API integration for Ringover
We build your Ringover connector
We link your customer record to the Ringover API to call from the customer record, pop the file on ring and log every call without a report to type.

What does the Ringover API provide and why integrate telephony with your CRM or business software?
Ringover is a French cloud telephony operator that allows calls to be made and received from any device. Its API lets your application trigger a call, read conversation history and transcripts, send an SMS, and be notified in real time of every inbound or outbound call. You integrate it so that sales or support calls are automatically logged in the CRM with full context, without the agent entering anything, and so that the client record appears the moment the phone rings.
What our clients build on the Ringover API
Screen pop on ring
The calling number is resolved against your customer base and the file opens before pickup. The agent sees the balance and the last exchange.
Call from the customer record
A button starts the call without leaving the work screen. No more number dialled by hand, so no more dialling error.
Call log without typing
Inbound, outbound, missed, voicemail: every call is written into the file history with its duration, agent and tags.
Callback queue for missed calls
Missed calls become an assigned, measured work queue, instead of a notification lost in an interface.
What it changes for your teams on the phone
Engineering in service of a measurable outcome: less time per call, a complete history, callbacks that do not drop.
Your teams no longer switch screens
The call is started and documented from the business software. Seconds saved per call multiply by the daily volume.
A customer history that is actually complete
Every call leaves a trace, even a missed one. Nobody needs to write a report for the sake of it.
Callbacks assigned, not hoped for
A missed call creates a task with an owner and a deadline. The callback is measured, instead of depending on goodwill.
Opposition held by the system
The opposition list lives in your database and is pushed to Ringover. Consent can be proven, which has become an obligation.
How we ship your Ringover connector
Scoping
Which flows, which users, which key permissions, what volume of history to backfill. We list the edge cases before coding.
Development
Typed connector, token bucket at two requests per second, call deduplication, retry queue, secrets isolated. A demo every week.
Testing
Replay on your real calls, webhook signature verification, test of transfers and IVR routing.
Monitoring
Alerts on 429s and on webhook failure, connector health dashboard, inspectable dead letter queue.
What the Ringover API allows
- Click-to-call and call control
- Triggering a call to an international number, with a choice of device, then hold, transfer, recording or hang-up.
- History and live calls
- Reading calls on a sliding window, live calls, tags and conferences, to feed a customer file.
- SMS, conversations and WhatsApp
- Sending SMS from the business software, related conversations and messages, plus approved WhatsApp Business templates.
- Empower transcriptions and summaries
- Call transcription, summaries and key moments, usable to prefill a report that the agent validates instead of typing.
The vocabulary of the Ringover API
- Monitoring flag
- A setting that adds no permission but widens the scope of existing permissions, from my data to that of the whole team. Without it, some routes answer 401 with no other explanation.
- device
- A three-character code that designates the device to ring: APP, WEB, SIP, MOB, EXT or ALL. It is what decides where the click-to-call goes, and it is chosen per user.
- call_id
- A call identifier that is not unique: in a transfer or IVR routing, several items in the list share it. A naive primary key on it corrupts the data.
- signing_key
- Webhook signing secret, read-only and shared by all subscriptions of a configuration. Comparing a received header to this raw key is not a valid verification.
- 402
- A response that means a feature is missing from your plan, or SMS credit is insufficient. It is a business state to handle in the journey, not a network incident to retry in a loop.
- ivr_id
- IVR identifier offset by 10,000 in webhook bodies, for historical reasons. A 22000 on the interface therefore comes back as 12000 on the event.
The real constraints of the Ringover API
Two requests per second per API key
This is the most structural point of the integration: beyond it, the API answers 429. A history backfill is split into 15-day windows and scheduled with a token bucket, never in a loop.
call_id is not a primary key
In a transfer or IVR routing, several rows share the same call identifier. Deduplication uses a composite key, otherwise the history corrupts in silence.
Permissions have two dimensions
Seven categories declined as read or write, plus a Monitoring flag that widens scope without granting a right. Contacts stay limited to the key holder's address book, even with Monitoring.
A webhook URL is immutable
Changing URL means creating a subscription then deleting the old one, and a subscription on an already known URL merges the event sets. Two signature versions coexist, both to be handled.
Ringover or Twilio for telephony?
A French operator with its handsets and supervision on one side, a programmable platform on the other. The right one depends on who is on the phone.
| Criterion | RingoverThis page | TwilioProgrammable operator |
|---|---|---|
| Target case | Equip agents who make calls | Make your application place calls |
| Handsets and interface | Provided, with supervision | To be built |
| Vendor | France | United States |
| API throughput | 2 requests per second per key | 10 segments/s with an alpha sender |
| Webhook signature | JWT HS512 or HMAC-SHA256 | X-Twilio-Signature in HMAC-SHA1 |
| Call summary | Empower: transcription and summary | To assemble with a third-party model |
| The right case | Teams wired into the business | Notifications, OTP and programmable voice |
The two combine: Ringover for teams who make calls, Twilio for automated outbound flows. This is a scoping arbitration, not a final choice.

Ringover integration: your questions
Three steps. Create an API key per use, with the minimal permission scope and the Monitoring flag enabled only where a route requires it. Build a connector that respects two requests per second with a token bucket and a persistent queue, and that deduplicates calls on a composite key, since the call identifier is not unique. Then expose a webhook endpoint that verifies the signature, answers fast and processes asynchronously. The sensitive part is not the API call, it is throughput and history deduplication.
A first useful flow, typically click-to-call from the customer record and the call log, ships in two to three weeks. A full chain with screen pop, callback queue, follow-up SMS and call summaries takes closer to six to eight weeks. History backfill often weighs more than real time, because of the 15-day window and the limited throughput. We scope the perimeter up front and give a firm estimate before starting.
Through call webhooks. Ringover pushes the ringing event to your application, which resolves the calling number against your customer base and opens the file before pickup. Three precautions matter. Verify the webhook signature, implementing the version your team is configured for, knowing the recent version has a fixed size while the older one grows with the payload. Deduplicate events, since the same event can be redelivered. And plan for an unknown or withheld number, which should open a creation screen rather than an error.
Technically yes: the API exposes call campaigns with number lists, scripts, tags and a maximum number of attempts. Legally, the framework has changed. Since 11 August 2026, telephone canvassing without the consumer's prior consent is prohibited, the Bloctel scheme has disappeared, proof of consent sits with the professional and a contract concluded after unconsented canvassing is void. We therefore build this kind of feature around a timestamped consent register and an opposition list pushed to Ringover, consulted before every call.
Ringover equips humans who make calls: handsets, supervision, queues and interface are provided, and the API is used to graft that telephony onto your business software. Twilio makes an application place calls: everything is programmable, but the agent interface is yours to build. If your need is a call centre wired into the business, with screen pop and an automatic log, Ringover is the right choice, with a French vendor for the contractual relationship as well. If your need is an automatic call triggered by a product event, that is Twilio.
