# Can I Use Apps That Don't Have a MESA Connector?

Connect a service without a MESA connector using the API tool when it has a public HTTP endpoint, or ask the team about a custom build for OAuth services.

If the service you are using has a publicly-available HTTP(S) endpoint, you can use our [API tool](https://www.getmesa.com/connect/api). Here is more information about the [API tool](https://docs.getmesa.com/tools/api/). \
\
If the desired service requires OAuth connection, then an 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.
