Licence authentication (beginner)

[imperium85]

Hi All,
I've never worked with licensing and I'm trying to achieve a simple task. (so it might be a stupid question) I have a small Android app, I want to send out a license key to the end user (demo valid for 24 hours and max 10 devices can activate it)
I was going to use this Licence authentication:
curl -X POST https://api.keygen.sh/v1/accounts/demo/machines \ -H 'Content-Type: application/vnd.api+json' \ -H 'Accept: application/vnd.api+json' \ -H 'Authorization: License C1B6DE-39A6E3-DE1529-8559A0-4AF593-V3' \ -d '{ "data": { "type": "machines", "attributes": { "fingerprint": "4d:Eq:UV:D3:XZ:tL:WN:Bz:mA:Eg:E6:Mk:YX:dK:NC", "platform": "macOS", "name": "Office MacBook Pro" }, "relationships": { "license": { "data": { "type": "licenses", "id": "4097d726-6cc5-4156-8575-3a96387e19b4" } } } } }'
But how the license ID will be different when I create a new license so how should I know what license ID i need to include in here without sending it to the user?
Also the fingerprint will be automatically stored in keygen and attached to the license so the count from 10 will go down to 9 devices being allowed to activate?

Thank you!

I just found the answer, i get the license id with the license validation.

Yep — exactly. It's been a good way to force people to validate first before performing possibly superfluous actions like activation — because after all, the machine being activated could already be activated!
