Provide the unified PlmBomline fields to change in the request body. ## Parameters **fields**string array id created\_at updated\_at parent\_part\_id child\_part\_id child\_revision quantity unit\_of\_measure line\_number reference\_designators effective\_at expires\_at notes raw Fields to return **raw**string Raw parameters to include in the 3rd-party request. Encoded as a URL component. eg. raw parameters: foo=bar&zoo=bar -> raw=foo%3Dbar%26zoo%3Dbar **connection\_id**string required ID of the connection **id**string required ID of the Bomline ## Payload One parent to child usage in a bill of materials **id**string **created\_at**date-time (ISO-8601 / YYYY-MM-DDTHH:MM:SSZ format) **updated\_at**date-time (ISO-8601 / YYYY-MM-DDTHH:MM:SSZ format) **parent\_part\_id**string The assembly **child\_part\_id**string The component's PlmPart ID (a revision ID) **child\_revision**string Pinned child revision, when the line pins one **quantity**number **unit\_of\_measure**string **line\_number**string Find or item number on the BOM **reference\_designators**string array **effective\_at**date-time (ISO-8601 / YYYY-MM-DDTHH:MM:SSZ format) **expires\_at**date-time (ISO-8601 / YYYY-MM-DDTHH:MM:SSZ format) **notes**string **raw** Raw data from integration ## Returns [PlmBomline](https://docs.unified.to/plm/bomline/model.md) | Response field | Type | Required | Description | | ---------------------- | ------------------ | -------- | --------------------------------------------- | | id | string | No | | | created\_at | string (date-time) | No | (ISO-8601 / YYYY-MM-DDTHH:MM:SSZ format) | | updated\_at | string (date-time) | No | (ISO-8601 / YYYY-MM-DDTHH:MM:SSZ format) | | parent\_part\_id | string | No | The assembly | | child\_part\_id | string | No | The component's PlmPart ID (a revision ID) | | child\_revision | string | No | Pinned child revision, when the line pins one | | quantity | number | No | | | unit\_of\_measure | string | No | | | line\_number | string | No | Find or item number on the BOM | | reference\_designators | string\[\] | No | | | effective\_at | string (date-time) | No | (ISO-8601 / YYYY-MM-DDTHH:MM:SSZ format) | | expires\_at | string (date-time) | No | (ISO-8601 / YYYY-MM-DDTHH:MM:SSZ format) | | notes | string | No | | ## Errors Errors return the HTTP status code and a JSON body with `statusCode`, `error` (the short label) and `message` (a human-readable detail). ```json { "statusCode": 429, "error": "Too Many Requests", "message": "Too many requests to unified.to API; max requests per minute: N" } ``` | Status | Error | Meaning | | ------ | --------------------- | ------------------------------------------------- | | 400 | Bad Request | The request was malformed or failed validation. | | 401 | Unauthorized | The connection is likely broken; re-authorize it. | | 403 | Forbidden | The connection is missing permissions or scopes. | | 404 | Not Found | The requested resource does not exist. | | 429 | Too Many Requests | Rate limit exceeded (see the two sources below). | | 500 | Internal Server Error | An unexpected error occurred. | | 501 | Not Implemented | Not supported by this integration. | Errors from the underlying integration pass through: the integration's status comes back as ours (429, 401, 403, 404 or 5xx), usually with its message. When the integration's error body is unclear, Unified extracts what it can and returns a clearer message. ### 429 Too Many Requests A 429 has two possible sources: * The integration's own rate limit, passed through. * Unified's workspace limit: a rolling 60 seconds, set by plan, with the message `Too many requests to unified.to API; max requests per minute: N`. ## Code Samples ### Node.js SDK ```javascript import { UnifiedTo } from '@unified-api/typescript-sdk'; const sdk = new UnifiedTo({ security: { jwt: '', }, }); const connectionId = '5de520f96e439b002043d8dc'; const id = '1234'; const results = await sdk.plm.updatePlmBomline({ connectionId, id, plmBomline: { }, fields: '', raw: '', }); ``` ### Node.js (axios) ```javascript const options = { method: 'PUT', url: 'https://api.unified.to/plm/5de520f96e439b002043d8dc/bomline/5de520f96e439b002043d8d8', headers: { authorization: 'bearer .....' }, data: undefined, params: { fields: '', raw: '', } }; const results = await axios.request(options); ``` ### Java ```java AsyncHttpClient client = new DefaultAsyncHttpClient(); client.prepare("PUT", "https://api.unified.to/plm/5de520f96e439b002043d8dc/bomline/5de520f96e439b002043d8d8?fields=&raw=") .setHeader("accept", "application/json") .setHeader("authorization", ".....") .execute() .toCompletableFuture() .thenAccept(System.out::println) .join(); client.close(); ``` ### Go ```go import ( "fmt" "net/http" "io/ioutil" ) url := `https://api.unified.to/plm/5de520f96e439b002043d8dc/bomline/5de520f96e439b002043d8d8?fields=&raw= req, _ := http.NewRequest("PUT", url, nil) req.Header.Add("accept", "application/json") req.Header.Add("authorization", ".....") res, _ := http.DefaultClient.Do(req) defer res.Body.Close() body, _ := ioutil.ReadAll(res.Body) ``` ### Python ```python import requests url = "https://api.unified.to/plm/5de520f96e439b002043d8dc/bomline/5de520f96e439b002043d8d8?fields=&raw=" headers = { "accept": "application/json", "authorization": "....." } response = requests.put(url, headers=headers) ``` ### PHP ```php $curl = curl_init(); curl_setopt_array($curl, [ CURLOPT_URL => "https://api.unified.to/plm/5de520f96e439b002043d8dc/bomline/5de520f96e439b002043d8d8?fields=&raw=", CURLOPT_RETURNTRANSFER => true, CURLOPT_ENCODING => "", CURLOPT_MAXREDIRS => 10, CURLOPT_TIMEOUT => 30, CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1, CURLOPT_CUSTOMREQUEST => "PUT", CURLOPT_HTTPHEADER => [ "accept: application/json", "authorization: ....." ], ]); ``` ### Ruby ```ruby require 'uri' require 'net/http' require 'openssl' url = URI("https://api.unified.to/plm/5de520f96e439b002043d8dc/bomline/5de520f96e439b002043d8d8?fields=&raw=") http = Net::HTTP.new(url.host, url.port) http.use_ssl = true request = Net::HTTP::Put.new(url) request["accept"] = 'application/json' request["authorization"] = '....' response = http.request(request) puts response.read_body ``` ### cURL ```bash curl --request PUT \ --url 'https://api.unified.to/plm/5de520f96e439b002043d8dc/bomline/5de520f96e439b002043d8d8?fields=&raw=' \ --header 'accept: application/json' \ --header 'authorization: .....' ```
