Boom scores A on Supergood's API Report Card. Boom ships public OpenAPI specs, a sandbox, self-serve webhooks and an official OAuth MCP server, and customers mint scoped API keys in Settings without a ticket. Prospective partners still onboard through a partnerships review, pricing is unpublished and there is no client SDK.
Boom has a workable official integration path. Most engineering teams can build against it directly. Open API: self-serve, documented, with SDKs
Boom (boompay.app) is an Austin, Texas proptech company that sells a leasing operating system to property managers.
Real Estate & Property. A property manager syndicates listings and routes inbound leads into BoomCRM, where an AI leasing agent answers calls and schedules tours.
Boom's August 2026 Series A announcement states it runs screening for more than 400 operators covering over 500,000 units, with more than 3 million applicant verifications completed, and the homepage cites 500+ operators.
Leads and owner leads with showings, communications, notes and identity verifications, lead sources and stages, magic links, applicants and applications with consumer report data (credit report and score, criminal, eviction, income verification), screening decisions and decision criteria outcomes, properties, units, listings and property groups, activity logs, billing statements and payout bank accounts, rent reporting customers and enrollments, monthly rental payment verifications, furnishment results per bureau, and the PMS sync records that push approved applicants into Buildium, Rent Manager, Yardi, ResMan, Rentvine and other systems.
Boom was founded in 2020 as a consumer rent reporting app and expanded into property manager tooling with BoomScreen, then BoomCRM in August 2026 alongside a $15 million Series A led by S3 Ventures.
An independent property management API grader's September 2026 run found the rent reporting spec disagreeing with the live API on types and host, dead tunnel URLs on the docs endpoint pages, no Retry-After header and no request id on successful responses; Boom's late September 2026 docs overhaul replaced the spec, removed the dead pages and added both headers. The same review found no idempotency key on the calls that file rent payments to the bureaus or approve applications and no concurrency control such as ETags, and Boom's current error guide confirms the API does not yet accept an idempotency key. Full sourced list under Sources below.
Common alternatives include Esusu, Findigs, TransUnion SmartMove, Snappt, Funnel Leasing, Knock CRM. Graded alternatives appear under "More from the report card" below.
Supergood's grades measure one thing: can a customer's engineering team get their own data out programmatically? Supergood checks six things (whether a real API exists, how access is gated, data coverage, auth quality, docs and developer experience, and stability) and rolls them into a letter grade. Supergood re-verifies grades, and they only move on evidence.
Boom is a cloud platform. The vendor hosts it and customers use it through a browser or a vendor-run app, so there is no customer-managed server involved. Boom is cloud only. Property managers use BoomCRM, BoomScreen and BoomReport through the vendor-hosted Boom Partner Platform and a vendor-run API with sandbox and production hosts.
Boom scores GOOD on MCP availability. Boom operates an official remote MCP server at mcp.boompay.app/mcp over Streamable HTTP, documented at docs.boompay.app/mcp with setup steps for Claude, ChatGPT, Claude Code and Codex, and announced on October 21, 2026 as included for Boom customers at no additional cost. Sign in is OAuth 2.0: the server publishes protected resource metadata pointing at mcpauth.boompay.app, which advertises the authorization code grant with PKCE S256, refresh tokens and client credentials, and the consent screen lists seven scopes (leads read, create and update, showings read, and funnel, call and listing reports). Tools cover searching, creating and updating leads, matching a free text property or unit mention to an active listing, lead sources and stages, adding and reading lead notes, property search and six leasing reports (showing activity, no-shows, lead to application conversion, time in stage, application pipeline and new applications), scoped to the user's own Boom permissions; three tools write data. The connector does not return screening results such as credit, income, background or identity data, and it does not reach BoomReport rent reporting. Boom is not listed in the official MCP registry.
Yes. Boom publishes an official MCP server, so MCP clients like Claude, Cursor, and Codex can connect to it directly. Setup instructions are in the vendor's documentation.
