# Frequently Asked Questions

## Can I use apps that don’t have a MESA connector?

If the service you are using has a publicly-available HTTP(S) endpoint, you can use our [API tool](/content/connect/api/index.html). Here is more information about the [API tool](https://docs.getmesa.com/tools/api).

If the desired service requires OAuth connection, then a out-of-the box solution does not exists at this time. If this is the case, don't give up yet! We may be able to custom build a solution for you. You can send our team an email mentioning the desired service connection at mesa@getmesa.com.
