How to Auto-Post an RSS Feed to DingTalk Groups (2026)

Updated: 2026-09-28

Short answer: add a custom robot to the DingTalk group you want posts in, set its security mode to signature, and copy both the webhook address and the signing secret. In PostRSS open Accounts → Add new DingTalk account, paste both, then open Célplatformok → Add feed, choose DingTalk in Target settings and add your feed under Add source (Type = RSS feed, Link = your feed address). Each new item lands in the group as a card with its title, summary, image and link. No developer registration is needed. DingTalk is included from the Professional plan ($10/month).

DingTalk — DingDing to its users — is Alibaba's workplace platform, and in a great many Chinese companies it is simply where work happens: chat, attendance, approvals and internal announcements. If your colleagues, distributors or customers in China are on it, a group robot is the shortest path from your website to their screens.

Why a group robot is the easy path

Most publishing integrations require registering a developer account, creating an application, requesting scopes and waiting for approval. A DingTalk custom robot requires none of that. It is added from inside a group by someone who can administer it, it lives only in that group, and it is addressed by one webhook URL. There is no marketplace listing, no company verification step and no Chinese business licence involved.

Creating the robot, step by step

1. Open the DingTalk group you want the posts in, on desktop for preference — the robot settings are easier to reach there.
2. Open group settings and find the group assistant (robot) section.
3. Add a robot and choose the custom type, the one described as connecting through a webhook.
4. Name it something the group will recognise, and accept the terms DingTalk shows.
5. Choose "signature" as the security setting. DingTalk requires you to pick at least one of three; this is the one to use. Copy the secret it generates — it begins with SEC.
6. Copy the webhook URL. It looks like https://oapi.dingtalk.com/robot/send?access_token=…. Anyone holding it can post into the group, so treat it as a credential.
7. In PostRSS, open Accounts → Add new DingTalk account and paste the webhook address and the signing secret.
8. Open Targets → Add feed, choose DingTalk in Target settings, then Add source with Type = RSS feed and your feed address in Link. Save.

Why signature and not custom keywords

DingTalk makes you choose a security mode: custom keywords, an IP allowlist, or a signature. Keywords are the default people reach for and the one that quietly breaks a feed. The rule is that a message is only accepted if its text contains one of the keywords you configured — so the first article whose title does not happen to contain your keyword is rejected, and nothing tells you it happened. You discover it weeks later when someone asks why a post never appeared.

An IP allowlist has a different failure mode: it depends on the sending addresses staying fixed, and it breaks silently when they do not. A signature avoids both. Each request carries a timestamp and a hash built from the secret, DingTalk verifies it, and what the message says has no bearing on whether it is delivered.

What the group sees

Each new feed item arrives as a card: the article title as the headline, a short summary underneath, the image from the feed item, and a link through to the original. It reads like a proper share rather than a pasted URL, which matters in a channel where colleagues skim.

If a feed item has no image, the card is rendered without one rather than failing. Nothing can invent a picture that is not in the feed, so if images matter, check that your CMS actually puts one in the feed before blaming the integration.

Rate limits

DingTalk limits a custom robot to 20 messages per minute. Exceed it and the robot is throttled for a period rather than permanently blocked. For an RSS feed this ceiling is far away: PostRSS checks each feed every 5 minutes and sends one message per new item, so you would need twenty new articles inside the same minute to reach it. The situation where it does matter is pointing several high-volume feeds at one group, or importing a backlog — in both cases, split them across separate targets.

When messages stop arriving

• Signature errors. Re-copy the SEC secret carefully; a trailing space is the usual culprit. Regenerating the robot changes both the webhook and the secret.
• Keyword security still enabled. Switch the robot to signature; keyword filtering drops anything that does not match.
• The robot was removed. Any group administrator can delete it, and delivery stops with no notification to you.
• You hit the rate limit. Throttling is temporary; spread high-volume feeds across targets to avoid repeating it.
• No new feed items. PostRSS posts items that appear after the Target starts running, so an unchanged feed produces nothing — that is correct behaviour, not a fault.

Group chats are not public feeds

This is the one thing worth being clear about before you set anything up. A group bot posts into a conversation — a team channel, a customer group, a community room. It does not publish to a public timeline, nobody outside the group sees it, and there is no follower count attached to it. That makes it excellent for internal distribution, release notes, support announcements and community updates, and useless as a marketing channel on its own.

If what you actually want is to publish articles to a Chinese public audience, the destination for that is a WeChat Official Account, which PostRSS supports from Professional Plus at $20/month for approved accounts. And to answer the question that always follows: Bilibili is not supported, and not because of a missing integration — its publishing API requires a Chinese legal entity, which puts it out of reach for a company registered elsewhere.

Which plan includes it

It is part of the Professional plan at $10/month, the same tier as Discord, Pinterest boards, VKontakte, Tumblr, Nostr, WordPress and Blogger. Feishu / Lark, DingTalk and WeCom all sit there together, so one subscription covers all three if your organisation uses more than one. Professional allows 10 targets and 10,000 posts a month; each group you post into is one target. An annual subscription is 20% cheaper. Exact limits per tier are on the pricing page, and the full lineup of 26 networks is on the supported networks page.

Frequently Asked Questions

Do I need a DingTalk developer account or a Chinese company to set this up?

No. A custom group robot is created from inside the group and needs no developer registration, no application review and no Chinese legal entity. You need permission to manage the group, and that is all.

Why does PostRSS ask for a signing secret?

DingTalk requires one of three security modes on a custom robot, and the signature is the only one that works dependably for a feed. Custom keywords reject any message whose text lacks the keyword, which for article titles means posts disappearing without warning.

Does the post include the article image?

Yes, when the feed item has one. DingTalk items are delivered as a card with title, summary, image and link. If the feed carries no image, the card is rendered without it.

What is DingTalk’s rate limit?

Twenty messages per minute per robot. An RSS feed checked every 5 minutes does not come close unless you are running several high-volume feeds into one group, in which case split them across separate targets.

Can one feed go to several DingTalk groups?

Yes. Each group is a separate Target with its own robot and webhook, and the same feed can be added as a source on all of them. Professional allows 10 targets.

Is a DingTalk group a public channel?

No. It is a conversation, visible only to its members. For a public Chinese audience, a WeChat Official Account is the right destination; Bilibili is not supported at all, because its publishing API requires a Chinese legal entity.

The bottom line

DingTalk is one of the quickest destinations to connect, because a group robot needs no developer account and no approval. Add the robot, choose the signature security mode, paste the webhook and the secret into PostRSS, and every new article arrives in the group as a card your colleagues can act on. It is on the Professional plan at $10/month, alongside Feishu / Lark and WeCom.
