Resend

Resend 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 Resend 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 Resend connection holds 1 value.

Every value here is account scope: one per connected account, not one per installation.

The estate

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

Resend has NO test estate, and somebody checked. Its simulator RECIPIENTS -- delivered@resend.dev, bounced@resend.dev, complained@resend.dev, suppressed@resend.dev -- are not one: the send is real, it is billed, and it counts against the quota. Modelling them as a sandbox would put a live send behind a control labelled "test", so mode does not offer sandbox at all and fake is the primary development mode rather than the fallback.

What it can do

Actions

email_send — Send email

Send an email through Resend.

POST /emails · idempotent — safe to replay

Run it before you have credentials

Every operation ships a faker, whether or not Resend has a sandbox. Set a node's mode to fake and it returns the shape Resend 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/resend; the packages publish under particle-academy. Nothing derives one from the other — the names come from weaver's friends.json and nowhere else.
