In plain language
GET reads, POST creates or triggers, PUT and PATCH update, and DELETE removes.
Example
A workflow uses PATCH to change only a deal’s stage, without resending every other field.

Common misconception
PUT and PATCH are not interchangeable; PUT usually replaces the whole resource, while PATCH changes only the fields sent.
Implementation guidance
Use the method the API documents for each endpoint, avoid side effects in GET requests, and remember that POST retries can create duplicates.
