Retool iMessage Integration — Add iMessage to Internal Tools
Build custom internal messaging dashboards with Retool and Sendblue. Use Retool's REST API resource to send iMessages, track deliveries, and manage conversations from your own internal tools.
How to Connect Retool + Sendblue
Create a REST API Resource
In Retool, create a new REST API resource pointing to https://api.sendblue.co. Add your Sendblue API key and secret as headers for authentication.
Build Your Send Query
Create a query that POSTs to /api/send-message with the recipient's phone number and message body. Bind these fields to input components in your Retool app.
Configure Webhooks for Replies
Set up a Sendblue inbound webhook pointing to your backend or a Retool Workflow. Incoming replies get stored in your database and displayed in your Retool app.
Key Features
Custom Messaging UI
Design the exact messaging interface your team needs. Build chat-style views, contact lists, and message templates — all within Retool's drag-and-drop builder.
Full API Access
Send messages, check delivery status, look up iMessage availability, and manage contacts. Every Sendblue API endpoint is available as a Retool query.
Database Integration
Connect your existing database to pull contact info, log conversations, and track message history. Retool queries your DB and Sendblue in the same app.
Smart Routing
Sendblue detects iMessage availability automatically. iPhone contacts get blue bubbles; others get SMS. No conditional logic needed in your Retool app.
Team Permissions
Use Retool's built-in access controls to manage who can send messages, view conversations, and modify templates. Role-based access out of the box.
Media & Attachments
Send images, PDFs, and vCards through the API. Build file upload components in Retool that attach media to outgoing iMessages.
Why Retool + iMessage?
Retool is the fastest way to build internal tools. With Sendblue's REST API, you can add iMessage capabilities to any Retool app in minutes — no custom backend required for basic messaging workflows.
Build what off-the-shelf tools can't: Most messaging platforms force you into their UI. With Retool + Sendblue, you design the exact workflow your operations team needs. A support dashboard that shows customer context alongside the messaging thread. A sales tool that pulls CRM data and sends personalized iMessages with one click. A dispatch system that texts drivers and logs responses.
The connection is straightforward: Retool's REST API resource talks directly to the Sendblue API. There's no native integration to install — you're making standard HTTP requests, which means full flexibility over request parameters, error handling, and retry logic.
Combine messaging with Sendblue's FaceTime Audio calling to build complete communication tools. Your team gets a single internal app for messaging and calling, connected to your database and business logic.

Get API AccessFrequently Asked Questions
Does Sendblue have a native Retool integration?
Sendblue does not have a native Retool integration. Instead, you connect Sendblue to Retool using Retool's built-in REST API resource. Point it at the Sendblue API endpoints and you can send messages, check delivery status, and receive webhooks — all from your custom Retool apps.
Can I build a full messaging inbox in Retool?
Yes. Use the Sendblue API to send messages and configure webhooks to receive replies. Display conversations in a Retool table or list view, and add a text input for composing new messages. You can build a complete two-way messaging dashboard.
How do I handle incoming message webhooks in Retool?
Set up a Sendblue webhook pointing to a Retool Workflow endpoint or your own backend. When a reply arrives, the webhook payload includes the sender's number, message content, and timestamp. Store these in your database and display them in Retool.
What about contacts without iMessage?
Sendblue automatically detects iMessage availability and falls back to SMS for Android users. Your Retool app doesn't need any special logic — Sendblue handles the routing automatically.
