To access the REST API routes, you will first need to create a pair of API keys. These API keys are used to access the REST API routes as a specific user.
Navigate to the WooCommerce > Settings > License Manager > REST API keys. Here you will be presented with the following screen:
Overview of REST API keys
On this screen, press the “Add key” button at the top of the page. From here on, you will be redirected to the following form:
“Create REST API keys” form
All fields are required. The “Description” field provides a name for this REST API key pair, which should summarize what it is the keys are being used for. The “User” field is a searchable dropdown field which determines to whom these keys will be assigned to. The “Permissions” field grants the REST API keys either read, write, or read/write permissions.
After filling out the form and pressing the “Generate API key” button, you will be redirected to the following page:
REST API keys have been created
As the success message instructs, you should now store these keys somewhere safe, as this is the last time you will see the secret key. If you do not save the REST API keys, or lose them, you will not be able to recover them. Because the consumer secret is stored as a hash inside the database, it is impossible to revert. Should this occur, you will need to generate a pair of new REST API keys.
