Milestone 0: import zappier billing, Verae middleware, and Zapier research

Compose-ready workspace: packages/zappier (rate card, portal, Stripe),
packages/verae-zapier-middleware (timestamp + NATS), packages/verae-zapier
(CLI app), vendor/zapier-platform, and research/zapier vendor corpus.

Gate 0 structure checks pass. Product code and research are not yet wired.

# User migrations must stay within the same major version
> The Platform UI and CLI now block migrating users when the source and target integration versions differ in their [semantic major version](/integrations/manage/versions#version-numbering)—for example, you cannot migrate from `1.x.x` to `2.x.x`.
*Effective: 2026-02-26*
## Same-major-version migrations only
* Migrations are only allowed when the **from** and **to** versions share the same major number (e.g. `1.0.0``1.0.1`, or `2.1.0``2.2.0`).
* Cross-major moves (e.g. `1.5.0``2.0.0`) are blocked in both the [Platform UI](https://zapier.com/app/developer) and via [`zapier-platform migrate`](https://github.com/zapier/zapier-platform/blob/main/packages/cli/docs/cli.md#migrate). This aligns with long-standing guidance; major releases include [breaking changes](/integrations/manage/planning-changes), so users should [update Zap workflows manually](https://help.zapier.com/hc/en-us/articles/18755649454989-App-versions-in-Zapier) or you should use [deprecation](/integrations/manage/versions#deprecating-versions) instead of migration.
* Details and workflow are in [Migrate users to a new version](/integrations/manage/migrate).

# Pushing unlabelled semantic versions must be sequential
> Unlabelled integration versions must be published in order via `zapier-platform push`.
*Effective: 2026-02-23*
## What changed
These rules apply to **unlabelled** [semantic versions](/integrations/manage/versions#version-numbering) only (for example `1.2.3`). **[Labelled versions](/integrations/manage/labeled-versions)** (such as `1.2.3-beta` or `0.0.0-my-feature`) are not part of these checks.
When you push a new unlabelled version, the platform validates **two** things in addition to existing format checks.
### 1. You cannot skip a required predecessor
The API must see the right **previous** unlabelled release before it accepts the new one:
* **Patch bump** (`1.2.3`): the exact unlabelled `1.2.2` must already exist.
* **Minor bump** (`1.3.0`): at least one unlabelled `1.2.x` must exist.
* **Major bump** (`2.0.0` when coming from `1.x`): at least one unlabelled `1.x.x` must exist.
`1.0.0` is unchanged: there is no prior semver to require.
If the predecessor is missing, push fails with **403** and guidance like: *Version X requires Y to exist. Push version Y, then try again.*
### 2. You cannot insert an “intermediate” version behind a newer line
You also cannot push a version if a **newer** unlabelled version already exists in the segment that would make yours a backward insert:
* **`1.2.3`**: blocked if any unlabelled **`1.2.4` or higher** on the same `1.2.*` line already exists. Pushing **`1.3.0`** is still allowed when only `1.3.x` or `2.x.x` exists—those are not on the `1.2.*` patch line.
* **`1.3.0`**: blocked if any unlabelled **`1.4.x` or higher** on the same major (`1.*`) already exists. **`2.0.0`** is still allowed when only `2.x.x` exists.
* **`2.0.0`**: blocked if any unlabelled **`3.x.x` or higher** already exists.
If that applies, push fails with **403** and a message that an existing version would make this an intermediate release, which is not allowed.
## What this means for you
* Plan **patch → patch → minor → major** (or the minimal chain your history needs) using **unlabelled** semver when you are ready to record real releases; use **labelled** snapshots while iterating.
* If you are stuck because old versions were removed, you may still use **[deprecation](/integrations/manage/versions#deprecating-versions)** and, when appropriate, **[delete a deprecated version](/integrations/manage/deprecate#deleting-deprecated-versions)** so your remaining unlabelled history matches what you want to push next.

# What's changed in v18.0.7
> Publishing process improvements, refactoring, and `sample` field added to dynamic `outputFields`.
*Released: 2026-01-07*
In response to the previous [Shai-Hulud incident](/integrations/build-cli/inc-547), we're changing our package publishing process to improve security. This release also includes a schema extension that allows `outputFields` to have a `sample` field. Lastly, we've refactored the `invoke` command to make upcoming enhancements easier.
## cli
* 🔨 Refactor `invoke` command ([#1217](https://github.com/zapier/zapier-platform/pull/1217))
## core
None!
## schema
* 🎉 Allow a `sample` field to be provided for dynamic `outputFields` ([#1211](https://github.com/zapier/zapier-platform/pull/1211))
## misc
* 🔨 Add publish job in CI ([#1212](https://github.com/zapier/zapier-platform/pull/1212), [#1223](https://github.com/zapier/zapier-platform/pull/1223))

# What's changed in v18.1.0
> New `invoke --remote` flag and a fix on package manager detection.
*Released: 2026-01-19*
The `zapier-platform invoke` command now supports a **remote mode**. By adding a `--remote` (`-r` for short) flag to the `invoke` command, such as:
```
zapier-platform invoke -r
```
... all invocations, including trigger/action invocation itself, input field definitions, and dynamic dropdown choices, will be executed remotely by the Zapier production environment. This means:
* The integration version you want to test has to be deployed first.
* The invocation results and the bundle payload passed to your integration code will match what you see in live production, which is great for testing.
* Remote mode is slower than local mode (without the `-r` flag).
Read more about the three different modes in the [`zapier-platform invoke --help`](https://github.com/zapier/zapier-platform/blob/main/packages/cli/docs/cli.md#invoke) documentation.
We also fixed an issue where the `build` and `test` commands were not correctly detecting package managers (like npm, yarn, pnpm, or bun) when your integration was part of a monorepo. Now, the CLI doesn't just look in the current directory for package manager indicators (like `package-lock.json` for npm), but also checks parent directories up to four levels up.
## cli
* 🎉 Add `--remote` flag to `invoke` command ([#1220](https://github.com/zapier/zapier-platform/pull/1220))
* 🐛 Fix package manager detection in `build` and `test` commands to include parent directories ([#1225](https://github.com/zapier/zapier-platform/pull/1225))

# What's changed in v18.4.0
> JSON input field type, `versions` command improvements, function-based dynamic dropdown fix
*Released: 2026-04-06*
This release introduces the new `json` input field type, improved `zapier versions` output, and a schema validation fix.
You can now accept structured JSON input from users with the new [`json` field type](/integrations/build-cli/input-fields#json-fields). Optionally provide a `schema` to validate and describe the expected shape:
```javascript theme={null}
{
key: 'product',
type: 'json',
label: 'Product',
helpText: 'Enter a JSON object',
schema: {
type: 'object',
properties: {
name: { type: 'string' },
price: { type: 'integer' },
},
required: ['name'],
},
}
```
We also fixed a bug where pushing code with [function-based dynamic dropdowns](/integrations/build-cli/dynamic-dropdowns#function-based-dynamic-dropdowns-perform) caused an unexpected validation error on the server. If you want to use function-based dynamic dropdowns, upgrade to 18.4.0 or later:
```javascript theme={null}
{
key: 'project_id',
label: 'Project',
type: 'string',
required: true,
choices: {
perform: async (z, bundle) => {
const response = await z.request('https://api.example.com/projects');
return {
results: response.data.map((project) => ({
id: project.id,
label: project.name,
})),
paging_token: null,
};
},
},
}

# What's changed in v18.5.0
> Line item support in `invoke`, falsy value fixes, new `line-items` project template
*Released: 2026-04-16*
This release adds line item support to the `zapier-platform invoke` command and bumps `lodash` across all packages to address a security vulnerability.
[Line items](/integrations/build-cli/input-fields#line-items) are fields with a `children` property that represent structured, repeating data — like rows in a spreadsheet or items in an order. The `invoke` command now supports them in both interactive and non-interactive modes:
```bash theme={null}
# Non-interactive: pass line items as JSON
zapier-platform invoke create order --non-interactive \
-i '{"name": "My Order", "line_items": [{"product_name": "Pens", "quantity": "12", "price": "1.50"}]}'
# Interactive: use the line item editing UI
zapier-platform invoke create order -i '{"name": "My Order"}'
```
In interactive mode, a sub-menu lets you add, edit, and delete items with per-field editing and required field validation.
## cli
* 🎉 Add line item support to `invoke` command with interactive editing UI ([#1272](https://github.com/zapier/zapier-platform/pull/1272))
* 🎉 Add `line-items` project template for `zapier-platform init` ([#1272](https://github.com/zapier/zapier-platform/pull/1272))
* 🐛 Fix `invoke` bugs: auto-detect auth ID for no-auth apps in remote mode, falsy value handling (`0`, `false`) causing infinite dropdown re-prompting, and more ([#1272](https://github.com/zapier/zapier-platform/pull/1272))

# What's changed in v18.5.1
> Actionable error when app definition fails to load, `platformData` removed from bundle, docs and `help` updated to use `zapier-platform` binary name
*Released: 2026-04-30*
This patch release improves the error message you get when an app definition fails to load, removes `platformData` from the bundle, and finishes the rename of the CLI binary from `zapier` to `zapier-platform` across docs and the `help` command.
We're renaming `zapier` to `zapier-platform` because the `zapier` binary name will be allocated to the [Zapier SDK](https://docs.zapier.com/sdk). The `zapier` binary still works in v18, but in the next major release (v19), we'll officially remove it — you'll need to use `zapier-platform` instead. If `zapier-platform` is too long to type, you can set up a shell alias like `alias zp=zapier-platform`.
## cli
* 📜 Rename binary name from `zapier` to `zapier-platform` in docs, source, and `help` command ([#1291](https://github.com/zapier/zapier-platform/pull/1291), [#1292](https://github.com/zapier/zapier-platform/pull/1292), [#1293](https://github.com/zapier/zapier-platform/pull/1293))

# What's changed in v18.6.0
> New `invoke auth template` and `invoke auth render` commands for inspecting an app's auth request shape
*Released: 2026-05-05*
This release adds two new commands that let you inspect and render the authentication request your app produces. They run your app's middleware (`beforeRequest`, `getAccessToken`, etc.) with placeholder credentials and capture the resulting auth request shape (headers, query params, and body) without making a real network call.
`zapier-platform invoke auth template` returns the static template (with `{{placeholders}}` for auth fields). `zapier-platform invoke auth render` substitutes real auth data from .env into that template and returns the final request.
## cli
* 🎉 Add `invoke auth template` and `invoke auth render` commands ([#1282](https://github.com/zapier/zapier-platform/pull/1282))

# What's changed in v19.0.0
> The `zapier` CLI binary has been removed. Use `zapier-platform` instead.
*Released: 2026-05-18*
Version 19.0.0 is a **BREAKING CHANGE** release. Here is a brief breakdown of the main change (**❗ denotes a breaking change**):
## ❗ The `zapier` binary has been removed
The `zapier` command was deprecated in v18.0.0 in favor of `zapier-platform`. v19 completes that transition by removing the old binary entirely.
***
Apart from this major change, here are the detailed release notes for this release (**note that ❗ denotes a breaking change**):
## cli
* ❗ Remove the `zapier` executable; the CLI now ships only `zapier-platform` ([#1299](https://github.com/zapier/zapier-platform/pull/1299))
## core
None!
## schema
None!

# What's changed in v19.1.0
> Auth template rendering can honor the real outbound request and custom request properties, plus a fix for the `appTester` type signature
*Released: 2026-07-30*
This release improves auth template extraction and rendering: templates can now honor the real outbound request and integration-specific custom request properties when selecting credentials, non-auth request bodies are kept out of extracted templates, and `z.request(url, options)` calls are handled correctly during extraction. It also fixes the `appTester` TypeScript signature to accept request templates.
## cli
None!
## core
* Thread `targetRequest` through `renderAuthTemplate` so rendering can honor the real outbound request ([#1298](https://github.com/zapier/zapier-platform/pull/1298))
* Support `customRequestProperties` in the `renderAuthTemplate` bundle, letting integration middleware select the right credential during rendering ([#1322](https://github.com/zapier/zapier-platform/pull/1322))
* Drop non-auth request bodies from extracted auth templates ([#1323](https://github.com/zapier/zapier-platform/pull/1323))
* Preserve `z.request(url, options)` options in auth-template request stubs, and honor `customRequestProperties` during template extraction ([#1324](https://github.com/zapier/zapier-platform/pull/1324))
* Support request templates in the `appTester` type signature ([#1302](https://github.com/zapier/zapier-platform/pull/1302))

# New platform guardrails for safer integration versioning
> The platform now checks for breaking changes during promotion and guides you toward the correct semantic version, helping protect your users from unexpected disruptions.
*Effective: 2026-05-12*
## What's new
The platform now automatically checks for breaking changes when you [promote](/integrations/manage/promote) a new integration version. If breaking changes are found and the version doesn't increment the major number, promotion is paused with a clear explanation of what was detected and which version number to use instead.
This helps you catch issues **before** they reach users — no more accidentally shipping a removal or auth change under a patch bump.
## What gets checked
When you promote, the platform compares the new version against the current public version at the **schema level** — looking at the structure of your triggers, actions, searches, and authentication. The following schema-level breaking changes are detected automatically:
* **Removed triggers, actions, or searches** — a key present in the current public version is missing in the new version
* **Authentication type change** — the auth type (e.g., `oauth2`, `apiKey`, `session`) differs between versions
* **Trigger type change** — a trigger switched between polling and hook type
* **Removed searchOrCreate keys** — a searchOrCreate present in the current version is missing
* **Removed input field keys** — an input field key on an existing trigger/action was removed
* **Optional input field made required without a default** — an existing optional field is now required but has no default value
* **Authentication field changes** — removing an auth field, adding a new required auth field, or changing an auth field's type
* **Input field type changes** — changing the type of an input field (e.g., `string``list`)
* **Incompatible JSON field schema changes** — backward-incompatible changes to `json`-type input field schemas
If any of these are detected, you'll see a message explaining the specific changes found and the minimum major version required.
<Note>
These checks cover **schema-level** changes only. Some breaking changes happen outside the schema — for example, removing or renaming output field keys, changing the behavior of a perform function, or altering response structures. These are still your responsibility to catch. Review the full [versioning matrix](/integrations/manage/planning-changes) before promoting.
</Note>
## What this means for you
* **If you're already following semver**, nothing changes. You're good.
* **If a promotion is paused**, read the message — it tells you exactly which changes triggered the check and what version number to use. Bump the major version and promote again.
* **If you need to phase out a trigger, action, or search without a major bump**, [hide it](/integrations/manage/versions#what-counts-as-a-breaking-change) instead of removing it. Hidden items continue to work for existing Zap workflows but are no longer available to new users.
For the full list of what gets detected and how to choose the right version number, see [Version numbering](/integrations/manage/versions#version-numbering).
