HTTP call error to shopify fails when sending array in json request

ashensha90 · ‎12-03-2022

This is an http post response to create a new shopify blog with metadata values.

blog := Blog{
        Title:           fileNameWithoutExtSliceNotation(doc.Name()),
        Template_suffix: "hit_parader_issue_template",
        Metafields: []BlogMeta{
            {
                Key:       "filter_tag_list",
                Value:     "Popular",
                Type:      "single_line_text_field",
                Namespace: "global",
            },
        },
    }

        blogJSON, err := json.Marshal(blog)
        blogReq, err := http.NewRequest("POST", newBlogQuery, bytes.NewBuffer(blogJSON))
        blogReq.Header.Add("X-Shopify-Access-Token", TOKEN)
        blogReq.Header.Add("Content-Type", "application/json")

resp1, err := client.Do(blogReq)

my structs are like below

type Blog struct {
    Title           string `json:"title"`
    Template_suffix string `json:"template_suffix"`
    Metafields      []BlogMeta
}

type BlogMeta struct {
    Key       string
    Value     string
    Type      string
    Namespace string
}

im getting an error saying

{"errors":{"blog":"Required parameter missing or invalid"}}

These are my blog metafield definitions.

I have all the necessary fields listed in the following api call. Please help.

Im using below API

https://shopify.dev/api/admin-rest/2022-10/resources/blog#post-blogs

NOTE: the API documentation says that I need to present a array for the metafields. But I think my code is correct. IS there something im missing? Any help would be appreciated.
