Planning Center

Planning Center is a suite of church management software products - People, Services, Giving, Groups, Check-Ins, Calendar, Registrations, and Publishing - used by churches to organize their people, plan worship services, process online giving, run small groups, manage attendance and check-in, schedule facilities and events, handle event registrations, and publish sermons. Each product exposes a documented public REST API under a shared base URL (https://api.planningcenteronline.com), authenticated with OAuth 2.0 or a Personal Access Token and returning data in the JSON:API 1.0 format. A Webhooks API delivers create/update/destroy events across the products. The APIs are free to use with a Planning Center account; each product is subscribed to separately.

agent ready

Limited machine-readable signal and partial portal coverage — documentation a human can read, but little a machine or agent can consume without scraping.

Kin Score

API Evangelist profiles Planning Center the way a machine reads it — 19 machine-readable artifacts across 9 APIs, pulled from the provider's own public surface and indexed so a developer, an analyst, or an AI agent can evaluate it against every other provider on the network.

Every provider in the network is reduced to the same set of machine-readable artifacts — OpenAPI contracts, event specifications, GraphQL schemas, runnable collections, pricing and rate-limit signals, security posture, OAuth scopes, and the agent surfaces (MCP servers and skills) that let software drive the API on its own. We profile them because the interface is the part of a company you can actually inspect: it is a truer signal of what a provider does than any marketing page. From those artifacts we compute the Kin Score — Planning Center scores 39.6/100 (thin), with a separate agent-readiness read of 48/100 (agent ready). The full breakdown is below, followed by every artifact we hold — each card links through to its machine-readable definition on apis.io.

Kin Score

This is the API Evangelist rating — a single, repeatable read computed from the artifacts on this page. Green fill is points earned; the red track is points possible, so every bar shows earned-versus-possible at a glance.

How we profile Planning Center

Each block below is one kind of artifact we hold for Planning Center. For each we say what it is and why it earns a place in the profile, then list every one we've indexed — capped at two rows, scroll within the panel for the rest.

APIs 9

Each API is captured as its own OpenAPI definition — every operation, parameter, and response. This is the single most useful machine-readable description of what an API does, and it's what lets us score, lint, mock, and generate against it without asking the provider for anything.

Individual APIs this provider publishes, each with its own machine-readable definition.

Planning Center Calendar API

Church calendaring, events, and facility resources.

Planning Center Check-Ins API

Attendance, events, locations, and stations.

Planning Center Giving API

Donations, funds, batches, payment sources, and pledges.

Planning Center Groups API

Small groups, memberships, and group events.

Planning Center People API

People, households, contact info, lists, forms, and workflows.

Planning Center Publishing API

Sermon channels, series, episodes, and speakers (read-only).

Planning Center Registrations API

Event signups, attendees, categories, and campuses.

Planning Center Services API

Service planning - service types, plans, songs, teams.

Planning Center Webhooks API

Cross-product event subscriptions and deliveries.

Open Collections 1

Open, tool-agnostic collections carry the same runnable value as Postman without locking you to one client — the portable, forkable form of the same exercise.

Open, tool-agnostic API collections (OpenAPI-derived and Bruno).

OPEN COLLECTION

Pricing Plans 1

Pricing is part of the interface. Machine-readable plans tell you what a tier costs and includes before you commit — one of the six things the Kin Score reads for commercial clarity.

Published pricing tiers and plan structures.

Rate Limits 1

Rate limits are the difference between a demo that works and a production integration that doesn't fall over. Publishing them is an operational-transparency signal — and a hard requirement for any agent that plans its own throughput.

Documented rate limits and quota policies.

FinOps 1

Cost, billing, and metering signals let a buyer model the financial operations of an API before it's live. We profile them for the same reason we profile pricing: the money is part of the contract.

Cost, billing, and metering signals for API financial operations.

Security Posture 4

Authentication, domain security, vulnerability disclosure, and trust-center signals — the evidence that a provider takes security seriously enough to document it. We profile it because you can't govern what you can't see.

Scopes 1

OAuth scopes are the vocabulary of least-privilege access. Profiling them shows exactly what an integration — or an agent acting on a user's behalf — is allowed to do.

Agentic Access 1

An x-agentic-access contract marks which operations are safe for an agent to run on its own and which need a human in the loop. It is the difference between an API an agent can use and one it can use safely.
