Filter i tried,
filter {
    grok {
        match => { "message" => "%{GREEDYDATA:wd}" }
    }
    json{
        source => "wd"
        target => "js"
    }
    mutate {
        add_field => { "t1" => "%{[js][logEvents][message]}"}
    }
}

You aren't likely to get any response if you simply post a json blob into your body like that.

What have you tried so far?
What problems are you facing?

i tried

filter {
grok {
match => { "message" => "%{GREEDYDATA:wd}" }
}
json{
source => "wd"
target => "js"
}
mutate {
add_field => { "t1" => "%{[js][logEvents][message]}"}
}
}

@Piyush_Sonigra

grok {
match => { "message" => "%{GREEDYDATA:wd}" }
}
json{
source => "wd"
target => "js"
}

Using grok like that does not make any sense. It is clearer and cheaper to do

json { source => "message" target => "js" }

If you want to extract all the messages from the logEvents array I think you will need to use ruby.

    ruby {
        code => '
            a = []
            event.get("[js][logEvents]").each { |x|
                a << x["message"]
            }
            event.set("t1", a)
        '
    }

will get you

        "t1" => [
    [0] "(d7b307ed-4c36-11e9-bb5e-b7d673a) Extended Request Id: W6sqaGhwDoEFavA=",
    [1] "(d7b307ed-4c36-11e9-bb5e-b7d673a) Verifying Usage Plan for request: d7b307ed-4c36-11e9-bb5e-b7d673a. API Key:  API Stage: x63d3nk/live",

Thanks @Badger

i have parsed using json,split and used value using mutate https://www.elastic.co/guide/en/logstash/current/plugins-filters-split.html

filter {
json {
source => "message"
}
split {
field => "logEvents"
}
mutate {
add_field => ["time", "%{[logEvents][timestamp]}"]
}
date {
locale => "en"
timezone => "UCT"
match => [ "time", "MMM dd yyyy HH:mm:ss","MMM d yyyy HH:mm:ss", "ISO8601" ]
}
}
