A workflow is a visual program made of blocks. It's where you compose everything else in AACFlow.io, data, operations, integrations, and AI agents, into a process, and bind it to a trigger so it runs.
What you will learn
Read a workflow
Blocks are steps, some blocks are triggers, and connections wire them into an order that runs.
Follow the data
Each block has parameters and produces an output. A later block reads an earlier output with a connection tag.
See how it executes
Independent blocks run at once; a block waits only for what it depends on. Every run is recorded in the logs.
The pieces
- A workflow is a visual program, you build it by placing and wiring blocks, not by writing a script.
- It's made of blocks, each one a step. Some blocks are triggers: they decide what starts the run and what it receives.
- Connections link blocks together. They set the order: a block runs after the blocks wired into it finish.
- Blocks have parameters that configure how they work. A Fetch Webpage block takes a URL; an Agent block takes a model and a prompt.
- When a workflow runs, AACFlow.io records what each block produced. Any later block can read an earlier block's output through a connection tag, like
<fetch.content>. - Everything that happened is saved in the logs, the trigger, every block, and each block's input and output, so you can see exactly where a value came from.
Here's a small workflow you can read top to bottom, blocks wired in order, each one a step. The highlighted block reads an earlier block's output through a connection tag:
How execution flows
A block waits only for the blocks it depends on, nothing else.
So if A feeds both B and C, then B and C start at the same moment A finishes; they don't wait for each other. And if B and C both feed D, then D waits for both before it runs. The shape of the connections is the execution plan.
Branches, loops, and parallel
From those primitives you get expressive control flow: branch down one path or another with a Condition or Router, loop over a list, run work in parallel across many items. These are the expressive core of what you'll build, and they're all just blocks and connections.
Everything complicated: an automated software factory, an autonomous triage system that takes action on its own, is built from these same simple primitives. You start with a few blocks; the platform scales to your ambition. As you get more comfortable, the workflows you compose get richer, more branches, more agents, more reach, without ever leaving the same model you learned here. We're glad you're on this journey: AACFlow.io is built of simple primitives that compose into anything you can imagine.
