Start mempool monitoring from a webhook
Let your internal systems request pending transaction visibility when it matters.
Trigger
Webhook received
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Action
Mempool Subscription
Tool to subscribe to real-time mempool updates for evm chains (ethereum, bnb, etc.). use after constructing your graphql subscription to stream pending transactions live.
Why this helps
Teams miss short-lived pending transaction windows when monitoring is disconnected from internal events.
- Connects internal events to pending transaction data
- Supports fast investigation starts
- Avoids manual subscription setup
Setup
Build it in a few focused steps.
- 1Connect Google Tasks and Bitquery in Notis once.
- 2Create an automation describing the mempool subscription to start.
- 3Pick a webhook as the trigger and share its endpoint with your authorized system.
- 4Choose the report channel and test with one real webhook payload.
Questions about this workflow
Which chains are supported?
Use an EVM network supported by the Bitquery mempool subscription and name it in the webhook payload or instruction.
Does this create a permanent subscription?
The automation follows the subscription behavior supported by the selected Bitquery action; ask for the lifecycle in the run report.

Supported Triggers and Actions
Notis builds workflows that link Google Tasks to Bitquery. A trigger fires from one place; an action lands in another.
Google Tasks triggers
Bitquery actions
Recurring trigger
Notis starts this workflow on a schedule, such as daily, weekly, or during business hours.
Aliases Metric
Tool to use graphql aliases to rename fields in the response for clarity and disambiguation. use when you need to query multiple metrics with identical field names in one call.
Webhook trigger
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Archive Database Query
Tool to query the archive database. use when you need full historical blockchain data (delayed by tens of minutes to hours).
New Task Created
Triggers when a new task is created in a Google Tasks list. Uses timestamp filtering (updatedMin) to efficiently detect new tasks.
Combined Database Query
Tool to query the combined database, which merges archive and real-time databases. use when you need both historical and up-to-the-second blockchain data in one request.
New Task List Created
Triggers when a new Google Tasks task list is created. This trigger monitors Google Tasks and fires when new task lists are detected.
Conditional Metrics Snippet
Tool to generate a graphql metric snippet with conditional logic. use when you need to apply filters directly on metric calculations via the `if` attribute.
Task Details Changed
Triggers when a specific task's details change. This trigger monitors a single Google Task and fires when any of its details (title, notes, status, due date, completion, position) are modified.
Count Distinct Metric
Tool to use the count distinct metric to aggregate unique values for a field. use when you need to count the number of unique occurrences in a dataset.
Task List Changed
Triggers when a task list changes (title or content updates). This trigger monitors a specific Google Tasks list and fires when changes are detected.
Count Metric
Tool to use the count metric to aggregate the number of records matching a graphql query. use when you need simple record counts.
Task Updated
Triggers when an existing task is updated in a Google Tasks list. This trigger monitors a specific task list and fires when tasks are modified.
Database Selection
Tool to select the database (archive, realtime, combined) to query at the top level of a graphql request. use after determining whether you need live, historical, or combined blockchain data.
Early Access Program Query
Tool to access streaming data across various blockchain networks for evaluation purposes. use when querying chains not available via the v2 endpoint; limited to real-time data only.
