MyCase APIConnect MyCase without building on its API
MyCase has an Open API (REST). The Open API is only available on MyCase's Advanced tier, and you request client credentials from MyCase support. MyCase doesn't support API implementations directly; it points firms to its certified consultants. If you're reading the docs because you need MyCase 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 MyCase and your other tools.

Building on the MyCase API vs. having Caddi run it
| The job | Build it on the API | With Caddi |
|---|---|---|
| Getting access | Register an app, get MyCase credentials, and manage tokens and refreshes. | Connect your MyCase 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 MyCase 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 MyCase work off someone's desk, the build is the slow part.
What teams usually want the MyCase API for
Intake to matter
Caddi reads an intake email, opens the matter in MyCase, and files the client documents.
Document sync
Caddi saves signed documents into the MyCase matter and updates the related task.
Time and billing
Caddi pushes captured time entries into MyCase and reconciles them against LawPay.
MyCase API questions
Does MyCase have an API?
Yes. MyCase has an Open API (REST), authenticated with OAuth 2.0. The official documentation is at https://mycaseapi.stoplight.io/docs/mycase-api-documentation/k5xpc4jyhkom7-getting-started.
How do I get access to the MyCase API?
The Open API is only available on MyCase's Advanced tier, and you request client credentials from MyCase support. MyCase doesn't support API implementations directly; it points firms to its certified consultants.
Does the MyCase API have rate limits?
25 requests per second per client. Access tokens last 24 hours and refresh tokens two weeks.
Can I connect MyCase to my other tools without writing code against its API?
Yes. With Caddi you show the MyCase task once, the way you'd train a new hire, and Caddi builds it as verified code that runs across MyCase 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 MyCase with Caddi?
No. There is no integration code for you to write or maintain. Every automation Caddi builds for MyCase is reviewed before it runs in production, and every run is logged.
