# Get Invocation Output

> Fetching the status and output of an invocation

Once an invocation has been initiated, you can fetch the status and output of it
using the ID. It is expected that an invocation will take time to finish. While it is
in progress, a `status` field will indicate it as `Pending` or `Running`. Once the invocation
has finished, the `status` will be set to `Complete`.

```
