Calendar

API for a tool to craftsmen used to register working hours, material usage and quality assurance. # Endpoint The endpoint `https://app.apacta.com/api/v1` should be used to communicate with the API. API access is only allowed with SSL encrypted connection (https). # Authentication URL query authentication with an API key is used, so appending `?api_key={api_key}` to the URL where `{api_key}` is found within Apacta settings is used for authentication # Pagination If the endpoint returns a `pagination` object it means the endpoint supports pagination - currently it's only possible to change pages with `?page={page_number}` but implementing custom page sizes are on the road map. # Search/filter Is experimental but implemented in some cases - see the individual endpoints' docs for further explanation. # Ordering Is currently experimental, but on some endpoints it's implemented on URL querys so eg. to order Invoices by `invoice_number` appending `?sort=Invoices.invoice_number&direction=desc` would sort the list descending by the value of `invoice_number`. # Associations Is currently implemented on an experimental basis where you can append eg. `?include=Contacts,Projects` to the `/api/v1/invoices/` endpoint to embed `Contact` and `Project` objects directly. # Project Files Currently project files can be retrieved from two endpoints. `/projects/{project_id}/files` handles files uploaded from wall posts or forms. `/projects/{project_id}/project_files` allows uploading and showing files, not belonging to specific form or wall post. # Errors/Exceptions ## 422 (Validation) Write something about how the `errors` object contains keys with the properties that failes validation like: ``` { "success": false, "data": { "code": 422, "url": "/api/v1/contacts?api_key=5523be3b-30ef-425d-8203-04df7caaa93a", "message": "A validation error occurred", "errorCount": 1, "errors": { "contact_types": [ ## Property name that failed validation "Contacts must have at least one contact type" ## Message with further explanation ] } } } ``` ## Code examples Running examples of how to retrieve the 5 most recent forms registered and embed the details of the User that made the form, and eventual products contained in the form ### Swift ``` ``` ### Java #### OkHttp ``` OkHttpClient client = new OkHttpClient(); Request request = new Request.Builder() .url("https://app.apacta.com/api/v1/forms?extended=true&sort=Forms.created&direction=DESC&include=Products%2CCreatedBy&limit=5") .get() .addHeader("x-auth-token", "{INSERT_YOUR_TOKEN}") .addHeader("accept", "application/json") .build(); Response response = client.newCall(request).execute(); ``` #### Unirest ``` HttpResponse<String> response = Unirest.get("https://app.apacta.com/api/v1/forms?extended=true&sort=Forms.created&direction=DESC&include=Products%2CCreatedBy&limit=5") .header("x-auth-token", "{INSERT_YOUR_TOKEN}") .header("accept", "application/json") .asString(); ``` ### Javascript #### Native ``` var data = null; var xhr = new XMLHttpRequest(); xhr.addEventListener("readystatechange", function () { if (this.readyState === 4) { console.log(this.responseText); } }); xhr.open("GET", "https://app.apacta.com/api/v1/forms?extended=true&sort=Forms.created&direction=DESC&include=Products%2CCreatedBy&limit=5"); xhr.setRequestHeader("x-auth-token", "{INSERT_YOUR_TOKEN}"); xhr.setRequestHeader("accept", "application/json"); xhr.send(data); ``` #### jQuery ``` var settings = { "async": true, "crossDomain": true, "url": "https://app.apacta.com/api/v1/forms?extended=true&sort=Forms.created&direction=DESC&include=Products%2CCreatedBy&limit=5", "method": "GET", "headers": { "x-auth-token": "{INSERT_YOUR_TOKEN}", "accept": "application/json", } } $.ajax(settings).done(function (response) { console.log(response); }); ``` #### NodeJS (Request) ``` var request = require("request"); var options = { method: 'GET', url: 'https://app.apacta.com/api/v1/forms', qs: { extended: 'true', sort: 'Forms.created', direction: 'DESC', include:
