Create pull request automatically when a commit is made to specified branch

[Esther Strom]

We have branch permissions set up on our two main branches (develop and master.) 

We recently started using a plugin called qTest Scenarios that allows members of our extended teams to create BDD feature files from within a Jira ticket. The plugin would then automatically create a commit in the configured branch.

We don't want to open up branch permissions on develop/master so that anyone can write to them, so we've created a separate branch that everyone on the team *can* write to, which is the one that's connected to the plugin configuration.

The problem we're running into is how to monitor things to make sure that features created this way get reviewed and merged into develop as necessary. 

Is there any way to set up Bitbucket Cloud so that a pull request is automatically created when a commit is made to a specified branch? I'm open to using webhooks or pipelines, if someone can point me in the right direction.
