Build your first Function

This walkthrough creates a small Function with a typed input and tests its saved development version.

Demo moving from Function authoring to a persisted execution

Create the Function

Select Functions and New Function.
Set the name to Customer greeting and slug to customer-greeting.
Use this input schema:

json

{
  "type": "object",
  "properties": { "name": { "type": "string", "minLength": 1 } },
  "required": ["name"],
  "additionalProperties": false
}

Enter the handler:

ts

export default async function handler(ctx, input) {
  ctx.logger.info("Creating greeting", { requestId: ctx.invocation.requestId });
  return { greeting: `Hello, ${input.name}!` };
}

Save, then validate the Function.

Test the saved version

Open the test panel, choose a Development endpoint context, and enter:

json

{ "name": "Ada" }

Run the test and confirm the output contains Hello, Ada!. Review the log entry, duration, request ID, and execution record.
