Zendesk APIConnect Zendesk without building on its API
Zendesk has a REST API. Self-serve for Zendesk customers on any plan, with rate limits set by plan; apps distributed to other Zendesk accounts need global OAuth. If you're reading the docs because you need Zendesk 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 Zendesk and your other tools.

Building on the Zendesk API vs. having Caddi run it
| The job | Build it on the API | With Caddi |
|---|---|---|
| Getting access | Register an app, get Zendesk credentials, and manage tokens and refreshes. | Connect your Zendesk 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 Zendesk 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 Zendesk work off someone's desk, the build is the slow part.
What teams usually want the Zendesk API for
Email-to-ticket triage
Caddi reads inbound email, classifies and routes the right Zendesk ticket, and confirms back to the customer.
CRM-to-ticket link
Caddi opens the matching Zendesk ticket from a CRM event and writes resolution back to the deal or contact when the ticket closes.
Escalation routing
Caddi watches for high-priority tickets, escalates to the right team in Slack or Teams, and tracks resolution.
Zendesk API questions
Does Zendesk have an API?
Yes. Zendesk has a REST API, authenticated with OAuth 2.0 access tokens (recommended); API tokens with basic auth are deprecated. The official documentation is at https://developer.zendesk.com/api-reference/.
How do I get access to the Zendesk API?
Self-serve for Zendesk customers on any plan, with rate limits set by plan; apps distributed to other Zendesk accounts need global OAuth.
Does the Zendesk API have rate limits?
Support API allows 200 req/min on Team, 400 on Professional, 700 on Enterprise, and 2,500 with the High Volume API add-on.
Can I connect Zendesk to my other tools without writing code against its API?
Yes. With Caddi you show the Zendesk task once, the way you'd train a new hire, and Caddi builds it as verified code that runs across Zendesk 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 Zendesk with Caddi?
No. There is no integration code for you to write or maintain. Every automation Caddi builds for Zendesk is reviewed before it runs in production, and every run is logged.
