Field Mapping

noun · also: workflow, json, payload

What is field mapping?

Field mapping is connecting an output field from one step to an input field on the next — the data plumbing of every workflow.

Definition

Full definition of field mapping

When a Stripe webhook fires, you have customer.email. When you call HubSpot Find Contact, you need email. Mapping links them. Most no-code platforms use a visual picker (click field on left, click field on right). Tiny Command also supports template expressions like {{trigger.customer.email}} for inline use in any string field.

FAQ

Common questions about field mapping

What if the field types don't match?
Add a Transform step between mapping (e.g., string → number, or split a name field into first + last).
Can I map nested fields?
Yes. Use dot notation: trigger.line_items.0.price for the first line item's price.
