Add / Update Funding Project

Add or update a project.

The project to be updated should be stored as a JSON-serialised document in the request data. We will attempt to update any project with the same project_id: if none is found we assume it's a new project.

You can use the get project by UUID call to check the posted project.

Resource URL

POST https://crowdsurfer.com/api/1.0/project/

Return

Success

HTTP 200: OK

Returns with a status code of 200 and the UUID of the project in a JSON dictionary e.g:

{"uuid": "b4df7b093b9b33fbbc11be54bf8355cb"}

Failure

HTTP 401: bad request

Indicates that the project document is malformed. The response content will contain a JSON document with a key "detail" which will itself contain a dictionary describing each field error. For example:

{ "detail" : { "funding_type": u"Invalid funding type code XX: please select one from ME, MD, C, MF, E, D, RS, ML, DE, L, O, IV, R, IN, Y" } }

HTTP 403: permisson denied

Indicates that an attempt was made to add or update a project for a platform that you don't have permission to update. Check that you are using the correct platform_id.

Example

The following example inserts a single rewards funding project for platform Kickstarter.

Add / Update Funding Project

:

Using the standard curl command:

curl -X POST \ -H "Accept: application/json" \ -H "Content-Type: application/json" \ -H "Authorization: Token abcdef123456890" \ -d '{ "currency": "GBP", "description": "This widget will change your life!", "funding_type": "R", "goal": 10000, "language": "en", "platform_id": 443, "project_id": "12345", "raised": 500, "title": "A new widget" }' \ https://crowdsurfer.com/api/1.0/project/

We depend on the very useful requests library.

import requests import json payload = { "currency": "GBP", "description": "This widget will change your life!", "funding_type": "R", "goal": 10000, "language": "en", "platform_id": 443, "project_id": "12345", "raised": 500, "title": "A new widget" } r = requests.post('https://crowdsurfer.com/api/1.0/project/', headers={'Authorization': 'Token abcdef123456890', 'Content-Type': 'application/json'}, data = json.dumps(payload)) if r.status_code == 200: # We return the UUID field for successfully uploaded projects: print("UUID: %s" % r.json()['uuid']) else: print("Failed: errors = %r" % r.json()['detail'])

Assumes that Guzzle has been installed using Composer.

require 'vendor/autoload.php'; use GuzzleHttp\Client; use GuzzleHttp\Exception\ClientException; $client = new GuzzleHttp\Client(); try { $response = $client->post('https://crowdsurfer.com/api/1.0/project/', [ "headers" => [ "Accept" => "application/json", "Content-Type" => "application/json", "Authorization" => "Token abcdef123456890" ], "json" => [ "raised" => 500, "description" => "This widget will change your life!", "platform_id" => 443, "goal" => 10000, "funding_type" => "R", "currency" => "GBP", "language" => "en", "title" => "A new widget", "project_id" => "12345" ] ]); $json = $response->json(); /* We return the UUID field for successfully uploaded projects: */ $uuid = $json["uuid"]; var_dump($uuid); } catch (ClientException $e) { /* Failed uploads should return a "detail" dictionary describing the invalid fields: */ $errors = $json["detail"]; var_dump($errors); }

We use the Fluent API component of the Apache HttpComponents library.

Here's the Maven POM file:

4.0.0 crowdsurfer_post cspost 1.0-SNAPSHOT org.apache.httpcomponents httpclient 4.5 org.apache.httpcomponents fluent-hc 4.5

And here's the Java class. Note that unlike the other examples we assume that the project has already seen serialised as a JSON string. Obviously in production you would be mapping from your database entities into JSON (possibly using json-simple or equivalent).
