Hello,
I'm trying to use logstasth http\_poller plugin to get some events from a rest API method.
Before calling the events API methods, I should call the login method and get a token from its response. While I use the events API, I have to provide the token I just got from the login method.
Can I have some example how to do it?

Here is an example
```
input {
http_poller {
urls => {
my-api-poller => {
method => get
cacert => "/home/my-user/my-ssl.io.cert.cer"
pool_max => 1
pool_max_per_route => 1
keepalive => true
automatic_retries => 1
socket_timeout => 60
url => "https://my-api-url"
headers => {
Accept => "application/json"
Authorization => "Bearer my-token"
}
}
}
request_timeout => 60
schedule => { every => "15m"}
codec => "json"
metadata_target => "my-assets"
}
}
```

thanks Yassine,
I have two methods to call:
1. Login method - which is givving me the token and its reponse headers. and then call the second method
2. GetEvents method - which is needed for the token from the Login method.
At your example:
1. Where is the login method call?
2. Where is the GetEvents method should be placed?
3. How can I pass the token from the login call to the GetEvents call?
4. 'my-token' - Am I need to use it somewhere?

in this case, you can use the input plugin http\_poller to get the token
then use that token with the [filter plugin http](https://www.elastic.co/guide/en/logstash/current/plugins-filters-http.html) to get your events

The input use http\_poller for authentification and getting a token
```
input {
http_poller {
urls => {
my-api-poller => {
method => get
cacert => "/home/my-user/my-ssl.io.cert.cer"
pool_max => 1
pool_max_per_route => 1
keepalive => true
automatic_retries => 1
socket_timeout => 60
url => "https://my-api-url"
headers => {
Accept => "application/json"
Authorization => "Basic username:password"
}
}
}
request_timeout => 60
schedule => { every => "15m"}
codec => "json"
metadata_target => "my-token"
}
}
```
In the filter section of your LS config, you need to access the field `my-token` et get the token from the response
Then use this token as part of` http filter`
```
http {
body_format => "json"
follow_redirects => false
body => {
"attribute" => "%{[attribute_value]}"
}
url => "my-api-url/GetEvents"
verb => "POST" --- or GET !
headers => ["Authorization", "Bearer ${My-token}"]
target_body => "[@metadata][api_response]"
target_headers => "[@metadata][api_headers]"
}
```
...
Hope this can help
