Function
Code
import { inputs, queries, type FunctionResult } from "@budibase/functions"export default async function (): Promise<FunctionResult> {const { workOrderId, partNumber, requestedQuantity } = inputsif (!workOrderId || !partNumber || !requestedQuantity || requestedQuantity <= 0) {return { output: { status: "invalid_request" } }}const order = await queries.Maintenance.getWorkOrder({ workOrderId })const stock = await queries.Inventory.getPartStock({ partNumber })const available = stock.data[0]?.availableQuantity ?? 0return {output: {workOrder: order.data,availableQuantity: available,status: available >= requestedQuantity ? "in_stock" : "replenish",needsReview: inputs.safetyCritical || available < requestedQuantity,},}}
Function queries
Select the example queries to include.
Generate functions with AI
Describe the logic you need, then review, refine, and test the generated code before putting it to work.
Works seamlessly with apps, automations and agents
Bring your custom logic into the apps, automations, and agents that power your processes.

You have questions. We have answers.
What can I build with functions?
Write JavaScript for the business rules, calculations, validation, and data transformations your processes need. Use functions within automations to add custom logic to a workflow.
Can AI generate a function for me?
Yes. Describe the logic you need and generate a function with AI. Review the code, adjust it to your requirements, and test it before using it in your process.
Can I version my functions?
Yes. Version your functions to keep track of changes as your logic evolves. Function versioning tracks your code changes within Budibase.
How can I get help debugging a function?
Copy your code and the relevant error into your preferred AI assistant. Use its suggestions to troubleshoot the issue, then review and test any changes in Budibase.
How do I trigger a function?
Add your function to an automation. The automation's trigger determines when it runs, including CRON schedules, webhooks, and data changes.
