# Getting Started

Requirements for API scripting:

- Access to the Admin/API TLS Connection (default port 8443) of a Controller appliance.
([https://support.appgate.com/docs/adminapi-tls-connection-v6-7](https://support.appgate.com/docs/adminapi-tls-connection-v6-7))
- An API user with relevant permissions.
([https://support.appgate.com/docs/configure-admin-roles-v6-7](https://support.appgate.com/docs/configure-admin-roles-v6-7))
- In order to use the simple login API, Admin MFA must be disabled or the API user must be excluded.
([https://support.appgate.com/docs/mfa-for-admins-v6-7](https://support.appgate.com/docs/mfa-for-admins-v6-7))

# Base path

HTTPS requests must be sent to the Admin Interface hostname and port, with **/admin** path.

For example: **[https://appgate.company.com:8443/admin](https://appgate.company.com:8443/admin)**

All requests must have the **Accept** header as:

**application/vnd.appgate.peer-v24+json**

An exception is made for the **/admin/version** endpoint which instead expects an **application/json** Accept header.

# API Conventions

API conventions are important to understand and follow strictly.

- While updating objects (via PUT), entire object must be sent with all fields.
  - For example, in order to add a remedy method to the condition below:

```
{
  "id": "12699e27-b584-464a-81ee-5b4784b6d425",
  "name": "Test",
  "notes": "Making a point",
  "tags": ["test", "tag"],
  "expression": "return true;",
  "remedyMethods": []
}
```
  - send the entire object with updated and non-updated fields:

```
{
  "id": "12699e27-b584-464a-81ee-5b4784b6d425",
  "name": "Test",
  "notes": "Making a point",
  "tags": ["test", "tag"],
  "expression": "return true;",
  "remedyMethods": [{"type": "DisplayMessage", "message": "test message"}]
}
```
- In case Controller returns an error (non-2xx HTTP status code), response body is JSON. The "message" field contains information about the error. HTTP 422 "Unprocessable Entity" has extra `errors` field to list all the issues with specific fields.
- Empty string (<cite>) is considered a different value than "null" or field being omitted from JSON. Omitting the field is recommended if no value is intended. Empty string (</cite>) will be almost always rejected as invalid value.
- There are common pattern between many objects:
  - **Configuration Objects**: There are many objects with common fields, namely "id", "name", "notes", "created"
and "updated". These entities are listed, queried, created, updated and deleted in a similar fashion.
  - **Distinguished Name**: Users and Devices are identified with what is called Distinguished Names, as used in
LDAP. The distinguished format that identifies a device and a user combination is
"CN=<Device ID>,CN=<username>,OU=<Identity Provider Name>". Some objects have the
"userDistinguishedName" field, which does not include the CN for Device ID.
This identifies a user on every device.
