Hi, 

I'm looking for a way to trigger http node/API call based on a previous node result. In particular, if the column in the database query is empty (any predefined value), then don't trigger http node and subsequent flow. So far I didn't find the method or node which can be passed as an argument to the http node as a trigger. I know there is another way through scheduler where one scheduler can be invoked on success of another flow, but I need to do this within one flow.

Thanks,

IC

You could use the Meta Check Node.

Insert a Transform node after the node that is returning the result to be checked and configure it with some logic that only outputs a record if the required condition is met. e.g. given the following Test Results output

The following logic in the Transform node only outputs a single record if the test condition is met:

The Meta Check node is configured to expect a minimum of one input records for the test to be successful and to enable node(s) connected to it's output clock pin if the test is successful:

A Run Dependency is used to specify when the HTTP node should run:

This is great, thank you!
