Triggers and actions 5 triggers · 65 actions
Trigger
Email SentFires when an email is sent from the mailbox (optionally filtered by query).
Trigger
New Gmail MessageFires when a new email arrives (optionally filtered by query/labels).
Action
Add Label To EmailAdds and/or removes specified gmail labels for a message; ensure `message id` and all `label ids` are valid (use 'listlabels' for custom label ids).
Action
Batch Delete MessagesTool to permanently delete multiple Gmail messages in bulk, bypassing Trash with no recovery possible. Use when you need to efficiently remove large numbers of emails (e.g., retention enforcement, mailbox hygiene). Use GMAIL_MOVE_TO_TRASH instead when reversibility may be needed. Always obtain explicit user confirmation and verify a sample of message IDs before executing. High-volume calls may trigger 429 rateLimitExceeded or 403 userRateLimitExceeded errors; apply exponential backoff.
Action
Batch Modify MessagesModify labels on multiple Gmail messages in one efficient API call. Supports up to 1,000 messages per request for bulk operations like archiving, marking as read/unread, or applying custom labels. High-volume calls may return 429 rateLimitExceeded or 403 userRateLimitExceeded; apply exponential backoff.
Action
Create Email DraftCreates a gmail email draft, supporting to/cc/bcc, subject, plain/html body (ensure `is html=true` for html), attachments, and threading.
Action
Create LabelCreates a new label with a unique name in the specified user's gmail account.
Action
Delete DraftPermanently deletes a specific gmail draft using its id; ensure the draft exists and the user has necessary permissions for the given `user id`.
Action
Delete LabelPermanently DELETES a user-created Gmail label from the account (not from a message). WARNING: This action DELETES the label definition itself, removing it from all messages. System labels (INBOX, SENT, UNREAD, etc.) cannot be deleted. To add/remove labels from specific messages, use GMAIL_ADD_LABEL_TO_EMAIL action instead.
Action
Delete MessagePermanently deletes a specific email message by its id from a gmail mailbox; for `user id`, use 'me' for the authenticated user or an email address to which the authenticated user has delegated access.
Action
Delete ThreadTool to immediately and permanently delete a specified thread and all its messages. This operation cannot be undone. Use threads.trash instead for reversible deletion.
Action
Fetch EmailsFetches a list of email messages from a gmail account, supporting filtering, pagination, and optional full content retrieval.
Action
Fetch Message By Message IdFetches a specific email message by its id, provided the `message id` exists and is accessible to the authenticated `user id`.
Action
Fetch Message By Thread IdRetrieves messages from a gmail thread using its `thread id`, where the thread must be accessible by the specified `user id`.
Action
Forward MessageForward an existing Gmail message to specified recipients, preserving original body and attachments. Verify recipients and content before forwarding to avoid unintended exposure. Bulk forwarding may trigger 429/5xx rate limits; keep concurrency to 5–10 and apply backoff. Messages near Gmail's size limits may fail; reconstruct a smaller draft if needed.
Action
Get AttachmentRetrieves a specific attachment by id from a message in a user's gmail mailbox, requiring valid message and attachment ids.
Action
Get ContactsFetches contacts (connections) for the authenticated google account, allowing selection of specific data fields and pagination.

Action
Get FilterTool to retrieve a specific Gmail filter by its ID. Use when you need to inspect the criteria and actions of an existing filter.
Action

Action
Get ProfileRetrieves key gmail profile information (email address, message/thread totals, history id) for a user.
Action
Import MessageTool to import a message into the user's mailbox with standard email delivery scanning and classification. Use when you need to add an existing email to a Gmail account without sending it through SMTP. This method doesn't perform SPF checks, so it might not work for some spam messages.
Action
Insert MessageTool to insert a message into the user's mailbox similar to IMAP APPEND. Use when you need to add an email directly to a mailbox bypassing most scanning and classification. This does not send a message.
Action
List DraftsRetrieves a paginated list of email drafts from a user's gmail account. use verbose=true to get full draft details including subject, body, sender, and timestamp.
Action
List HistoryTool to list Gmail mailbox change history since a known startHistoryId. Use for incremental mailbox syncs.

Action
Settings Send As GetTool to retrieve a specific send-as alias configuration for a Gmail user.

Any of Gmail's 2 triggers in the catalog, including New Gmail Message and Email Sent. Describe the moment in plain language and your agent picks the right one.
What can your agent do in Quaderno when something happens in Gmail?
Any of Quaderno's 24 actions, including Create Contact, Create Estimate, Create Expense and Create Invoice. Your agent maps the data both ways and tests every scenario before it ships.
Can it also run from Quaderno to Gmail?
Yes. When something happens in Quaderno, your agent can act in Gmail too. This page covers both directions: Quaderno's triggers and Gmail's actions are listed here as well.
Do I have to build a connector for Gmail or Quaderno?
No. Both are in the catalog with their triggers and actions. You describe the automation; your agent builds it, tests every scenario and keeps it running.
Can my AI client use Gmail and Quaderno without building an automation?
Yes. With your AI client connected to APIANT, ask it to do something in either app once and it runs that action on the spot. Ask for an automation and your agent builds it, tests every scenario and keeps it running. One connection covers both.
What happens when something fails?
Your agent works that out for you. It plans the failure paths along with the happy path, then tests every scenario before it ships.
Is there a free plan?
Yes. Every plan includes the agent, including free, and building from your own AI client spends no assistant credits.
