Google Slides

Google Slides for fancy-flow — as four imported, versioned packages, one per runtime. Not vendored source: a copy cannot be upgraded, and third-party APIs change.

The ui package is the editor surface and is React on every host — a PHP or Python project installs it and its own runtime package, and never the js one.

What it costs you

One dependency: @particle-academy/fancy-connector-core (or particle-academy/fancy-connector-core on Composer), which the js and php packages pull in themselves. The Python package has zero runtime dependencies.

No Google Slides SDK. Plain HTTP, deliberately: a vendor SDK is third-party code subject to the kit's full approval bar, and one per provider is hundreds of dependencies nobody is tracking.

Setting it up

Everything below is generated from provider/manifest.json, so it cannot disagree with what the packages do.

Credentials

A Google Slides connection holds 4 values.

Two kinds of value, and mixing them up matters. A provider credential is ONE value for the whole installation — an OAuth app's client secret serves every connected account. An account credential is one per connected account. A host that stores the second where it stores the first lets one account's credentials reach another's.

Authorising

Google Slides uses OAuth2 (authorization_code). The package DECLARES the exchange; the HOST performs it — a consent screen needs a browser, a redirect URI and somewhere to persist the result, and all three belong to the host.

• Authorize URL — https://accounts.google.com/o/oauth2/v2/auth
• Token URL — https://oauth2.googleapis.com/token
• Scopes — https://www.googleapis.com/auth/presentations
• Access token lifetime — 3600 seconds (1 hours). A host that never refreshes works all afternoon and is broken by morning.

One consent grant, shared (grant: "google"). Every connector declaring the same grant can run on ONE OAuth client, with one consent and one refresh token per person.

• Authorize with access_type=offline, include_granted_scopes=true. Ask for a feature's scopes when it is first used; the new token covers every scope granted before. A refresh token comes back only on the FIRST exchange, so keep the stored one when an exchange returns none.
• Revoke — POST https://oauth2.googleapis.com/revoke with token. It removes the WHOLE grant: every connector sharing it, not only this one. A per-feature disconnect stops using that feature's scopes locally; only a full disconnect revokes.
• Identify the account by sub: request openid, then verify the token response's id_token (issuer https://accounts.google.com or accounts.google.com, keys at https://www.googleapis.com/oauth2/v3/certs, audience = clientId). Never key a connection by email.
• No restricted scopes in this connector.

The refresh tokens do not rotate: the same one is reusable, so a refresh may safely be retried and may run concurrently. Stated rather than assumed, because the opposite — a provider that spends the token and revokes the grant on a replay — looks identical until it happens.

The estate

Google Slides has no test estate, and somebody checked. Everything this connector does is real. Use the faker to build against it.

Google has no sandbox for Slides. A test presentation is a real one in a real Drive, so every create is real -- use the faker while developing and clean up any live test presentations.

What it can do

Actions

batch_update — Batch update a Google Slides presentation

Apply a list of Google Slides presentation API requests to a presentation, all or none.

POST /v1/presentations/{presentationId}:batchUpdate · unsafe to replay — a retried durable run does it TWICE

presentation_create — Google Slides presentation

Create a blank Google Slides presentation.

POST /v1/presentations · unsafe to replay — a retried durable run does it TWICE

presentation_get — Google Slides presentation

Read a presentation's slides and the objectId of every element on them -- the prerequisite for targeting a specific shape or placeholder with a future edit.

GET /v1/presentations/{presentationId} · reads only — safe to replay

text_replace — Replace text in a Google Slides presentation

Replace every occurrence of a string in a presentation.

POST /v1/presentations/{presentationId}:batchUpdate · unsafe to replay — a retried durable run does it TWICE

Run it before you have credentials

Every operation ships a faker, whether or not Google Slides has a sandbox. Set a node's mode to fake and it returns the shape Google Slides actually publishes — the same field names, deterministically — so you can wire the downstream nodes before touching an account, a key, or a network.

This repository is generated

provider/ is the source. Everything under packages/ is emitted from it and must not be hand-edited — CI regenerates and diffs on every push, and the next protocol sync destroys anything it finds. See AGENTS.md.

Two namespaces, which do not match on purpose

The repo is github.com/Fancy-Friends/google-slides; the packages publish under particle-academy. Nothing derives one from the other — the names come from weaver's friends.json and nowhere else.
