Which authentication method should you use?
  • Basic Auth - Use this if you are building integrations for your own shop. This is the most common use case and what most developers need. Simply create API credentials and include them with each request.
  • OAuth - Use this only if you are building an app that will be used by multiple different shops (e.g., a third-party integration that other Fourthwall creators will install). See the OAuth guide for details.
The simplest way to authenticate is with a shop level API key. This key will give you unrestricted access to all API endpoints for your shop.

​
Getting credentials

The creation of API credentials is reserved for users with the SUPER ADMIN role.
  1. Navigate to For developers to create an API user.
  2. If API credentials haven’t been generated yet, you will find a “Create API User” button under the “Open API” section. Click on it, and shortly after, the Username and Password for the Open API User will be provided.
Keep your API credentials confidential and do not share them with unauthorized personnel. These credentials grant access to sensitive data and actions within our system. Always use HTTPS/SSL for encrypted communication when making API requests.

​
Authorizing with credentials

After Open API User was created, you can authorize your request by using Basic Access Authentication. This can be achieved by constructing an Authorization header with the format Basic base64-encoded-username-and-password. The base64-encoded credentials should be passed with each request to gain access to the protected resources.
