Manage Mocking Rules

You can manage an endpoint's mocking rules via API. These will help you build use-cases to create or update mocking rules programmatically and later send the request. Any update to mocking rules is reflected in real-time.

Rule Selection

An endpoint can have multiple mocking rules. These rules can match requests based on request's path or contents in the request's body. When a request is sent to a Beeceptor endpoint, mocking rules are evaluated in displayed order. The first rule qualifying the criteria is selected to serve the response.

Get All Rules

List all rules configured for an endpoint.

Request Details

Method	Request Path
`GET`	`https://api.beeceptor.com/api/v1/endpoints/<my-endpoint>/rules`

<my-endpoint> - name of the Beeceptor endpoint

Response Object Details

Response holds an array of found requests in data parameter. Refer a sample below.

Response parameters	Details
`id`	identifier to uniquely identifies this rule.
`enabled`	Default - `true`. Helps you turn on/off a rule to skip evaluation.
`mock`	Default - `true`. When using proxy setup, this indicates if the rule should attempt mocking. E.g. when set to false `false` mocking is not attempted and only `delay` is effective.
`description`	Optional. Description of the rule
`delay`	Indicates if this rule should respond after these mili seconds
`match.method`	During rule evaluation, filter request with this method (GET, POST, PUT, etc). This will be applied as AND with `operator`.
`match.operator`	Operator to match the incoming request. Possible values: `SW` - request path starts with `CO` - request path contains `EM` - request path exactly matches `B_CO` - request body contains
`match.value`	During rule evaluation, match the request path with this value. (`operator` is used to match against this value)
`send.status`	When the rule is matched, response HTTP status code to send.
`send.body`	When the rule is matched, response body to send.
`send.headers`	When the rule is matched, response headers to send.
`send.templated`	Optional. Enable HandlesBar templates in the mocked response. Defaults to false. Read more here

Success Response

A success response has 200 as HTTP status code.

        "templated": false
    }
}

Success Response

The following represents a success response with 200 as HTTP response code. The created rule is present in data parameter and has id field to uniquely identify this rule.

{

    "enabled": false,
    "mock": false,
    "delay": 0,
    "match": {
      "method": "GET",
      "operator": "SW",
