Send iMessages with Java

The short answer

Yes, Java can send iMessages. The Blue Reacher API is plain HTTPS with a bearer key, so the built-in java.net.http client sends a blue-bubble text from your dedicated line with no dependencies, and any servlet or Spring endpoint receives replies and delivery states. No SDK to install, no A2P registration required, unlimited iMessages per line. Lines pace at 50 opted-in / 30 cold new contacts a day; replies never metered.

iMessage

Hi Alex, following up on your demo request. Worth a quick chat this week?

Sent from your Java workflow

Yeah, tomorrow works.

Key takeaways

  • Java has shipped a capable HTTP client since Java 11, so the send needs no library at all: build the request, attach the bearer key, post the JSON.
  • Webhooks carry the inbound side: register your HTTPS endpoint once and every reply, delivery state and STOP opt-out arrives as a signed JSON envelope.
  • Pricing is flat: $249 per line per month with unlimited iMessages (50 opted-in / 30 cold new contacts a day) and no per-message metering, so batch jobs never surprise the bill.

How a message falls back

How a message falls backEvery message is attempted as iMessage first, falls back to RCS if the number cannot receive iMessage, and falls back to SMS if it cannot receive RCS, so the message arrives either way.iMessageBlue bubble, read in minutesRCSIf the number is Android and RCS-...SMSIf neither, so it still arrives

How do you send an iMessage from Java?

Java has shipped a capable HTTP client since Java 11, so the send needs no library at all: build the request, attach the bearer key, post the JSON.

import java.net.URI;
import java.net.http.*;

var client = HttpClient.newHttpClient();
var body = """
    {"to": "+15551234567",
     "message": "Hi Alex, worth a quick chat this week?"}
    """;

var request = HttpRequest.newBuilder()
    .uri(URI.create("https://api.bluereacher.com/v1/messages"))
    .header("Authorization", "Bearer " + System.getenv("BLUEREACHER_API_KEY"))
    .header("Content-Type", "application/json")
    .POST(HttpRequest.BodyPublishers.ofString(body))
    .build();

var response = client.send(request, HttpResponse.BodyHandlers.ofString());
  • The response carries a message id. Poll https://api.bluereacher.com/v1/status/{message_id} for pending, sent or failed, or let the webhook push delivery events to your endpoint.

How does Java receive replies and delivery states?

Webhooks carry the inbound side: register your HTTPS endpoint once and every reply, delivery state and STOP opt-out arrives as a signed JSON envelope.

  • Verification is javax.crypto in four lines: compute the sha256 HMAC of the raw request body with your webhook secret, hex-encode it, prefix sha256=, and compare it to the X-BlueReacher-Signature header.
  • A Spring @PostMapping or a plain servlet both work; the event name in the envelope routes the payload, and message.received carries the reply your code answers.

What do Java teams pay to run this?

Pricing is flat: $249 per line per month with unlimited iMessages (50 opted-in / 30 cold new contacts a day) and no per-message metering, so batch jobs never surprise the bill.

  • $1,949 per line per year comes to about $162.50 a month with the $449 activation waived. No A2P registration required, so nothing sits between the build and the first real send.
  • White-glove onboarding covers the line, the API key and the webhook registration, and a brk_test_ sandbox key runs the whole flow with nothing real sent.

Frequently asked questions

Is there a Java SDK for iMessage?

No SDK is needed. The Blue Reacher API is standard HTTPS with JSON and bearer auth, so java.net.http covers it: one POST to send, one GET for status, one endpoint for replies. The OpenAPI 3.1 spec at docs.bluereacher.com generates typed clients where a team wants them.

Does this fit a Spring Boot service?

Yes. The send is a RestClient or HttpClient call, and the webhook is a @PostMapping that verifies the HMAC signature on the raw body before parsing. Nothing about the API assumes any framework.

Can a batch job send at volume from Java?

Yes, within pacing. Sends queue through the drip pipeline by default, so a batch job can submit steadily while lines pace at 50 opted-in / 30 cold new contacts a day. Replies and delivery states stream back per message; replies are never metered.

Do I need A2P registration to text from Java?

No A2P registration required: no brand vetting, no campaign approval, no carrier queue. Messages leave a dedicated iMessage line with automatic RCS then SMS fallback for contacts who cannot receive iMessage.

What does the API cost?

$249 per line per month, unlimited iMessages, or $1,949 per year (about $162.50/month, $449 activation waived). Lines pace at 50 opted-in / 30 cold new contacts a day; replies never metered. API, MCP server and webhooks are all included.
