2. Testing API sandbox system

To test online-billing-service.com API we made a system sandbox.

It is available at: https://sandbox.online-billing-service.com
API key: 91b4e03e6d4a07c088921a07ab8e844c7508092cf1645b32657d6c4b5829
Access date:
- Login address: https://sandbox.online-billing-service.com/login
- Account name: sandbox
- User name: john.smith
- Password: j0HnsPsW!D

3. Authentication

API key is defined by user and you can generate it from your online-billing-service.com account, at “User Profile“ -> “API Key“

There are available two methods of authentication:

HTTP Authentication (you will use API key as a username, password will be ignored)
Api key parameter added on each request.

4. Results and errors

Resources are returned in xml format. Result of a request has returning a HTTP status:

200 Success (after a successful GET, PUT, or DELETE request)
201 Created (after a successful POST request)
400 Resource Invalid (wrong formatted request)
401 Unauthorized
404 Resource Not Found
405 Method Not Allowed (HTTP verb used is not accepted for this resource)
422 Unprocessable Entity (Request has a good syntax, but modifies requested are wrong)
500 Application Error (System error)

For correct syntax calls, but which do not meet the system validation criteria, the errors will be returned in the response body as:

  <errors>
  <error>Error message</error>
  <error>Another error message</error>
  ...
</errors>

After adding a record, the URL at which the new record is available will be returned in the response header `Location '.

5. Fields and data types

All models contain the following fields:

id - unique identifier of the record
created_at - hour and date of record creation
updated_at - hour and date of record update

Fields marked with (R) are read-only; computed by our sistem using other data.

Data types:

Date format is AAAA-LL-ZZ
boolean values represented with true / false
using identifiers (id) numbers

6. Writing operations

Fields marked with * are mandatory

Models aggregate The aggregate models will be specified by identifier. Example: currency_id will be specified for the currency.

The data can be sent as xml or sent as the parameters in the HTTP request. In both cases, the model name will always be specified.

When using update operations (POST), it is only necessary to send the updated fields.

6.1. Writing examples

Modify client name (xml):

  curl -H 'Content-Type: application/xml'
  -X PUT https://online-billing-service.com/api/v1/clients/1.xml -u [api_key]:x \
  -d '<?xml version="1.0" encoding="UTF-8"?>
  <client>
    <name>Client Name</name>
    <uid>999999</uid>
  </client>'

Modify client name (application/x-www-form-urlencoded):

  curl -X PUT https://online-billing-service.com/api/v1/clients/1.xml -u [api_key]:x \
  -d 'client[name]=ClientName&client[uid]=999999'

Add product (xml):

  curl -H 'Content-Type: application/xml'
  -X POST https://online-billing-service.com/api/v1/products.xml -u [api_key]:x \
