PUT /events/:event_id

This call is used to update an event that already exists in the evvnt system.

Event data should be sent in the the PUT body as a JSON packet with the same format as the POST /events request.

A successful PUT where the event is updated in the system will return a 200 response code.

A 404 will be returned if the event is not found in the system, or the ID of the event requested does not belong to the user associated with the API_KEY.

Values omitted from the PUT request will leave the existing value unchanged, so only pass values you want to update.

An example of a PUT request is as follows:

      curl -X PUT -H "Content-Type: application/json" -H "Accept: application/json" -u API_KEY:API_SECRET -d '{
        "title": "The Updated Event Title",
        "start_time": "2013-06-23T22:30:00+0100",
        "image_urls" : ["http://example.com/the_url_of_the_updated_image_associated_with_the_event"],
      }' https://api.evvnt.com/events/12345

GET /events/mine

This call is almost identical to GET /events (including all the same filters) except it will only return events created by the user associated with the API_KEY.

An example return packet with a single event looks like this:

      curl -X GET -H "Accept: application/json" -u API_KEY:API_SECRET https://api.evvnt.com/events/mine?some_filters...

evvnt Partner API

This API is a non-public API intended only for partners who will be creating evvnt accounts and events on behalf of their users.

You should only use this API if you are using our white label service.

It is an extension of the publisher and event organiser APIs, so that documentation remains valid, except for differences mentioned here.

The Partner API currently supports the following endpoints:

GET /contract

This call gets the API-relevant details of the contract agreed between yourself and evvnt.

      {
        "package_options": [
          {
            "id": 50
            "type": "SinglePackage"
            "broadcast_volume": 60,
            "currency": "GBP",
            "cost_per_event": "500.0"
          }
        ]
      }

GET /v3/publishers

      }' https://api.evvnt.com/users/550e8400-e29b-41d4-a716-446655440000

POST /packages

This request is used to create a package on behalf of a user created by POST /users.

This is the same as the event organiser API request, except a URL query parameter for the user who the package is being created on behalf of must be appended to the URL. For example:

      POST https://api.evvnt.com/packages?user_id=550e8400-e29b-41d4-a716-446655440000

Package data should be sent in the the POST body as a JSON packet with the following parameters:

A successful POST where the package is created will return a 200 response code and the id of the created package. e.g.

      {"id": "550e8400-e29b-41d4-a716-446655440000"}

If invalid or missing values are supplied, a 400 response code will be returned with an array of the relevant error messages in the response body.

An example of such an error response is as follows:

      {
        "errors": [
          "Package event_quantity can't be blank, is not a number"
        ]
      }

If a valid used ID is not passed, a 403 response code will be returned with an array of the relevant error messages in the response body.

An example of such an error response is as follows:

      {
        "errors" : [
          "Unknown user id"
        ]
      }

An example of a POST request is as follows

      curl -X POST -H "Content-Type: application/json" -H "Accept: application/json" -u API_KEY:API_SECRET -d '{
        "id": 50,
        "event_quantity": 5,
        "purchase_order_id": "PO235",
        "notes": ""
      }' https://api.evvnt.com/packages?user_id=550e8400-e29b-41d4-a716-446655440000

GET /users/:user_id/packages

This call lists all of the packages belonging to a specified user created by POST /users

An example return packet looks like this:

      curl -X GET -H "Accept: application/json" -u API_KEY:API_SECRET https://api.evvnt.com/users/550e8400-e29b-41d4-a716-446655440000/packages
      [
        {
          "uuid": "550e8400-e29b-41d4-a716-446655440000",
          "type": "SinglePackage",
          "broadcast_volume": 60,
          "event_quantity": 5,
          "purchase_order_id": "PO235",
          "notes": "",
          "purchase_date": "2014-01-01",
          "user_id": "550e8400-e29b-41d4-a716-446655440000"
        }
      ]

POST /events

This request is used to create an event on behalf of a user created by POST /users.

This is the same as the Event Organiser API request, except a URL query parameter for the user who the event is being created on behalf of must be appended to the URL. For example:

      POST https://api.evvnt.com/events?user_id=550e8400-e29b-41d4-a716-446655440000

The originating publisher site of the event can be specified by passing an optional query parameter "publisher_id" set to the unique ID of the publisher. For example:

      POST https://api.evvnt.com/events?user_id=550e8400-e29b-41d4-a716-446655440000&publisher_id=123456

In almost all cases a package ID should also be passed with the event, allowing us to join the user, related package and event together. (see POST /packages) For example:

      POST https://api.evvnt.com/events?user_id=550e8400-e29b-41d4-a716-446655440000&publisher_id=123456&package_id=550e8400-e29b-41d4-a716-446655440000

Event data should be sent in the the POST body as a JSON packet with the following parameters:

A successful POST where the event is created in the system will return a 200 response code and the id of the created event. e.g.

      {"id": 12345}

If invalid or missing values are supplied, a 400 response code will be returned with an array of the relevant error messages in the response body.

An example of such an error response is as follows:

      {
        "errors" : [
          "Event title can't be blank",
          "Venue name can't be blank"
        ]
      }

If a valid used ID is not passed, a 403 response code will be returned with an array of the relevant error messages in the response body.

An example of such an error response is as follows:

      {
        "errors" : [
          "Unknown user id"
        ]
      }

An example of a POST request is as follows

PUT /events/:event_id

This call is used to update an event that already exists in the evvnt system.

This is the same as the event organiser API request, except a URL query parameter for the user who the event is being created on behalf of must be appended to the URL. e.g.:

      PUT https://api.evvnt.com/events/12345?user_id=550e8400-e29b-41d4-a716-446655440000

Event data should be sent in the the PUT body as a JSON packet with the same format as the POST /events request.

A successful PUT where the event is updated in the system will return a 200 response code.

A 404 will be returned if the event is not found in the system, or the ID of the event requested does not belong to the user associated with the API_KEY.

If a valid used ID for that event is not passed, a 403 response code will be returned with an array of the relevant error messages in the response body.

An example of such an error response is as follows:

      {
        "errors" : [
          "Incorrect user id"
        ]
      }

Values omitted from the PUT request will leave the existing value unchanged, so only pass values you want to update.

An example of a PUT request is as follows:

      curl -X PUT -H "Content-Type: application/json" -H "Accept: application/json" -u API_KEY:API_SECRET -d '{
        "title": "The Updated Event Title",

GET /events/ours

This call is almost identical to GET /events from the public API (including all the same filters) except it will only return events associated users created by your API key. You can also filter by a specific user id.

Examples:

      GET https://api.evvnt.com/events/ours

      GET https://api.evvnt.com/events/ours?user_id=550e8400-e29b-41d4-a716-446655440000

An example return packet with a single event looks like this:

      curl -X GET -H "Accept: application/json" -u API_KEY:API_SECRET https://api.evvnt.com/events/ours?some_filters...
