Example Use Cases
These are example ways Snow can use Kit when building apps with you. This list is meant to show examples, not document every possible capability. Connecting an account does not make Snow run these automatically on its own.
Add an existing subscriber to a form by their IDs. This action associates a subscriber with a form in Kit. The subscriber must already exist in your Kit account (use KIT_LIST_SUBSCRIBERS to find them). The form must also exist (use KIT_LIST_FORMS to find valid form IDs). Returns HTTP 201 if the subscriber is newly added to the form, or HTTP 200 if they were already associated with the form. Both cases are considered successful operations. Important: This action requires both form_id and subscriber_id (aliased as 'id' in requests). An optional referrer URL can be provided for tracking purposes and will have its UTM parameters automatically parsed.
Tool to add an existing subscriber to a form using their email address. Use when you know the subscriber's email but not their ID. The subscriber must already exist in your Kit account before adding them to a form. Returns HTTP 201 if the subscriber is newly added to the form, or HTTP 200 if they were already associated with the form.
Tool to create a new broadcast (email campaign) to send to subscribers. Use when you need to draft, schedule, or immediately publish an email broadcast. To save as draft, set send_at to null; to schedule, provide a future send_at timestamp; to publish to web, set public to true.
Tool to create a new custom field for subscriber data. Use when you need to store extra attributes for subscribers.
Tool to create a new subscriber or update an existing one (upsert). If a subscriber with the provided email address does not exist, creates one. If already exists, updates the first name.
Tool to create a new tag in the account. Use when you need a custom label to segment subscribers. Use after confirming tag uniqueness to avoid duplicates. Example: "Create a tag called 'VIP' for premium customers."
Creates a webhook subscription for real-time event notifications. Use this to receive HTTP POST notifications when subscriber events (activate, unsubscribe, form subscribe, tag add/remove, link clicks, etc.) or purchase events occur in your Kit account.
Tool to delete a specific broadcast. Use when you need to permanently remove a broadcast by ID (after confirming the ID). Example prompt: "Delete broadcast with ID 123"
Tool to delete a specific custom field. Use after confirming the custom field ID is correct. Deletes the field permanently.
Unsubscribe a subscriber from all email communications by their ID. This action permanently unsubscribes a subscriber, removing them from all sequences and forms. The subscriber's historical data is retained but they will no longer receive emails. This operation is idempotent - unsubscribing an already-unsubscribed subscriber succeeds without error. Use KIT_LIST_SUBSCRIBERS to find valid subscriber IDs before calling this action. Returns: Empty response on success (HTTP 204 No Content). Raises: ExecutionFailed: If the subscriber ID doesn't exist (404), authentication fails (401), or other API errors occur.
