Hello @LEMESSAGER ENZO
Welcome to our forum and thank you for trying Cognitive Service.
To find your key and endpoint information, you need to go to your resource in Azure Portal first- https://portal.azure.com/
Then you need to navigate to your Cognitive Service resource/ Face resource in the search box you created as below screenshot, when you arrived in your resource page, click "Keys and Endpoint", giving Face resource as an example:
Then you can get your Key and Endpoint information as below. If you created a Cognitve Service resource, it's the same process, just go to that resource.
You can find your key and endpoint in the resource's key and endpoint page, under resource management.
If you did not creat any resource for this, it's easy to create one,
First you need to have a Azure subscription - Create one for free - https://azure.microsoft.com/free/cognitive-services/
Once you have your Azure subscription, create a Face resource in the Azure portal to get your key and endpoint. After it deploys, click Go to resource.
You will need the key and endpoint from the resource you create to connect your application to the Face API.
You can use the free pricing tier (F0) to try the service, and upgrade later to a paid tier for production.
I hope this helps, please let me know if you need further help.
Regards,
Yutong
