Action
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.
Why this helps
A founder checking transaction fees has to leave the conversation, look up current estimates, then remember to return with an answer.
- Cuts app switching when a gas estimate is needed during a conversation.
- Uses current Blocknative estimates for requested inclusion probabilities.
- Keeps the requested check and result tied to the inbound WhatsApp message.
Setup
Build it in a few focused steps.
- 1Connect WhatsApp and Blocknative once in the Notis portal.
- 2Create an automation in Automations, New Automation, and give it a name.
- 3In one instruction, ask Notis to read inbound WhatsApp requests for gas estimates, query Blocknative for the requested inclusion probabilities, and reply with the result.
- 4Pick the WhatsApp New Message Received trigger and choose where run reports go.
- 5Test with one real WhatsApp request that specifies a chain and desired inclusion probabilities.
Questions about this workflow
Does this workflow submit or speed up a transaction?
No. It fetches gas price estimates from Blocknative and can report them in a WhatsApp reply. It does not submit or alter transactions.
What should the WhatsApp request include?
Include enough detail to make the lookup clear, such as the network and the inclusion probabilities you want. If key details are missing, have Notis ask a follow-up before querying.

Message Status Updated
Triggers when a WhatsApp message status changes. IMPORTANT LIMITATION: WhatsApp Cloud API does not provide a native polling endpoint for message status. Status updates are ONLY delivered via webhooks in real-time. This trigger cannot directly poll the WhatsApp API for status updates. This trigger will return empty results as WhatsApp does not support this operation. To track message status updates, you must: 1. Set up a webhook endpoint to receive status notifications from WhatsApp 2. Store the webhook data in your own database 3. Use a different mechanism to query your stored webhook data For more information, see: - https://developers.facebook.com/docs/whatsapp/cloud-api/webhooks
