Managing shop keys
Keys are available in the shop. They allow secure data exchanges between the payment gateway and your merchant server. Each shop has its own keys, and for each integration mode:
Form API keys in redirection mode:
Keys can be viewed via the Settings > Shop > Keys tab.

In the test phases, a test key is generated by default. Click Regenerate a test key if necessary.
To go into production, you must first perform a number of tests.
Following these tests, the Generate production key button appears, allowing you to obtain the key.
See the article "How to switch my shop into production mode?" de la FAQ.
REST API keys and forms in embedded mode:
Keys can be viewed via the Settings > Shop > REST API keys tab.

For each use, there is a TEST key and a Production key.
Keys (called “passwords”) are used for calls to REST Web Services.
The public key is used for creating a payment form in the client’s browser.
The HMAC-SHA-256 key is used for verifying the authenticity of the data during the payment form return in the browser.
Following your test phases, the REST API button: Generate a new production password to obtain the production key.
