The FlipperForce Public API is the REST API behind Upright's (formerly Fund That Flip's) FlipperForce project management platform for real estate redevelopers. It exposes 50 operations across projects, expense transactions and line items, expense categories and accounts, project income, receipts, photo logs, project updates, companies and company categories, file upload intents, the user account and the workspace activity log. Access is by request only: a workspace owner requests a Public API key from Workspace Settings > Integrations, and the key is sent as an HTTP Bearer token.
FlipperForce Public API is published by Fund That Flip on the APIs.io network, described by a machine-readable OpenAPI specification.
Tagged areas include Project, Expenses, Income, Receipts, and Photos. The published artifact set on APIs.io includes an OpenAPI specification, an API reference, and API documentation.

ⓘWhere this information came from
This is an independent, third-party profile of FlipperForce Public API, published by
API Evangelist. We do not operate, host, resell, or
support these APIs, and we are not affiliated with or endorsed by the company unless stated above.
Everything here is built from publicly available information — the company's own site,
developer portal, documentation, public repositories, and the specifications it publishes for public use.
Nothing is obtained by breaching a system, defeating an access control, or using credentials.
The Kin Score and Agent Readiness rating are independently calculated assessments of a company's
public API artifacts, scored against a published rubric. They are not certifications,
endorsements, security assessments, or audits.
Corrections, re-scores, and removal are free — no partnership or purchase required, and
you do not need to justify the request. A removed company is recorded as unrated, never scored
zero for having asked. Acknowledgement within one business day; removal within two.
