RCS Business Messaging API Provider in Hyderabad
For development teams connecting a CRM or ERP to RCS. RCS Message.in is run by 1by0 Solutions from Hyderabad; this page shows how a send and its delivery reports fit together, and what to prepare before you talk to us.
Illustrative workflow
From a CRM event to a reconciled delivery report
The message ID is what ties a send to its delivery reports. Store it as soon as a request is accepted.
1. Your CRM triggers a send
An event in your CRM or ERP, such as a confirmed order or a booked appointment, asks your integration to send an approved template with that customer's values.
2. The API accepts the request
When the request is accepted, store the message ID it returns against your own send attempt: your record ID, template, recipient and time.
3. Delivery reports arrive on your webhook
Each report carries the message ID. Use it to find the send attempt and update its status.
4. Your CRM shows the outcome
Staff and reports see delivered, failed or still pending for each customer record, from your own data.
Reconciling reports
What each outcome means for your records
Accepted is not delivered
Acceptance means the platform will try to deliver the message. Record it as accepted, then wait for a delivery report.
Delivered doesn't guarantee a read receipt
Read status is reported by the recipient's device. A delivered message with no read status may still have been read.
A timeout leaves the outcome unknown
If your request times out, you don't know whether it was accepted. Mark the attempt as unknown and check before sending again, so the customer doesn't get the message twice.
Callbacks can repeat or arrive out of order
Record each status once per message ID, ignore repeats, and never let an older status overwrite a newer one, such as pending arriving after delivered.
The delivery reports guide explains each status, and the RCS API integration guide in PHP shows idempotent webhook handling with illustrative code.
Before you enquire
Developer preparation checklist
Sending system
Which CRM, ERP, app or website will send messages, and what event should trigger each one.
Template variables
The values each message needs, such as name, order number or appointment time, and where they come from.
Expected volume
Roughly how many messages per day or month, and whether sends come in bursts.
Message category and timing
Whether each trigger sends transactional or promotional messages. Transactional RCS messages can be sent 24×7. Promotional RCS messages can be sent between 7:00 AM and 10:00 PM IST. Promotional RCS messages submitted outside this window are rejected, and their credits are returned to your account. These are sending hours. Actual delivery depends on recipient availability, device/network support and provider processing.
Webhook endpoint
A public HTTPS endpoint you control that can accept POST requests for delivery reports.
Reporting needs
Which statuses your team needs to see, where, and how long you keep them.
Never put passwords, API keys, tokens or customer data in the enquiry form. Credentials are issued privately after onboarding.
