I know it might not be the best case, but due to some limitations, I have to do, THe API call will need to be triggered through GitLab. The service is running in a place that only gitlab is able to access. My expectation is the query toward the service , query per min < 100. however, as long as it can be pushed out whenever it needs to be done, it will be good.

Gitlab will be pushed out to the service, and GitLab hold the config which can do that.

Is this a good idea? or are any other constrain you can suggest?

Thanks
