end
elc -> fe : return the tracking response
deactivate elc

## 3pl aggregator

participant "everpro" as evp
participant "evm-3pl-client-gateway" as gateway
participant "evm-3pl-auth" as auth
participant "evm-3pl-aggregator" as aggregator
participant "3PL" as 3pl

== authentication ==
evp -> gateway : hit "/v1/authentication" to get the bearer token
activate gateway
gateway -> auth : validate the user credential
activate auth
auth -> gateway : return the access token
deactivate auth
gateway -> evp : return the access token
deactivate gateway
== tracking ==
evp -> gateway : hit "/v1/tracking/:awb" with the token
activate gateway
gateway -> gateway : validate token
gateway -> aggregator : request tracking for specific awb
activate aggregator
aggregator -> 3pl : track the awb
3pl -> aggregator : return the tracking history
aggregator -> aggregator : build the tracking response
note left
    add podReceiverName
endnote
aggregator -> gateway : return the tracking response
deactivate aggregator

deactivate eu
elc -> fe : return the file link
deactivate elc

## backfill proof of delivery

actor "user" as u
participant "n8n" as n8n
database "popaket_logistic" as db
participant "evm-3pl-client-gateway" as evm

u -> n8n : run the workflow
activate n8n
n8n -> db : get empty receiver_name from table proof_of_delivery
db --> n8n
loop
    n8n -> evm : track the order to get the podReceiverName
    evm --> n8n : return tracking
    n8n -> db : update the receiver name
end
n8n -> u : finish
deactivate n8n
