Ramp APIConnect Ramp without building on its API
Ramp has a REST API. Self-serve for Ramp customers with dashboard admin access; partners building integrations go through Ramp's partner integration program. If you're reading the docs because you need Ramp 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 Ramp and your other tools.

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

Ramp API questions
Does Ramp have an API?
Yes. Ramp has a REST API, authenticated with OAuth 2.0 (client credentials or authorization code, with scopes). The official documentation is at https://docs.ramp.com/developer-api/v1.
How do I get access to the Ramp API?
Self-serve for Ramp customers with dashboard admin access; partners building integrations go through Ramp's partner integration program.
Does the Ramp API have rate limits?
200 requests per 10-second rolling window per source IP, and requests over 60 seconds time out.
Can I connect Ramp to my other tools without writing code against its API?
Yes. With Caddi you show the Ramp task once, the way you'd train a new hire, and Caddi builds it as verified code that runs across Ramp 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 Ramp with Caddi?
No. There is no integration code for you to write or maintain. Every automation Caddi builds for Ramp is reviewed before it runs in production, and every run is logged.
