Method API call MethodAPIActionSendEmailV3 is failing right now. Other API calls are still successful using the same account/user/pass.
Here's the response I'm getting:
MethodAPI response = "The API failed to process the request. Please review your code before trying again."
No code changes have occurred.
Thanks for reaching out. We are currently investigating this issue as to what might have happened to the MethodAPIActionSendEmailV3 endpoint. At this point it looks like the issue is specific to that endpoint.
Hey Blake - the servers were updated with a security patch, and for some reason this seemingly has affected nothing except for that one API endpoint. We're going to look into it in Monday when everyone is back in the office. But in the meantime we have rolled back the security patch, and will reapply it next week. In the meantime, you should be back up and running. Many apologies for the disruption.
