How to Create and Send an RCS Message in a One-on-One Conversation
Once your RCS channel is active, you can start individual conversations just like you would on WhatsApp. This article walks you through opening a chat and building each type of RCS message.
Step 1: Open the Conversation
Go to Chats.
Click New, then select New Chat.
Enter the customer's phone number, including the country code (for example, +91 for India).
Under Send message via, select your RCS channel. If another channel is already selected, click Change and choose RCS.
Click Start Chat.
The conversation opens exactly like a WhatsApp chat.
Step 2: Choose Your Message Type
Inside the conversation, click the Attachment (paperclip) icon to choose the type of content you'd like to send. RCS supports three message types.
Rich Card
A Rich Card combines media, text, and interactive buttons into a single card. Best for highlighting one product, offer, or announcement with a clear call-to-action button.
Each Rich Card includes:
Optional image, video, or PDF
Card orientation (Vertical or Horizontal)
Title (up to 200 characters)
Description (up to 2000 characters)
Up to 4 buttons
Media limits: images up to 5 MB (JPEG/PNG), videos up to 16 MB (MP4), and PDFs up to 100 MB.
Carousel
A Carousel displays multiple Rich Cards that customers can swipe through. Best for showcasing several products or options that customers can browse.
When building a Carousel, you can:
Choose Small or Medium card width
Add 2 to 10 cards
Configure each card with optional media, a title, a description.

Step 3: Add Buttons (Rich Card and Carousel only)
Rich Cards and Carousel cards support several interactive button types. Each one gives your customer a different way to respond or take action.
Quick Reply — The customer taps to send a predefined reply. Required: Button Label (maximum 25 characters).
Open URL — Opens a website. Required: Button Label, Destination URL. Optional: Open inside WebView.
Dial Number — Starts a phone call. Required: Button Label, Phone Number.
View Location — Opens a map showing a predefined location. Required: Button Label, Latitude, Longitude.

Step 4: Send the Message
Once your message is ready, send it just like any other chat message.
Note: RCS only works on Android devices with RCS enabled. If the recipient is using an iPhone or has RCS disabled, the message cannot be delivered, and you'll see this error: "RCS is not supported on the recipient's device. This typically happens when the user is on an iPhone or has RCS disabled on their Android device."
