The terms the docs and the API use, defined once. The ones people mix up most: a **workspace** is your whole tenant, a **connection** is a WhatsApp Business Account and its numbers inside it, and a **platform customer** is a reseller's end customer — each with their own isolated workspace. ### Add-on Extra capacity bought on top of a [plan](#plan): an extra member or an extra number, each billed monthly or yearly with the plan. See [Plans and limits](https://docs.lazyapp.in/billing/pricing-and-tiers.md). ### API key Your bearer credential (`Authorization: Bearer …`). Prefix `sk_test_` or `sk_live_` selects the [mode](#mode). Keys carry [scopes](https://docs.lazyapp.in/reference/scopes.md) and optional phone-number / IP restrictions — see [Authentication](https://docs.lazyapp.in/authentication.md). ### Automation pack A named bundle of starter templates and workflow defaults a platform can provision for a [platform customer](#platform-customer) at setup time. See [Automation packs](https://docs.lazyapp.in/sending/automation-packs.md). ### Broadcast A one-to-many outbound campaign paced to Meta's messaging-limit tier rather than fired all at once. See [Broadcasts](https://docs.lazyapp.in/sending/broadcasts.md). ### BSUID Business-scoped user id — Meta's opaque recipient identifier when a phone number is not available. Address it with `recipient: { "type": "bsuid", "value": "…" }` on send. See [Messages](https://docs.lazyapp.in/sending/messages.md). ### Capability A feature flag for a [connection](#connection) (calling, block lists, flows, and so on). Ask [`GET /v1/capabilities`](https://docs.lazyapp.in/concepts/capabilities) instead of hard-coding what a number supports. ### Connection One WhatsApp Business Account and its phone numbers in a [workspace](#workspace). Credentials live here. Select it with `phone_number_id` or `connection_uuid` when you have more than one. See [Workspaces and modes](https://docs.lazyapp.in/concepts/workspaces-and-modes.md) and [Connecting WhatsApp](https://docs.lazyapp.in/guides/connecting-whatsapp.md). ### Contact The person being messaged — never "user" (a user is someone who logs into LazyApp). Identified by phone, [BSUID](#bsuid), or your own external id. ### Conversation The thread between a [connection](#connection) and a [contact](#contact). Inbox and some webhooks key off `conversation_id`. ### Customer service window The 24-hour period after a contact's last inbound message during which free-form (non-template) messages are allowed. Outside it, only an approved [template](#template) will send. Reported as `service_window` on the contact. ### Embedded Signup Meta's hosted flow that connects a WhatsApp Business Account into LazyApp without you collecting tokens by hand. Platforms often wrap it in a [setup link](#setup-link). See [Connecting WhatsApp](https://docs.lazyapp.in/guides/connecting-whatsapp.md). ### Event (application event) A business signal you POST to `/v1/events` (order shipped, appointment reminder) that LazyApp can map to a template send. Distinct from a [webhook](#webhook) event LazyApp delivers to you. ### Idempotency-Key Optional header on every write under `/v1`. Retrying the same key with the same body replays the original response instead of double-sending. Messages also accept a body `idempotency_key` for permanent dedupe. See [Idempotency](https://docs.lazyapp.in/concepts/idempotency.md). ### Media A file uploaded to Meta through LazyApp (`POST /v1/media` or `/v1/media/url`) and referenced by `media_id` when sending. Meta's copy expires in about 30 days; `retention` controls whether LazyApp keeps a copy. See [Media](https://docs.lazyapp.in/sending/media.md). ### Message One outbound or inbound WhatsApp message. Status moves `queued → sent → delivered → read` / `played`, or `failed`. Schedule with `send_at`. See [Message lifecycle](https://docs.lazyapp.in/concepts/message-lifecycle.md). ### Mode `live` or `test` — never "environment". Taken from the API key prefix. Data never crosses modes. See [Workspaces and modes](https://docs.lazyapp.in/concepts/workspaces-and-modes.md). ### phone\_number\_id Meta's id for a specific WhatsApp Business phone number on a [connection](#connection). Pass it on send when the workspace has more than one number. ### Plan The flat monthly subscription (Starter, Growth or Pro) that pays LazyApp. It sets how many numbers and members a workspace has, its live broadcast sends a month, and which features it gets; live API keys and webhooks need Pro. LazyApp adds 0% to Meta's message rates: Meta bills messages to the business directly. [Test mode](#mode) is free and never plan-limited. A live key below Pro gets `402` `plan_limit_reached`. See [Plans and limits](https://docs.lazyapp.in/billing/pricing-and-tiers.md). ### Platform A LazyApp workspace for a platform team: it owns [platform customers](#platform-customer), issues setup links, and can act on a customer's behalf with `X-LazyApp-Customer`. See [Build a platform](https://docs.lazyapp.in/platform/overview.md). ### Platform customer Your customer when you resell LazyApp. Each gets an isolated [workspace](#workspace) with its own connections, keys and data. Identified by `public_id` (`cus_…`), `uuid`, or your `external_id`. ### Quality rating Meta's `GREEN` / `YELLOW` / `RED` signal for a number, exposed on [capabilities](https://docs.lazyapp.in/concepts/capabilities.md). Sliding to `RED` can cut the messaging-limit tier. ### Request id (`X-Request-Id`) Correlation id on every `/v1` response. Echo your own or accept LazyApp's. For support tickets, not for idempotency — use [`Idempotency-Key`](#idempotency-key). ### Reseller (brand) A partner who offers LazyApp under their own brand, on their own host. Each client signs up on that host and gets their own [workspace](#workspace); the reseller pays LazyApp's [plan](#plan) price for each client from the reseller's [wallet](#wallet) and bills clients however they like, outside LazyApp. Distinct from a [platform](#platform), which integrates through the API. See [Resellers](https://docs.lazyapp.in/platform/resellers.md). ### Scope A permission on an [API key](#api-key) such as `messages:send` or `webhooks:write`. A call outside the key's scopes returns `403`. See [Scopes](https://docs.lazyapp.in/reference/scopes.md). ### Setup link A one-time URL (`set_…`) a platform sends so a [platform customer](#platform-customer) can connect WhatsApp themselves. See [Setup links](https://docs.lazyapp.in/platform/setup-links.md). ### Template An approved WhatsApp message template (utility, marketing, or authentication). Required outside the [customer service window](#customer-service-window). See [Templates](https://docs.lazyapp.in/sending/templates.md). ### User Someone who signs into the LazyApp console. Not a [contact](#contact). ### Verify LazyApp's OTP send/check API for phone verification flows. See [Verify](https://docs.lazyapp.in/sending/verify.md). ### WABA WhatsApp Business Account — Meta's container for your business numbers. LazyApp stores it as part of a [connection](#connection). Meta bills messages to the WABA's own payment method at Meta's rates, and LazyApp adds 0%. See [Meta message billing](https://docs.lazyapp.in/billing/meta-message-billing.md) and [WhatsApp message rates](https://docs.lazyapp.in/billing/whatsapp-rates.md). ### Wallet Prepaid INR balance, topped up by card with **Add money**. Only two kinds of account have one: a [reseller](#reseller-brand), whose wallet pays LazyApp's plan price for each client workspace, and a [platform](#platform) team, whose wallet pays the monthly charge per connected customer number (and Meta's charges, when LazyApp pays Meta for a number). An ordinary workspace has no wallet: its [plan](#plan) is billed to a card, and Meta bills its messages directly. See [Wallets](https://docs.lazyapp.in/billing/wallets.md). ### Webhook An HTTPS endpoint you register that receives events (`message.received`, `message.delivered`, …). Delivery is at-least-once — dedupe on the event id — and signed with `X-LazyApp-Signature`. See [Webhooks](https://docs.lazyapp.in/webhooks/overview.md). ### Workflow An automation graph that reacts to inbound messages, statuses, or schedules and can send replies. Distinct from a one-shot [broadcast](#broadcast). ### Workspace Your LazyApp tenant: billing, members, connections, contacts, messages, templates, media, and webhooks. You never pass a workspace id — the API key scopes every request. Contains [modes](#mode) and [connections](#connection). When you are a [platform](#platform), each [platform customer](#platform-customer) is also a workspace.
