You can use an API to import existing keys into Tyk.

This example uses standard authorization header authentication, and assumes that the Dashboard is located at 127.0.0.1:8080 and the Tyk secret is 352d20ee67be67f6340b4c0605b044b7 - update these as necessary to match your environment.

To import a key called abc, save the JSON contents as token.json (see example below), then run the following Curl command:

curl http://127.0.0.1:8080/tyk/keys/abc -H 'x-tyk-authorization: 352d20ee67be67f6340b4c0605b044b7' -H 'Content-Type: application/json'  -d @token.json

The following request will fail as the key doesn’t exist:

curl http://127.0.0.1:8080/quickstart/headers -H 'Authorization: invalid123'

But this request will now work, using the imported key:

curl http://127.0.0.1:8080/quickstart/headers -H 'Authorization: abc'
