I found [the docs on relations](https://the.fibery.io/@public/User_Guide/Guide/Custom-App-REST-Endpoints-272/anchor=Relations--3468502a-5a32-4179-88e6-02f547969e13) for custom integrations but it doesn’t have an example of the required schema for a many-to-many relation. I’m not sure what’s required on either property to make it all work. Does anyone have an example schema of many-to-many relations?

It’s pretty much the same as the many-to-one schema, e.g.

```auto
"repositoryIds": {
      "type": "text",
      "name": "Repository Ids",
      "relation": {
        "cardinality": "many-to-many",
        "name": "Repositories",
        "targetName": "Pull Requests",
        "targetType": "repository",
        "targetFieldId": "id"
      }
    }

```

OK, is it required to have the inverse of this on the Repository as well?

Nope. Just define it from one side of the relation
