Go JSON:API (google/jsonapi) Pagination Example

Can someone show an example of how to output pagination links in the response using google/jsonapi? I've tried a couple approaches and none seems to work. I can directly output the object or an array of objects using MarshalPayload() and add links to the nodes by using the Linkable interface. I haven't yet seen an interface for the top level object so this is my current implementation.

		resp := map[string]interface{}{
			"data": users,
			"links": jsonapi.Links{
				"next": "next/2",
			},
		}

		c.Response().Header().Set(echo.HeaderContentType, jsonapi.MediaType)
		err = jsonapi.MarshalPayload(c.Response(), resp)
		if err != nil {
			return echo.ErrInternalServerError
		}

Which is complaining that:
models should be a struct pointer or slice of struct pointers. The output I'm looking for is something similar to the one on the JSON:API Homepage. For example:

{
  "links": {
    "self": "http://example.com/articles",
    "next": "http://example.com/articles?page[offset]=2",
    "last": "http://example.com/articles?page[offset]=10"
  },
  "data": ...<snipped>
}

TIA

I think the issue is with your resp Map. That needs to be a struct. So you would need something like this:

type Resp struct {
    Data []String `jsonapi:...`
    Links []Link `jsonapi:...`
}

resp := new (Resp)

//here add your values to resp
//like: resp.Data = users 

c.Response().Header().Set(echo.HeaderContentType, jsonapi.MediaType)
err = jsonapi.MarshalPayload(c.Response(), resp)
if err != nil {
    return echo.ErrInternalServerError
}

UPDATE:

Here's my sample code:

type User struct {
	ID   int    `jsonapi:"primary,user"`
	Name string `jsonapi:"attr,name"`
}

type Articles struct {
	Users []*User `jsonapi:"relation,users"`
}

Handler function: (I didnt add any error handling, but you should)

func (env *Env) TryJSONAPI(response http.ResponseWriter, request *http.Request) {
	resp := []*User{
		{ID: 3, Name: "username1"},
	}
	p, _ := jsonapi.Marshal(resp)
	payload, _ := p.(*jsonapi.ManyPayload)
	payload.Links = &jsonapi.Links{
		"self": fmt.Sprintf("https://example.com/articles"),
		"next": fmt.Sprintf("https://example.com/articles?page[offset]=%d", 2),
		"last": fmt.Sprintf("https://example.com/articles?page[offset]=%d", 10),
	}
	if err := json.NewEncoder(response).Encode(payload); err != nil {
		//handle error
	}
}

Output:

{
  data: [
    {
      type: "user",
      id: "3",
      attributes: {
        name: "username1"
      }
    }
  ],
  links: {
    last: "https://example.com/articles?page[offset]=10",
    next: "https://example.com/articles?page[offset]=2",
    self: "https://example.com/articles"
  }
}
