A follow gate only enforces anything if the product can check the follow. Many tools that use the label ask the visitor to tap “I followed” and then hand over the link. That is a confirmation step, not verification. A tool that revokes access automatically needs two more things: a platform signal that the qualifying state has changed, and a way to apply that change to the access it granted. Whether either is possible depends on the platform and on which API permissions the app has been granted.
This guide explains the difference between a self-reported follow gate and a checked one, shows how membership and authorization events can drive access decisions, and marks where platform rules limit what you can promise users.
What a follow gate actually promises
A follow gate makes a link or other benefit conditional on following an account. The word “gate” covers at least two different designs, and they should not be sold as equivalent.

CreatorFlow’s help documentation describes an Instagram follow gate that asks the person to follow and then confirm. The vendor states that the flow “runs on an honor system” and that “CreatorFlow cannot verify whether someone followed your account.” A person who confirms without following still receives the link. The same page warns that non-followers may not see message requests and that the extra step can reduce completion. It gives no quantified rate for that drop-off, so treat the friction as a qualitative trade-off rather than a measured cost. Source: CreatorFlow follow gate documentation.

The checked gate
Dartzo’s documentation describes a separate Access gate that checks with Instagram whether the person follows the account at the moment they request the link. Its “ask them to follow first” option is unchecked in that setup. This is a different product promise, and it is the vendor’s own description of its behavior, not an independent test of how the platform responds in every case.

The three parts of automatic revocation
Automatic revocation is easiest to reason about when you separate three questions:
Rank #2
- POWERFUL SECURITY KEY: The YubiKey 5C NFC is the most versatile physical passkey, protecting your digital life from phishing attacks. It ensures only you can access your accounts
- WORKS WITH 1000+ ACCOUNTS: Compatible with popular accounts like Google, Microsoft, and Apple. A single YubiKey 5C NFC secures 100+ of your favorite accounts, including email, password managers, and more
- FAST & CONVENIENT LOGIN: Plug in your YubiKey 5C NFC via USB and tap it, or tap it against your phone (NFC), to authenticate. No batteries, no internet connection, and no extra fees required
- MOST SECURE PASSKEY: Supports FIDO2/WebAuthn, FIDO U2F, Yubico OTP, OATH-TOTP/HOTP, Smart card (PIV), and OpenPGP. That means it’s versatile, working almost anywhere you need it
- PRIMARY & SPARE KEYS: Just like having a spare house key, we recommend buying two YubiKeys - one for daily use and one as a spare. That way you’ll never get locked out of your accounts
- The qualifying state. What must be true for access to be allowed? Examples include following an account, holding an active paid membership, or having an authorization granted to your app.
- Change detection. How does your service learn that the state changed? The options are a direct status query, a platform webhook, or a periodic re-check you run yourself.
- Entitlement application. How does a detected change turn into a revoked download, removed role, or closed link? This part is usually your code and your external system, not the platform’s.
Most failures happen at the second step. A webhook can tell you a membership ended, but it cannot tell you that a link you already handed out is no longer being used. Keep those claims apart in your product copy.

Where revocation signals come from
Membership webhooks: Patreon
Patreon’s API reference documents member create, update, and delete events, along with webhook delivery. Webhooks are configured per client, and deliveries are signed with a secret that your endpoint should validate before it acts on a payload. Failed delivery attempts are queued. The reference also says the legacy v1 pledge triggers are being retired and points developers to v2 members:* triggers. Check the current migration notes before building against either version, because the trigger names you code against determine which events you receive. Source: Patreon API Reference.

Authorization revocation: Discord
Discord’s developer documentation describes an APPLICATION_DEAUTHORIZED webhook event. It fires when a user’s authorization for your app is revoked through an unlink, a token revocation, or a Discord account ban. The documentation distinguishes revocations your application starts from those that happen outside it, and the webhook is how you learn about the second kind. This is a platform-specific pattern. It shows that a platform can expose revocation events, not that every platform does. Source: Discord account linking documentation.
Instagram and TikTok: what is not established
The official Instagram API overview surfaced for this topic covers professional-account content management and insights. Nothing in that overview establishes a general endpoint that tells an app whether an arbitrary user follows a given account. Do not design a checked gate around such an endpoint until you have confirmed it in Meta’s current documentation for your account type and permissions. TikTok’s QR authorization documentation covers the status of a user’s authorization, not whether the user follows an account.

Comparing the approaches
| Aspect | Honor-system gate (CreatorFlow) | Checked gate at request time (Dartzo) | Membership webhook (Patreon) | Authorization revocation event (Discord) |
|---|---|---|---|---|
| Verification | None; the visitor’s confirmation is the signal | Platform check with Instagram when the link is requested, per vendor documentation | Platform reports member create, update, and delete events | Platform reports revocation by unlink, token revocation, or account ban |
| Trigger | Visitor confirms after being asked to follow | Visitor requests the link | Membership change | Authorization revoked |
| Change detection | None after the link is delivered | Status checked at each request; no re-check after delivery is documented | Webhook delivery, signed and retried on failure | Webhook event |
| Failure behavior | Not applicable; nothing is checked | Not stated in the vendor documentation reviewed | Failed deliveries are queued; retry timing not stated in the reference reviewed | Not stated in the Discord documentation reviewed |
| User friction | Extra step; vendor warns of lower completion with no quantified rate | Not stated in the vendor documentation reviewed | None added to the user; the member already paid or joined | None added to the user |
| Scope | Instagram follow gate | Instagram follow check, per Dartzo | Patreon memberships; v2 members:* triggers per current docs | Discord applications using authorization |
Failure modes to design for
- Confirmation without follow. With an honor-system gate, this is guaranteed to happen at some rate. Do not describe the gate as enforcement.
- Unobservable unfollows. If you check follow status only at request time, a person who unfollows later keeps any link they already received. Say so in the product’s terms.
- Delayed or missed events. Webhook deliveries can fail and be retried. Your handler must be idempotent, because the same event may arrive more than once.
- Unsigned or forged payloads. Validate the signature for every webhook before changing access.
- Expired or revoked tokens. A failed API call should not be read as “not following.” Treat it as unknown and decide in advance whether to deny, allow, or retry.
- Access already issued outside your system. If a grant lives in an external file host or invite link, your revocation must call that system. Otherwise you have only changed your own database.
A build sequence that respects these limits
- Write down the qualifying state in one sentence, for example “the visitor follows the account at the moment of request” or “the member has an active paid membership.”
- Confirm the platform mechanism for that state in the platform’s current documentation. Record the permission scope, the account type, and the date you checked.
- Choose the change-detection method the platform actually supports: a request-time query, a webhook, or a scheduled re-check. Do not promise a method the API does not expose.
- Build the webhook endpoint or check handler to verify signatures, record each event ID, and process repeats safely.
- Define the fallback for API errors and token failures before launch, and log which path was taken.
- Connect revocation to the external system that holds the access, then test that the revoked item actually stops working.
- Write the user-facing promise to match the mechanism. “Access is checked when you request it” is accurate for a request-time check. “Access ends the moment you unfollow” is not, unless you can observe that event.
Questions to answer before you promise revocation
- Which platform and account type are supported, and which API permissions does the app need?
- Which event or query tells you the qualifying state changed?
- What happens when the API is unavailable, a token is invalid, or an event arrives late?
- Which access grants live outside your system, and how do you revoke them?
- Will non-followers still see the message request or confirmation step, and how many visitors will drop off because of it?
