Hi,
Thank you for reaching out to our API support team.
Since you mentioned you are using the REST API, you may refer to this
REST interface authentication guide for the complete steps that you need to follow in order to acquire the required credentials and successfully authenticate your requests. Also, this
section discusses how you can generate a new access token for use in your API calls.
Best regards,
