Send Your First Message
Send a test message from your backend and understand the response.
Before You Begin
Sign in to the Smobi dashboard, select your brand, and obtain its API key. Your brand needs a configured messaging sender. If your brand is not ready to send, complete setup with your Smobi contact first.
Use a phone you control for the first test. API examples call the production API and can send real messages.
1. Store Your API Key
Keep the key in a server-side environment variable. Never place it in frontend code or commit it to Git.
export SMOBI_API_KEY='YOUR_BRAND_API_KEY'2. Send a Message
Replace the recipient with your own phone number, including its country code. Use a unique clientRef to correlate this message with your application.
curl --request POST 'https://api.smobi.com/v1/message' \
--header "x-api-key: $SMOBI_API_KEY" \
--header 'Content-Type: application/json' \
--data '{
"clientRef": "quickstart-001",
"recipientPhoneNumber": "15552223333",
"content": {
"sms": { "content": "Hello from Smobi!" }
}
}'3. Save the Message Identifier
A successful request returns HTTP 201 with smobiMessageId and status. Store the identifier alongside your clientRef. An accepted request is not proof that the phone received the message: sending and delivery happen asynchronously.
Configure a status webhook to track SENT, DELIVERED, READ where supported, or FAILED.
Next Steps
- Add RCS content and an SMS fallback.
- Sync contacts and record marketing consent.
- Use the TypeScript SDK.
If a request fails, use the troubleshooting guide. Before retrying a send after a timeout, check whether the original request was accepted to avoid sending a duplicate message.
