Stripe APIIntegration guide

Integrate the Stripe API.Caddi writes and runs the integration for you.

Stripe has a REST API. Self-serve for any developer (free account with sandbox keys).

  • 99%of agent runs complete successfully
  • ~45 minon average to build your first agent
  • 1M+back-office tasks completed
01Getting access

The connection is a project before it does anything.

Before the first record moves: an app registration, credentials, token refresh, and somewhere to host and monitor the code. Global limit of 100 requests/second in live mode and 25/second in sandbox, with most individual endpoints capped at 25 requests/second.

On your own

Register an app, store Stripe credentials, refresh tokens and code around the rate limits.

With Caddi

Connect your Stripe account once. Caddi holds the connection.

02The whole job

The job doesn't stop at Stripe.

An intake, a filing or a client update also runs through email, documents and the other systems your team works in. The Stripe API only reaches Stripe.

On your own

Each extra system is another API, another set of credentials, another integration to own.

With Caddi

One automation runs across every tool the job touches, each through its API.

03After launch

Someone has to own the code.

API versions change, fields get added and your process moves.

On your own

A developer patches and redeploys the integration each time.

With Caddi

The person who does the work updates it by showing or describing the change. Every automation is reviewed before it runs in production, and every run is logged.

When to build the Stripe integration in-house

When you have engineers and the integration is your product, or you need one narrow sync between two systems and someone to own it. When the goal is getting Stripe work off someone's desk, the build is the slow part, and Caddi does it for you.

What teams usually want the Stripe API for

  • Payment-to-books posting

    Caddi summarizes daily Stripe activity and posts the journal entries to QuickBooks or Xero with the right customer coding.

  • Failed-payment chase

    Caddi identifies failed Stripe charges, drafts the personalized outreach, and updates the CRM with the result.

  • Invoice reconciliation

    Caddi matches Stripe payments against open invoices in your billing system and writes the reconciled record back.

Everything Caddi does with Stripe.

Stripe API questions

Does Stripe have an API?

Yes. Stripe has a REST API, authenticated with API key (secret/restricted keys); OAuth for Connect platforms. The official documentation is at https://docs.stripe.com/api.

How do I get access to the Stripe API?

Self-serve for any developer (free account with sandbox keys).

Does the Stripe API have rate limits?

Global limit of 100 requests/second in live mode and 25/second in sandbox, with most individual endpoints capped at 25 requests/second.

Can I connect Stripe to my other tools without writing code against its API?

Yes. With Caddi you show the Stripe task once, the way you'd train a new hire, and Caddi builds it as verified code that runs across Stripe and the other tools the job touches. Steps that need a person's judgment are handed to Copilot or Claude, and Caddi monitors those too.

Do I need a developer to automate Stripe with Caddi?

No. There is no integration code for you to write or maintain. Every automation Caddi builds for Stripe is reviewed before it runs in production, and every run is logged.
