# How to Design a Workflow: Best Practices and Patterns

Designing an effective workflow is about balancing structure, flexibility, and clarity. In the XYB platform, workflows give teams control over core logic but with that power comes responsibility to ensure workflows are maintainable, observable, and secure.

This guide outlines key principles and common patterns to help teams design workflows that scale.

**1. Define the Goal**

Start with a clear, outcome-focused goal:

* What process are you trying to automate?
* What services will be involved?
* What is the desired end state?

Example:

> "When a customer is flagged RiskClosed, close all associated investigation tasks."

**2. Choose the Right Trigger (if applicable)**

Some workflows begin with a service event, others are internal processes. Determine whether your workflow is:

* Service-driven (e.g. entity created, payment initiated)
* Scheduled (e.g. rotate secrets weekly)
* Manual (e.g. operator triggers the flow)

**3. Break It Into Steps**

Decompose the workflow into logical stages:

* Input validation
* Risk or eligibility checks
* Routing or decision branches
* Execution actions (create task, update status)

Use **sequence** contexts for ordered steps, and **selection** contexts to branch.

**4. Use Parameters for Flexibility**

Avoid hardcoding logic inside a workflow. Use parameterized values for things like:

* Thresholds (e.g. transaction size limits)
* Recipient accounts or task templates
* Provider selection

Parameters can be adjusted per workflow version or client without code changes.

**5. Handle Failures Gracefully**

Services should handle retries and timeouts, but workflows should:

* Detect known error conditions
* Set workflow states appropriately
* Avoid infinite loops or recursion

Workflows can use the ENDING state or terminal transitions to mark completion.

**6. Reuse Through Templates**

Abstract repeated logic into reusable templates. Examples:

* Standard ledger validation block
* Common risk escalation flow
* Account + wallet creation bundle

Templates reduce duplication and improve quality.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.xyb.co/xyb-payments/payment-workflows-and-automations/how-to-design-a-workflow-best-practices-and-patterns.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
