Retrieve the publication fields defined for the workspace. Publication fields hold a value per publication that content can reference through a merge tag. Archived fields are excluded unless the `status` parameter asks for them. Requires an API key with access to every publication in the workspace. Reference: https://developers.beehiiv.com/api-reference/publication-fields/index ## Authentication - `Authorization` header (bearer token, required) — Bearer authentication of the form `Bearer `, where token is your auth token. ## Request ### Query parameters - `limit` (integer, optional) — A limit on the number of objects to be returned. The limit can range between 1 and 100, and the default is 10. - `cursor` (string, optional) — **Cursor-based pagination (recommended)**: Use this opaque cursor token to fetch the next page of results. When provided, pagination will use cursor-based method which is more efficient and consistent than offset-based pagination. - `page` (integer, optional) — **Offset-based pagination (deprecated)**: Page number for offset-based pagination. Please migrate to cursor-based pagination using the `cursor` parameter. If not specified, results 1-10 from page 1 will be returned. - `status` (enum, optional) — Filter fields by whether they have been archived. Defaults to `active`. - Allowed values: `active`, `archived`, `all` ## Response ### 200 OK - `data` (list of PublicationField, required) — An array of publication fields. - `limit` (integer, optional) — The limit placed on the results. If no limit was specified in the request, this defaults to 10. - `has_more` (boolean, optional) — **Cursor pagination only**: Indicates whether there are more results available after the current page. Only present when using cursor-based pagination. - `next_cursor` (string, optional) — **Cursor pagination only**: The cursor token to use for fetching the next page of results. This will be null if has_more is false. Only present when using cursor-based pagination. - `page` (integer, optional) — **Offset pagination only**: The page of results returned. Only present when using the deprecated `page` parameter. - `total_results` (integer, optional) — The total number of results from all pages. - `total_pages` (integer, optional) — **Offset pagination only**: The total number of pages. Only present when using the deprecated `page` parameter. ## Errors ### 400 Bad Request Error Bad Request - `status` (integer, required) - `statusText` (string, required) - `errors` (list of ErrorDetail, required) ### 401 Unauthorized Error Unauthorized. The API key or OAuth access token is missing, invalid, or expired. - `status` (integer, required) - `statusText` (string, required) - `errors` (list of ErrorDetail, required) ### 403 Forbidden Error Forbidden - `status` (integer, required) - `statusText` (string, required) - `errors` (list of ErrorDetail, required) ### 404 Not Found Error Resource Not Found - `status` (integer, required) - `statusText` (string, required) - `errors` (list of ErrorDetail, required) ### 429 Too Many Requests Error Rate Limit Exceeded - `status` (integer, required) - `statusText` (string, required) - `errors` (list of ErrorDetail, required) ### 500 Internal Server Error Internal Server Error - `status` (integer, required) - `statusText` (string, required) - `errors` (list of ErrorDetail, required) ## Types ### PublicationField - `id` (string, required) — The prefixed ID of the publication field. - `name` (string, required) — The merge tag key for the field. This is what content references, and it is unique within the workspace. - `display` (string, required) — The human readable label for the field. - `kind` (enum, required) — The type of value the field holds. - Allowed values: `text`, `number`, `boolean`, `date`, `color`, `url`, `image_url`, `rss_feed_url`, `json` - `value_source` (enum, required) — Where the value for each publication comes from. - Allowed values: `static`, `fetched` - `response_keys` (list of PublicationFieldResponseKey, required) — The keys declared within the fetched JSON response body. Empty unless `kind` is `json`. - `status` (enum, required) — Whether the field is currently active or has been archived. - Allowed values: `active`, `archived` - `created` (integer, required) — The time the field was created. Measured in seconds since the Unix epoch. - `updated` (integer, required) — The time the field was last updated. Measured in seconds since the Unix epoch. - `default_value` (string, optional) — The value used for publications that have not set one of their own. Null when the field has none configured; `json` and `rss_feed_url` fields are the only kinds not required to have one. - `endpoint_url` (string, optional) — The URL the value is retrieved from. Present only when `value_source` is `fetched`, and may contain merge tags that resolve per publication. ### ErrorDetail - `message` (string, required) - `code` (string, required) ### PublicationFieldResponseKey - `key` (string, required) — The name of the key within the JSON response body. - `kind` (enum, required) — The type of value the key holds. - Allowed values: `text`, `number`, `date`, `url`, `image_url` ## Examples **Response** ```json { "data": [ { "id": "pub_field_00000000-0000-0000-0000-000000000000", "name": "support_email", "display": "Support email", "kind": "text", "value_source": "static", "response_keys": [], "status": "active", "created": 1700000000, "updated": 1700000000, "default_value": "support@beehiiv.com", "endpoint_url": null }, { "id": "pub_field_11111111-1111-1111-1111-111111111111", "name": "weather", "display": "Local weather", "kind": "json", "value_source": "fetched", "response_keys": [ { "key": "temperature", "kind": "text" }, { "key": "icon", "kind": "image_url" } ], "status": "active", "created": 1700000001, "updated": 1700000001, "default_value": null, "endpoint_url": "https://api.example.com/weather" } ], "limit": 10, "has_more": false, "next_cursor": null } ``` **SDK Code** ```python Default import requests url = "https://api.beehiiv.com/v2/workspaces/publication_fields" querystring = {"limit":"10"} headers = {"Authorization": "Bearer "} response = requests.get(url, headers=headers, params=querystring) print(response.json()) ``` ```javascript Default const url = 'https://api.beehiiv.com/v2/workspaces/publication_fields?limit=10'; const options = {method: 'GET', headers: {Authorization: 'Bearer '}}; try { const response = await fetch(url, options); const data = await response.json(); console.log(data); } catch (error) { console.error(error); } ``` ```go Default package main import ( "fmt" "net/http" "io" ) func main() { url := "https://api.beehiiv.com/v2/workspaces/publication_fields?limit=10" req, _ := http.NewRequest("GET", url, nil) req.Header.Add("Authorization", "Bearer ") res, _ := http.DefaultClient.Do(req) defer res.Body.Close() body, _ := io.ReadAll(res.Body) fmt.Println(res) fmt.Println(string(body)) } ``` ```ruby Default require 'uri' require 'net/http' url = URI("https://api.beehiiv.com/v2/workspaces/publication_fields?limit=10") http = Net::HTTP.new(url.host, url.port) http.use_ssl = true request = Net::HTTP::Get.new(url) request["Authorization"] = 'Bearer ' response = http.request(request) puts response.read_body ``` ```java Default import com.mashape.unirest.http.HttpResponse; import com.mashape.unirest.http.Unirest; HttpResponse response = Unirest.get("https://api.beehiiv.com/v2/workspaces/publication_fields?limit=10") .header("Authorization", "Bearer ") .asString(); ``` ```php Default request('GET', 'https://api.beehiiv.com/v2/workspaces/publication_fields?limit=10', [ 'headers' => [ 'Authorization' => 'Bearer ', ], ]); echo $response->getBody(); ``` ```csharp Default using RestSharp; var client = new RestClient("https://api.beehiiv.com/v2/workspaces/publication_fields?limit=10"); var request = new RestRequest(Method.GET); request.AddHeader("Authorization", "Bearer "); IRestResponse response = client.Execute(request); ``` ```swift Default import Foundation let headers = ["Authorization": "Bearer "] let request = NSMutableURLRequest(url: NSURL(string: "https://api.beehiiv.com/v2/workspaces/publication_fields?limit=10")! as URL, cachePolicy: .useProtocolCachePolicy, timeoutInterval: 10.0) request.httpMethod = "GET" request.allHTTPHeaderFields = headers let session = URLSession.shared let dataTask = session.dataTask(with: request as URLRequest, completionHandler: { (data, response, error) -> Void in if (error != nil) { print(error as Any) } else { let httpResponse = response as?
