What is the Little Outreach API playground?

It is a browser page on https://www.littleoutreach.com that sends same-origin HTTP requests to /api/v1 with your API key in the Authorization header, matching the published OpenAPI specification.

How do I provide my API key in the playground?

Paste your key into the API key field, or sign in to load it from your Account. The page sends Authorization: Bearer with that value.

This page is the full-surface playground: every method, any path. Most tasks are simpler in a resource-scoped playground, which replaces JSON blobs with labelled form fields.

The generic form below calls the same /api/v1 surface we run in production — send Authorization: Bearer … on every request. For concepts and every path, see API documentation.

No session. Paste an API key below, or sign in to load your key from Account automatically.
