can cache responses, but sometimes I need to delete/add/edit a record which invalidates the cache, but the cache does not refresh until TTL runs out.
How do I invalidate a response cache?

Sean Montgomery

You can't invalidate an existing cached response, but you can add a cache busting input argument.

For example, you could keep a version counter that changes when you want to guarantee a new fresh result.

/api/test?v=1
/api/test?v=2
/api/test?v=3

 Okay, yeah I see what I could do, thanks.👍

@Sean Montgomery Thank you Sean.

I am trying to implement this at the moment and I was wondering if you could provide more details as to how to implement this?

I am familiar with Xano's basics and I have an initial understanding of what you are suggesting. However, I'd appreciate it if you can provide some brief steps to elaborate a bit.

For instance,

• Do I need to create a certain input field? Is this then checked within the function or is the change in the endpoint URL by itself is enough?
• What's a good practical way to make sure it does reset and that the v is not previously used?

Many thanks!

@Abdulrahman Hariri Yeah, you need to use an Input to do that.
