Connect

Read a Facebook Page's webhook subscription

Returns the webhook fields Zernio's app is subscribed to on the connected Page, read live from Meta. Use it to confirm leadgen is present: a Page missing it keeps delivering every other event while lead ads stop arriving, with nothing to indicate it.

Connect a Shopify store with a custom-app Admin token

Token-paste alternative to the OAuth flow: connect a store using the Admin API access token of a custom app the merchant created in their own Shopify admin (Settings → Apps and sales channels → Develop apps, with the `read_content`/`write_content` scopes). Use this when the one-click OAuth connect is unavailable or when your users prefer not to install a third-party app on their store. The token is validated against the store before anything is saved; custom-app tokens do not expire. Connecting the same profile to a store again replaces the stored token in place.

Re-subscribe a Facebook Page to Zernio's webhooks

Re-sends the full field set to Meta and returns the subscription read back afterwards. Meta only honours the field set sent at subscribe time, so a Page connected before a field existed stays without it until this runs. The response reflects what Meta actually granted, not what was requested.
