comments.create
Publish a comment on a post.
Prerequisites
- A Curviate API key, passed as
apiKeywhen you construct the client. Authentication and accounts shows how to create one. - A connected LinkedIn account. This resource is account-scoped: the
account_idis injected automatically by the account-scoped accessor, so you pass it once tocurviate.account(...)and every call below inherits it. Authentication and accounts covers connecting one, and accounts.list returns theaccount_idof each account already connected.
Signature
create(postId: string, body: CreateCommentBody): Promise<CreateCommentResult>Example
import { Curviate } from "@curviate/sdk";
const curviate = new Curviate({
apiKey: "cvt_live_...",
baseUrl: "https://api.curviate.com",
});
const result = await curviate.account("acc_YOUR_ACCOUNT_ID").comments.create("urn:li:activity:YOUR_POST_ID", { text: "Great write-up, the section on tool design matched our experience exactly." });
console.log(result.id);Parameters
| Name | Type | Required | Description |
|---|---|---|---|
postId | string | Yes | The post's id exactly as returned by get-post / list-posts (the opaque id form). Other id forms (bare numeric, urn:li:..., share URLs) are not accepted on this operation; fetch the post first and use its id verbatim. |
text | string | Yes | Comment body text (1-1250 chars). Inline @mentions live in the text (e.g. "@ACoAA..."). Not stored or logged. |
comment_as | string | No | Publish as another user or company page id, the account must administer it. |
attachments | array | No | At most one base64 image attachment (LinkedIn's one-image-per-comment limit). Platform rendering of comment attachments is not guaranteed. |
Returns
Resolves to CreateCommentResult. Top-level fields: object, id, created_at, text, reply_count, reactions, reaction_count, author, can_reply, can_react, is_sender, attachments.
Error codes
| Code | What it means, and what to do |
|---|---|
UNAUTHORIZED | The API key is missing, malformed, or revoked. Check the key you passed to the client. |
INVALID_REQUEST | A parameter failed validation. The message names the offending field; fix the request rather than retrying it. |
RATE_LIMIT_ACCOUNT | This account's own quota is exhausted. Wait for the window in the Retry-After header, then retry. |
RATE_LIMIT_TENANT | The tenant-wide quota is exhausted across all accounts. Slow the whole workload, not just this call. |
PLATFORM_RATE_LIMIT | LinkedIn is throttling this account. Back off well beyond the hinted delay; sustained pressure risks the account. |
PLATFORM_ERROR | A transient upstream failure. Retry once with backoff before treating it as a real error. |
ACCOUNT_NOT_FOUND | No connected account with that id belongs to this tenant. List your accounts to get a current id. |
PAYLOAD_TOO_LARGE | The body exceeds the size cap. Base64 encoding inflates a file by about a third, so budget for that. |
RESOURCE_NOT_FOUND | The id in the path does not exist, or is not visible to this account. Re-read it from the list endpoint that produced it. |
UNSUPPORTED_MEDIA_TYPE | The request was not sent as JSON. Every endpoint takes application/json, including file attachments, which travel base64-encoded. |
Every code above is a stable CurviateError.code you can branch on. The full list, the response envelope, and retry semantics are in the Error codes reference.
