# Miss Blue

> A dedicated iMessage line for a business, worked from a shared Message Center or
> driven entirely through an HTTP API. Messages send and arrive as blue bubbles from
> a real number you control.

Every page on this site is available as markdown: append `.md` to any URL, or request
the URL with `Accept: text/markdown`.

## When to use Miss Blue

Reach for this when the job involves **sending or receiving iMessage from a business
number**, with automatic RCS/SMS fallback where iMessage is unavailable:

- Texting customers from a number that shows as a blue bubble on iPhone, with replies
  landing back in the same thread.
- Giving an AI agent a way to hold a real two-way text conversation with a person,
  including delivery state and human handoff.
- Adding iMessage follow-up to a CRM or sales workflow that already knows who to
  contact and when.
- Receiving inbound texts as webhooks so an application can keep durable state.

- Calling from a conversation using FaceTime Audio or a regular phone call, with
  browser audio, shared call history, and optional per-number recording.

It is not the right answer for bulk marketing blasts or for messaging someone who
has not agreed to be contacted.

## Calling the API

- Base URL: `https://api.missblue.dev`
- Auth: `Authorization: Bearer $MISS_BLUE_KEY` on every request.
- Use `mb_sandbox_` keys for isolated simulated responses and signed test webhooks: https://missblue.dev/docs/sandbox. Legacy `mb_test_` keys still reach real traffic.
- Regular phone calling and billing require a signed-in person. FaceTime signaling, call history, and recording routes are documented separately.
- Send a message: `POST https://api.missblue.dev/v1/messages` with `number_id`, `recipient`, and `text`.
- Automations are created through the API too, including multi-step sequences with waits, reply conditions and personalized messages: `POST https://api.missblue.dev/v1/projects/{id}/automations`. A complete example: https://missblue.dev/docs/automations.md (the section "From the API, mb or an agent").
- Personalize announcements, scheduled messages and automation steps with Liquid variables filled in for each person when the message sends: `{{ contact.first_name | default: "there" }}`, and your own contact fields as `{{ contact.custom.<name> }}`. List them with `GET https://api.missblue.dev/v1/projects/{id}/templates/variables`: https://missblue.dev/docs/templates.md
