Clash Subscription Link Import Guide: One-Click Setup & Format Differences Explained

What is a subscription link, and why not enter nodes one by one

The first thing that trips up new Clash users is figuring out where all those rules, proxy groups, and node entries in a config file actually come from. The short answer: in almost every case, you don't need to type in any node details by hand — you just need a subscription URL, and pasting it into the client does the rest. A subscription URL is essentially an address that can be fetched over HTTP; behind it, the provider serves a live-generated config file or node list, and the client periodically requests that address to pull the latest content.

The real value of this mechanism is automatic updating. Node IPs, ports, and expiration dates shift as providers adjust their infrastructure — with a static, manually entered config, you'd have to redo everything once it goes stale. A subscription link, on the other hand, lets the client re-fetch on a schedule, so as long as the subscription itself is still active, node changes sync automatically without you lifting a finger. That's why almost every proxy provider hands out subscription links instead of pre-packaged config files.

Three things to check before grabbing your subscription URL

Before you dive into importing, checking these three points upfront saves most of the troubleshooting later:

1. Link integrity: Subscription URLs tend to be long and start with http:// or https://, so it's easy to drop a character at the start or end when copying by hand. Select the whole string and copy it as one block rather than retyping it.
2. Extra required parameters: Some subscription URLs only return valid content when a specific User-Agent header is sent. If the client's default UA isn't recognized by the provider, the fetch may fail or return an empty config — providers usually flag this requirement in their setup notes.
3. Data allowance and expiry date: A subscription URL doesn't guarantee the nodes behind it are usable forever. Most services have a data cap and an expiration date, so if the import succeeds but nothing connects, checking this first is faster than digging through client settings.

The complete one-click import steps

Interface details vary slightly between clients, but the core steps for importing a subscription are consistent across the board — roughly four steps:

1. Copy the subscription link: Copy the full subscription URL from the provider's page or email to your system clipboard.
2. Open the subscription management screen in the client: Usually labeled "Profiles," "Subscriptions," or similar, with a "New," "Import," or "+" button somewhere on screen.
3. Paste the link and save: Most clients let you paste the URL directly and confirm, triggering an automatic fetch of the remote config; some also let you assign a custom name to tell multiple subscriptions apart.
4. Wait for the fetch to finish, then select it: Once the fetch succeeds, proxy groups and rule sets will show up in the profile list. Set this subscription as the active profile, then head to the proxy tab to pick a node or group strategy and you're good to go.

If the client supports "scan to import," you can turn the subscription link into a QR code and scan it with your phone's camera to do the same thing — common when jumping from a web page into a mobile client.

Common reasons pasting fails

• The link contains a stray space or line break — check it in a plain text editor before pasting and strip any extra characters.
• Your network can't reach the subscription server's domain at all. In this case, connect through a working node or proxy first, then switch to the real subscription.
• The client can't parse the format the subscription returns — usually a cross-version compatibility issue, covered in the format differences section below.

Setting up auto-updates to keep nodes from going stale

A successful import is only step one — most of a subscription's value comes from auto-updating. In the subscription's detail or edit screen, you'll typically find an "Update Interval" setting, usually measured in hours. Recommended settings:

• For everyday use, a 12–24 hour update interval works well — frequent enough to catch node changes promptly, without hammering the subscription server with requests.
• Some providers rate-limit how often a subscription URL can be requested. Refreshing manually too often may trigger a temporary limit — if nodes disappear right after a refresh, wait a bit before trying again.
• If the client has an "auto-update on launch" toggle, turn it on — this way, every time you restart the client it tries to fetch the latest config, cutting down on nodes going stale from long periods without an update.

You can also trigger an update manually — most clients show a refresh icon or "Update" button next to each subscription in the list. Tapping it immediately re-requests the subscription URL and overwrites the locally cached config.

Native Clash subscriptions vs. generic share links: format differences

This is where beginners get tripped up most often: not all "subscription links" floating around are the same format. They fall roughly into two categories, and which one you have directly determines whether Clash-based clients can read it out of the box.

Native Clash subscription format

This type of subscription URL returns content that's already a valid Clash config YAML file, typically with top-level fields like proxies, proxy-groups, and rules. A rough structure looks like this:

proxies:
  - name: "Example Node"
    type: ss
    server: example.com
    port: 443
    cipher: aes-256-gcm
    password: "xxxx"

proxy-groups:
  - name: "Auto Select"
    type: url-test
    proxies:
      - Example Node

rules:
  - DOMAIN-SUFFIX,example.com,Auto Select
  - MATCH,DIRECT

The upside of this format is that it works right out of the box — the client fetches it and needs zero conversion; the rules and group strategies are already pre-built by the provider, so you don't need to know YAML syntax at all. The vast majority of services built specifically for Clash / Clash Meta (mihomo core) hand out this exact format.

Generic share link format (vmess://, ss://, etc.)

The other common type, seen mostly in other proxy tool ecosystems, starts with a protocol prefix like vmess://, ss://, or trojan://. It's essentially node parameters packed into a Base64-encoded string, e.g. vmess://eyJ2IjoiMiIsInBzIjoi.... This format was originally designed for single-node sharing with lightweight clients and contains none of Clash's proxy-group or rule structures — strictly speaking, it's not a "Clash subscription" at all, but a "node share code."

Pasting this kind of link directly into an input field that only accepts native Clash YAML will almost always fail or throw a parse error — this is one of the most common reasons users report that "the subscription won't import."

Bridging the two: how subscription conversion works

The standard workaround is a "subscription converter" service that batch-converts vmess://, ss://, and similar share codes or aggregated lists into Clash-readable YAML, then generates a new converted subscription URL for the client to use. The conversion process usually involves:

1. Submitting the original share link (or an aggregated address containing multiple share links) to the converter service;
2. The converter decodes each link's node parameters and rebuilds them into a proxies field following Clash config syntax;
3. Combining that with a preset or custom rule template to generate a complete proxy-groups and rules section;
4. Outputting a new subscription URL — this one returns standard Clash YAML, and can be added to the client using the one-click import steps above.

Keep in mind that a converter service sits between the original link and the final config as a middleman. If the original node data contains sensitive parameters, pick a converter carefully — stick to ones with a clear source and verifiable reputation, and check whether the converted subscription URL itself also has an expiry date or data cap.

Extra subscription fields supported by Clash Meta (mihomo core)

If your client runs on Clash Meta (the mihomo core), the subscription YAML may include extension fields beyond standard Clash — node parameters for protocols like Hysteria and TUIC, or remote rule-set references via rule-providers. These are capabilities added at the core level, so if the client is running an older core version, unrecognized protocol types or fields may simply be skipped during import rather than causing the whole import to fail. If you notice "the subscription imported fine, but there are fewer nodes than expected," check whether the client's core version actually supports the protocol types in use.

Quick FAQ

The subscription imported but there are no nodes, just a DIRECT entry?

This usually means the subscription URL returned empty content or an error page instead of an actual config file. Try opening that URL directly in a browser to see what it returns — check for messages about exhausted data or an expired subscription.

Can I import multiple subscriptions at once?

Yes. Most clients let you add several subscriptions and switch which one is active from a list, and some can even merge nodes from multiple subscriptions into one view — it depends on how the client's subscription management is designed.

How often do I need to replace a subscription link?

As long as the provider hasn't rotated the subscription URL and your account is still valid, the same link can be reused indefinitely — the client will keep pulling the latest nodes at your set update interval, with no need to swap out the link itself.
