What you use
The API key must be allowed to access the
projectId in your request. A key can be limited to
selected projects or allowed across all projects in your organization. If the key is valid but does
not have access to the requested project or scope, the API returns 403.
Create an API key
- Create an account or sign in to the Incarts dashboard.
- Open
Settings>API Keys. - Create a key for your integration.
- Select the project access and scopes this key should use.
- Copy the API key when it is shown. Incarts only shows the full key once.
- Store the key server-side and send it in the
X-Incarts-API-Keyheader.
