Hello,
I have a set of http API one of them with "no time" data based , the fields are ID, geo location(lat,lon) and others data.
The ID is the key to access another API, (time based) , our target is to send all data from APIs to ES, in each line
For Example
API ONE respond :
{"dte":[{"id":" **136**","latitud":"-35.760761","longitud":"-71.574215","elevacion":"150"}]}
API2: [http://api2?dteid=](http://api2?dteid=) **136** &user ...... and answer
{"values":[{"val1":"30.5","val2":"33.0"},{"val1":"20.3","val2":"24.4"}..........]
We need leave in ES
{"id":" **136**","latitud":"-35.760761","longitud":"-71.574215","elevacion":"150","val1":"30.5","val2":"33.0"}
{"id":" **136**","latitud":"-35.760761","longitud":"-71.574215","elevacion":"150","val1":"20.3","val2":"24.4"}
...........
Is posible resolve it with logstach or we need join the info before to one file, for example, and then up the file to
ES.
I hope explain me clearly
Thanks a lot.

To my knowledge, with logstash, you can't call a first API, and then call a second API using data returned by first API.
So, to do that, I invite you to use exec input, where you chain curl requests.
When you receive first response, you extract interesting data to use it into second curl request.
