Yes! Please reach out to your Customer Success Manager or customersuccess@credly.com and we would be happy to set up a Sandbox account for your organization.
If you organization already has a Sandbox account, an administrator for your organization can invite you to have access to the testing site.
Please keep in mind that the sandbox and production environments are completely separate so the work you do in the sandbox cannot be automatically copied over to production. It's also important to note that the sandbox is for TESTING. To ensure data privacy, please do not use real earner data in the sandbox.
If you are using the sandbox, please consult this Getting Started Guide. You might also find these samples helpful.
