How to setup custom endpoint that executes stored GraphQL query

[prineshaz]

I've looked in the docs and discussion and unable to find an answer to this.

Is it even possible? Say for instance, i have endpoint

/api/my-endpoint/arg1=arg1&locale=en

Im wondering if this can then be routed to a GQL query that is stored in code (whereby i pass arg1 & locale ) eg:

query MyCustomQuery($arg MY_TYPE, $localeL LOCALE = EN ) {
  Collection(draft: false) {
    docs {
      title
    }
  }
}

Apologies if this isnt clear. I need it this way as my team and company expect to PayloadCMS to slot into our existing backend where the incoming args and params are set. I've looked into the REST interface briefly but unsure if this is possible either.

Thanks!
