Description

The request-id Plugin adds a unique ID to each request proxied through APISIX.

This Plugin can be used to track API requests.

:::note

The Plugin will not add a unique ID if the request already has a header with the configured header_name.

Attributes

Name	Type	Required	Default	Valid values	Description
header_name	string	False	“X-Request-Id”		Header name for the unique request ID.
include_in_response	boolean	False	true		When set to true, adds the unique request ID in the response header.
algorithm	string	False	“uuid”	[“uuid”, “nanoid”, “range_id”]	Algorithm to use for generating the unique request ID.
range_id.char_set	string	False	"abcdefghijklmnopqrstuvwxyzABCDEFGHIGKLMNOPQRSTUVWXYZ0123456789	The minimum string length is 6	Character set for range_id
range_id.length	integer	False	16	Minimum 6	Id length for range_id algorithm

Enable Plugin

The example below enables the Plugin on a specific Route:

:::note You can fetch the admin_key from config.yaml and save to an environment variable with the following command:

admin_key=$(yq '.deployment.admin.admin_key[0].key' conf/config.yaml | sed 's/"//g')

:::

curl http://127.0.0.1:9180/apisix/admin/routes/5 \
-H "X-API-KEY: $admin_key" -X PUT -d '
{
    "uri": "/hello",
    "plugins": {
        "request-id": {
            "include_in_response": true
        }
    },
    "upstream": {
        "type": "roundrobin",
        "nodes": {
            "127.0.0.1:8080": 1
        }
    }
}'

Example usage

Once you have configured the Plugin as shown above, APISIX will create a unique ID for each request you make:

curl -i http://127.0.0.1:9080/hello

HTTP/1.1 200 OK
X-Request-Id: fe32076a-d0a5-49a6-a361-6c244c1df956

Delete Plugin

To remove the request-id Plugin, you can delete the corresponding JSON configuration from the Plugin configuration. APISIX will automatically reload and you do not have to restart for this to take effect.

curl http://127.0.0.1:9180/apisix/admin/routes/5 \
-H "X-API-KEY: $admin_key" -X PUT -d '
{
    "uri": "/get",
    "plugins": {
    },
    "upstream": {
        "type": "roundrobin",
        "nodes": {
            "127.0.0.1:8080": 1
        }
    }
}'
