RingCentral APIConnect RingCentral without building on its API
RingCentral has a REST API. Any developer with a RingCentral account can register an app in the Developer Console (admin permission may be required); production-graduation requirements were not verified. If you're reading the docs because you need RingCentral to talk to the rest of your stack, Caddi does that without you writing or maintaining integration code: you show it the job once, and it runs it across RingCentral and your other tools.

Building on the RingCentral API vs. having Caddi run it
| The job | Build it on the API | With Caddi |
|---|---|---|
| Getting access | Register an app, get RingCentral credentials, and manage tokens and refreshes. | Connect your RingCentral account once. Caddi holds the connection. |
| Writing the integration | A developer maps fields, handles pagination, retries and rate limits, and writes the sync. | You show Caddi the RingCentral task the way you'd train a new hire. It writes verified code for it. |
| Steps the API doesn't cover | Screens with no endpoint stay manual, or need a separate RPA tool. | Caddi uses a secure, audited browser session where there's no API, in the same automation. |
| The other systems in the loop | Each extra tool is another API, another set of credentials, another integration to own. | One automation runs across all the tools the job touches. |
| Keeping it running | Someone owns the code when the API version, fields or your process change. | Every automation is reviewed before it runs in production, and every run is logged. |
Building on the API is the right call when you have engineers and the integration is your product. When the goal is getting RingCentral work off someone's desk, the build is the slow part.
What teams usually want the RingCentral API for
Next-day client SMS
Caddi identifies next-day follow-ups from the calendar, pulls the related case record, and sends the appropriate client SMS through RingCentral.
SMS payment reminders
Caddi identifies eligible outstanding balances and sends SMS payment reminders while notifying the assigned staff member.
Call logging to CRM
After each RingCentral call, Caddi writes a structured activity to the CRM and opens any committed follow-up.
RingCentral API questions
Does RingCentral have an API?
Yes. RingCentral has a REST API, authenticated with OAuth 2.0 (3-legged authorization code or JWT grant). The official documentation is at https://developers.ringcentral.com/guide.
How do I get access to the RingCentral API?
Any developer with a RingCentral account can register an app in the Developer Console (admin permission may be required); production-graduation requirements were not verified.
Does the RingCentral API have rate limits?
Default per-user limits by group: Light 50/min, Medium 40/min, Heavy 10/min, Auth 5/min, with a 60-second penalty when exceeded.
Can I connect RingCentral to my other tools without writing code against its API?
Yes. With Caddi you show the RingCentral task once, the way you'd train a new hire, and Caddi builds it as verified code that runs across RingCentral and the other tools the job touches. Where a step has no API, Caddi uses a secure, audited browser session in the same automation.
Do I need a developer to automate RingCentral with Caddi?
No. There is no integration code for you to write or maintain. Every automation Caddi builds for RingCentral is reviewed before it runs in production, and every run is logged.
