I'm unable to connect to a freestanding instance of marketing cloud via API using XML. Getting 'invalid username, password, security token or locked out' error. the username, password and account are good, however I see no way to acquire the security token. We've reset passwords, created new users and no luck. The client does not have support services that include API, so no help there. Is the Security only applicable for accounts integrated with sales/service cloud? is there another way to connect with XML?
Common pitfalls when connecting to the SOAP-API are:
- You are using the wrong endpoint, that isn't the one for your instance/stack.
- Your user doesn't have the "API User" property enabled
