Integrate MSG91 into the workflow. Send SMS through approved DLT templates, send, verify and resend OTPs, send WhatsApp templates and session replies, check WhatsApp prepaid balance, and pull SMS delivery logs. Can also run workflows when MSG91 reports SMS delivery or a customer sends a WhatsApp message. Indian SMS must match a DLT-approved template exactly, so SMS and OTP always go through an MSG91 template. Requires an MSG91 authkey.
Agent Serve accounts are created by invitation. Request access for your team, or accept an invitation from your workspace admin, then sign in.
Open your workspace, drag a MSG91 block onto the workflow builder, and paste in your MSG91 API key.
Pick the tool you need, wire in an AI agent for reasoning or data transformation, and run. Your MSG91 automation is live.
8 MSG91 tools available in Agent Serve.
Send an SMS to one or many numbers through an MSG91 SMS template (Flow API), filling the template's variables. ${MSG91_DLT_NOTE}
Generate and send a one-time password by SMS with an MSG91 OTP template. MSG91 stores the code and its expiry, so check it later with Verify OTP. In India the OTP template must match a DLT-approved template exactly.
Check the OTP a user entered against the one MSG91 sent to that number. Returns verified true only on a match; a wrong or expired code returns verified false with the reason.
Resend the same OTP to a number that already got one from Send OTP, by SMS or voice call. MSG91 allows at most 2 retries.
Send an approved WhatsApp template message from your MSG91 WhatsApp number to one or many customers. Templates start a conversation; free-form replies need Send WhatsApp Message inside the 24-hour session.
Send a free-form WhatsApp text reply from your MSG91 WhatsApp number. Works only inside the 24-hour session that starts when the customer messages you; otherwise send a template.
Get the prepaid WhatsApp balance and plan status of an MSG91 WhatsApp number. Use it before a large template send to make sure the balance covers it.
Get SMS delivery logs (status, number, delivery time) for a date range, or for one send by its request ID. The range can be at most 3 days and must start within the last 3 days.
