## What it does

The skill separates three scenarios that people usually lump under one name. Organization Embedded Signup starts in the Sent dashboard and connects the org's WABA through the hosted Meta flow. Organization WABA inheritance creates a child profile via `POST /v3/profiles` with `whatsapp_business_account` omitted, so the child shares the org's WABA. A dedicated child-profile WABA passes `waba_id` and `access_token` explicitly, and `phone_number_id` is optional.

Auth is either a profile key in `x-api-key`, or an organization key plus `x-profile-id` when acting for an existing child profile. Only organization keys may send `x-profile-id`; a profile key gets `403`. Omit credentials while the organization has no connected WABA and profile creation returns `422` — check the connection first instead of hunting for a public Embedded Signup endpoint, because there isn't one.

Inject the WABA token from a secret manager. Never log it, echo it, return it to the browser or keep it in general profile storage. Finishing a profile means `POST /v3/profiles/{profileId}/complete` with a required `webHookUrl`; a `202` only says background processing started, and the final state arrives in a callback whose envelope uses `event` (`COMPLETED`, `SUBMITTED`, `failed`). Make callback processing idempotent.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add sentdm/sent-plugin --skill waba-embedded-signup -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/waba-embedded-signup/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/waba-embedded-signup/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add sentdm/sent-plugin --skill waba-embedded-signup -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/waba-embedded-signup/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add sentdm/sent-plugin --skill waba-embedded-signup -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/waba-embedded-signup/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install sentdm/sent-plugin waba-embedded-signup
```

2. **Manually: put the files in place**
- File: `.github/skills/waba-embedded-signup/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add sentdm/sent-plugin --skill waba-embedded-signup -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/sentdm/sent-plugin --path skills/waba-embedded-signup
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/waba-embedded-signup/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add sentdm/sent-plugin --skill waba-embedded-signup -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

## When to use it
- tell the three WABA onboarding paths apart
- create a child profile that inherits the org WABA
- connect a dedicated WABA with its own `access_token`
- debug a `422` or `403` on profile creation
- make the profile completion callback idempotent

## Example prompts
- walk me through connecting the organization WABA from the Sent dashboard
- create a child profile that inherits the organization WABA
- profile creation returned 422 — what should I check first?

# WABA Onboarding and Embedded Signup

Keep three integration paths distinct. Calling all of them “Embedded Signup” creates wrong API designs and unsafe credential handling.

## The three paths

| Path | Where it starts | Profile behavior |
| --- | --- | --- |
| Organization Embedded Signup | Sent dashboard | Connects the organization's WABA through the hosted Meta flow. There is no public Sent endpoint that starts this flow. |
| Organization WABA inheritance | `POST /v3/profiles` | Omit `whatsapp_business_account`; the child inherits the organization's connected WABA. |
| Dedicated child-profile WABA | `POST /v3/profiles` | Supply `whatsapp_business_account.waba_id` and `.access_token`; `phone_number_id` is optional. |

If credentials are omitted and the organization has no connected WABA, profile creation returns `422`. Direct WABA credentials are a profile-creation feature, not a public “Embedded Signup endpoint.”

## Authentication

Use either:

- a profile-specific key in `x-api-key`; or
- an organization key in `x-api-key` plus `x-profile-id` when operating for an existing child profile.

Only organization keys may use `x-profile-id`; profile keys receive `403`. `x-sender-id` is legacy v1/v2 terminology.

## Path A: organization Embedded Signup

1. An authorized organization administrator opens the Sent dashboard WhatsApp connection flow.
2. The hosted Meta Embedded Signup UI collects the Meta authorization and WABA/number choices.
3. Confirm the organization shows a connected WABA before creating inheriting children.
4. Record non-secret identifiers and audit who completed the action.

Do not invent a `POST /embedded-signup` or token-exchange endpoint in Sent's public API. If building your own Meta Tech Provider integration outside the Sent dashboard, follow Meta's current documentation and keep that system separate from the Sent API contract.
