Supported HTTP Methods

You can select from five primary HTTP methods when creating or editing a Web API:

1. GET: Used for retrieving data from Appian (e.g., querying record types or process analytics). GET methods cannot execute smart services; attempting to do so will result in an error.
2. POST: Used for sending data to Appian to create or update information, or to trigger actions. It is commonly used to start a process model or write data using smart services.
3. PUT: Used to update existing data or upload files. Like POST, it can execute smart services.
4. DELETE: Used to remove data or documents from Appian. This method can also execute smart services.
5. PATCH: Used for making partial updates to a resource. It can execute smart services to implement custom update logi
