Payload

noun · also: webhook, json, trigger

What is payload?

The payload is the data content of an HTTP request or webhook — the JSON inside the request body.

Definition

Full definition of payload

When a webhook fires, the "payload" is the JSON object describing what happened. When you send a request, the payload is the body you POST. Most integration debugging boils down to inspecting payloads: what did the upstream system send, and what does the downstream system expect? Tiny Command shows the full payload for every step run, making this trivial.

FAQ

Common questions about payload

How big can a payload be?
Most APIs cap at 1-10 MB. Larger files get sent as URLs to download separately.
Why is my payload missing fields?
Some APIs only return a default set of fields. Pass a fields= parameter or expand= flag to get more.
