Node reference

Execution nodes are the building blocks that come after a workflow’s trigger: they perform actions, transform data, or control the workflow. This page lists all fifteen, grouped by purpose.

Nodes that call protected services — external APIs, messaging platforms, tracking providers, or Fail Fast itself — authenticate with credentials. You choose or create the credential inside the node’s configuration.

Node	What it does	When to use it
Switch	Branches the workflow between paths based on conditions.	When different situations need different handling — route each run down the path whose condition matches.
Code	Runs JavaScript to transform the previous node’s output.	When you need custom reshaping, calculations, or formatting that no other node covers.
Call Another Workflow	Invokes another workflow as a step.	When you have reusable logic built as a sub-workflow — the other workflow must start with the When Executed By Another Workflow trigger.

Node	What it does	When to use it
HTTP Request	Calls external APIs or services.	When you need to reach a system that has no dedicated node.
OpenAI	Generates text with language models.	When a step needs generated or interpreted text — summaries, drafts, classifications.
WhatsApp	Sends WhatsApp template messages or replies to conversations.	When an automation should message people on WhatsApp — see WhatsApp chats for the inbox side.
Notification	Sends in-app notifications to users or roles.	When teammates should be alerted inside Fail Fast about something the workflow detected or did.
Truora	Makes requests to Truora, a background-check and identity-validation service.	When a flow needs to verify a person’s identity or run a background check.

Node	What it does	When to use it
Validate Document	Validates documents against predefined rules.	When uploaded documents must meet requirements before a process continues.
When Document Near Expiry	Runs when a document approaches its expiration date.	When you want to act ahead of expirations — renewals, reminders, compliance checks.

Node	What it does	When to use it
Fail Fast	Makes requests to Fail Fast itself.	When the workflow should act on your own workspace’s data as part of the automation.

Node	What it does	When to use it
RNDC	Connects to the Registro Nacional de Despachos de Carga — the Ministry of Transport’s freight registry — via its web service.	When freight dispatch operations must be registered or consulted with RNDC.
Satrack	Retrieves vehicle tracking data — last known location, or events within a date range.	When a flow needs to know where a vehicle is or what happened during a period.
Monitor	Handles tracking and dispatch through the Monitor platform.	When your operation runs tracking or dispatch on Monitor.
Integrador Transporte	A generic node for transport tracking providers.	When your tracking provider isn’t covered by a dedicated node.

See Fleet monitoring for how tracking fits into the transport module.

Picking the right node

Start with the most specific node available: WhatsApp over HTTP Request for WhatsApp messages, Satrack over a generic call for Satrack data.
Reach for HTTP Request or Integrador Transporte when no dedicated node exists for your service.
Use Code sparingly — only when the data shape between two nodes genuinely needs custom transformation.
Use Switch whenever one workflow must handle several cases; it keeps the logic on the canvas where anyone can read it.
