RingCentral
Add RingCentral to your product for your customers, and give your AI agents governed access to it.
RingCentral is a cloud phone system, and its platform API covers the whole surface a business phone number touches: SMS and MMS, telephony and call control, the call log, voicemail and fax, team messaging, and the video meetings that come with RingEX. Extensions are the unit that decides whether an integration is trustworthy, because a message or a call belongs to a user's extension rather than to the account, and an integration that ignores that attributes activity to the wrong person. Events arrive through subscriptions rather than polling, and subscriptions expire, so renewal is part of the job. Rate limits are grouped by API class, so a heavy call-log read and a message send are throttled separately. fastn owns the credentials, subscription renewals and API upkeep.
In your product
Embedded for your customers. Per-tenant auth, no per-customer code, maintained by fastn.
Let each customer connect their own RingCentral account so calls and messages come from their numbers and their extensions.
Send SMS from your product on the customer's own number rather than a shared sender they cannot brand.
Read the call log per extension, so activity is attributed to the person who actually made the call.
Create a video meeting and hand the join link back, so scheduling happens where the work already is.
For your AI agents
Governed, audited access for the agents you build, through the MCP server.
An agent summarises a customer's call activity for a period, scoped to their account only.
An agent sends a message or schedules a meeting within the permissions granted, with the action attributed.
An agent checks presence before it suggests who to transfer a caller to.
Example prompt
Which calls to this customer went unanswered yesterday, and did anyone leave a voicemail?
Set up RingCentral in 4 steps
- 01Enable the RingCentral connector in your fastn dashboard.
- 02Have each customer authorise their own RingCentral account so calls and messages originate from their numbers.
- 03Map the extensions, numbers and message or call-log fields your product uses, then subscribe to the events you act on.
- 04Call it from your product and expose the same connection to your agents through the MCP gateway.
Why teams use the RingCentral integration
What you get by embedding it with fastn instead of building it yourself.
- Ship a RingCentral integration without building it. Your customers connect their own RingCentral account inside your product and work their meetings, calls and participants there, with no per-customer code on your side.
- Handle the part that actually costs time: a call or a meeting is a real-time event, so a missed join or a dropped recording cannot be retried later. fastn owns the auth, token refresh, rate limits, pagination and breaking-change fixes, so a RingCentral update is not your on-call problem.
- One integration serves your product and your agents. The same governed RingCentral connection powers in-product features and gives AI agents scoped, audited access, so you let your product act on the conversations that happen by voice and video, not just the written ones without wiring it twice.

AppointletRingCentral integration FAQ
How do I add a RingCentral integration to my product?
Enable the RingCentral connector in your fastn dashboard, then let each customer authenticate their own RingCentral account. fastn handles the OAuth flow, token storage and refresh per tenant, so there is no RingCentral client code in your app and no per-customer branch in your codebase. Setup is 4 steps.
Do my customers each connect their own RingCentral account?
Yes. Every connection is scoped to the individual customer, so each authorises their own RingCentral account and only ever sees their own meetings, calls and participants. That per-tenant isolation is the point of an embedded integration: you support the long tail of customer setups without maintaining an integration per customer.
Can AI agents use this RingCentral integration?
Yes. The same connection is exposed to your agents through the fastn MCP gateway, with permissions scoped per tenant and every call audited. An agent summarises a customer's call activity for a period, scoped to their account only.
Who maintains the RingCentral integration?
fastn does. When RingCentral changes an endpoint, deprecates a field or alters its auth, the fix lands in the connector rather than in your backlog, and your customers' connections keep working.
Can my product schedule or act on RingCentral conversations automatically?
Yes. Within the permissions each customer grants, your product can create a meeting, place or route a call, add participants, or react when one ends, all inside their own RingCentral account rather than through a shared one.
Can I get recordings, transcripts and outcomes back from RingCentral?
Yes, scoped per tenant and audited. This matters more here than in most integrations, because the substance of a call usually exists only in its recording or transcript, so a read that fails silently loses the thing you wanted.
What can I build with the RingCentral integration?
A common starting point: let each customer connect their own RingCentral account so calls and messages come from their numbers and their extensions. Teams also use it for the other use cases listed above, and expose it to agents for governed reads and writes.
How much does the RingCentral integration cost?
It is included. Pricing is based on connected accounts, not on how many connectors you enable, so adding RingCentral does not change your per-connector cost. You can start free with 3 connected accounts.
