Apply a Brex budget revision from a request
Send Notis the budget revision with the budget identifier and new details. It updates Brex and reports back.
Trigger
Webhook received
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Action
Update Budget
Update budget details.
Why this helps
Budget changes can be agreed in a conversation but forgotten before they are reflected in Brex.
- Carry an agreed revision into Brex.
- Keep the budget identifier with the requested changes.
- See the run outcome without checking repeatedly.
Setup
Build it in a few focused steps.
- 1Connect Google Calendar and Brex once in the Notis portal.
- 2Create an automation in Automations, New Automation, and give it a name.
- 3Tell Notis to update the identified Brex budget using only the revised details in the request.
- 4Choose the webhook trigger and report channel.
- 5Test with one real budget revision.
Questions about this workflow
Can Notis decide whether a change is approved?
No. Start the automation only with an authorized revision request.
What if the request does not identify the budget?
Include enough information to identify the budget and the new details. Notis can report the request for follow-up if it cannot identify it.
