Asana APIConnect Asana without building on its API
Asana has a REST API. Self-serve for any Asana user, including free-tier domains (which get lower rate limits). If you're reading the docs because you need Asana 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 Asana and your other tools.

Building on the Asana API vs. having Caddi run it
| The job | Build it on the API | With Caddi |
|---|---|---|
| Getting access | Register an app, get Asana credentials, and manage tokens and refreshes. | Connect your Asana 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 Asana 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 Asana work off someone's desk, the build is the slow part.
What teams usually want the Asana API for
Email-to-task
Caddi reads inbound work-request emails, creates the matching Asana task with the right project and owner, and replies with a confirmation.
CRM-driven onboarding project
When a new account closes in the CRM, Caddi spins up the onboarding Asana project from a template and assigns the standard tasks.
Task completion write-back
When an Asana task closes, Caddi updates the upstream system of record (CRM, matter system) and notifies the requester.
Asana API questions
Does Asana have an API?
Yes. Asana has a REST API, authenticated with OAuth 2.0 or personal access token. The official documentation is at https://developers.asana.com/docs.
How do I get access to the Asana API?
Self-serve for any Asana user, including free-tier domains (which get lower rate limits).
Does the Asana API have rate limits?
150 requests/min on free domains and 1,500/min on paid domains, with max 50 concurrent GETs and 15 concurrent writes.
Can I connect Asana to my other tools without writing code against its API?
Yes. With Caddi you show the Asana task once, the way you'd train a new hire, and Caddi builds it as verified code that runs across Asana 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 Asana with Caddi?
No. There is no integration code for you to write or maintain. Every automation Caddi builds for Asana is reviewed before it runs in production, and every run is logged.
