Zoho CRM APIConnect Zoho CRM without building on its API
Zoho CRM has a REST API. Self-serve for Zoho CRM customers on all editions, including Free, with API credits scaled by edition. If you're reading the docs because you need Zoho CRM 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 Zoho CRM and your other tools.

Building on the Zoho CRM API vs. having Caddi run it
| The job | Build it on the API | With Caddi |
|---|---|---|
| Getting access | Register an app, get Zoho CRM credentials, and manage tokens and refreshes. | Connect your Zoho CRM 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 Zoho CRM 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 Zoho CRM work off someone's desk, the build is the slow part.
What teams usually want the Zoho CRM API for

Caddi reads inbound email, identifies the contact and intent, and writes a structured activity to Zoho CRM with the right follow-up.
