Hello team -

We have an use case where we need to get events using REST api. REST api call is protected with authorization token which we generate using a url which is a combination of some parameters.

Can we create input configuration for this kind of setup?

Thanks  
Akhil

You cannot do that using an input. You may be able use a generator input to create a dummy event and then add fields to it using an http filter.

I'm using http\_poller to use POST request. It is giving error with the body.

I added body as below:

body =\> '{ "grant\_type":"client\_credentials","scope":"domain" }'

Error I'm seeing after running it as Bad request: 400

"message" =\> "Parameter conditions "grant\_type" not met for actual request parameters: { "grant\_type":"client\_credentials","scope":"domain" }={}",

Please suggest corrections.
