Notis

Keep monitoring aligned with updated transaction docs

When a transaction document changes, Notis can check its current contents and prepare a Blocknative subscription for the hash it contains.

Trigger

File Updated

Triggers when a file's metadata or content changes in Google Drive.

Action

Subscribe Transaction Hash

Tool to subscribe to transaction state change events of an ethereum transaction hash. use after establishing a blocknative websocket connection to prepare the subscription message.

Why this helps

Updated transaction notes can introduce a hash that never makes it into the monitoring workflow.

  • Use document updates as a reminder to start monitoring.
  • Keep the source of transaction details in Drive.
  • Have Notis report when the updated file lacks a usable hash.

Setup

Build it in a few focused steps.

  • 1Connect Google Drive and Blocknative once in the Notis portal.
  • 2Create an automation in the portal or tell Notis in plain language what to do.
  • 3Ask Notis in one instruction to check updated Drive files for an Ethereum transaction hash and prepare a Blocknative subscription when one is present.
  • 4Choose the File Updated trigger and a report channel, then test with one real updated transaction document.

Questions about this workflow

Will this cancel an earlier subscription if the hash changes?

No. The listed action prepares a subscription for a transaction hash; it does not unsubscribe from a prior hash. Handle any cleanup separately.

Can it detect changes in the file's contents?

The trigger fires when Drive file metadata or content changes. Notis can inspect the returned file details available to it.

Supported Triggers and Actions

Notis builds workflows that link Google Drive to Blocknative. A trigger fires from one place; an action lands in another.

Google Drive triggers

Blocknative actions

Recurring trigger

Notis starts this workflow on a schedule, such as daily, weekly, or during business hours.

TriggerScheduled

Configure Mempool Filters

Tool to configure filters and abi decoding for ethereum mempool transactions. use after establishing a blocknative websocket connection to set up event filters and decoding.

ActionInstant

Webhook trigger

Notis starts this workflow when an external tool or custom backend sends an HTTP request.

TriggerInstant

Get Gas Price Distribution

Tool to retrieve the current mempool gas price distribution breakdown. use when analyzing gas price trends or preparing fee strategies.

ActionInstant

Comment Added (Docs/Sheets/Slides)

Triggers when a new comment is added to Google Docs, Sheets, or Slides.

TriggerPolling

Get Gas Oracles

Tool to retrieve metadata on supported gas oracles per chain. use when you need to dynamically discover all available on-chain gas estimation oracles across networks.

ActionInstant

File Created

Triggers when a new file is created in Google Drive.

TriggerPolling

Get Gas Prices

Tool to fetch gas price estimates for specific inclusion probabilities. use when you need gas price ranges for the next block or next ~10 seconds.

ActionInstant

File Deleted or Trashed

Triggers when a file is moved to trash or permanently deleted in Drive.

TriggerPolling

Get Supported Chains

Tool to retrieve supported chains metadata. use when discovering available networks for blocknative gas services.

ActionInstant

File Shared (Permissions Added)

Triggers when new sharing permissions are granted to a file or folder. Uses Drive's `changes.list` endpoint with inline `permissions` in the `fields` mask so each change carries the file's current permission set provider-atomically. We diff that against `seen_permission_keys` to identify newly added grants. Drive page tokens are the primary cursor; if Drive rejects a stored token, the trigger raises `PollingTriggerError` without clearing state rather than silently re-baselining and dropping events. Limitation: truly ephemeral permissions (added and revoked between two polls without any other file modification in between) are not detected. Drive Activity API would catch those but requires an additional OAuth scope and a different payload contract.

TriggerPolling

Get Base Fee Estimates

Tool to get real-time predictions for base fee and blob base fee for the next 5 blocks. use when you need both 99% and 50% confidence estimates for upcoming blocks.

ActionInstant

File Updated
