But when we started work on Nova, we looked at where the web was today, and where we needed to be. It was time for a fresh start. It all starts with our first-class text-editor. It's new, hyper-fast, and flexible, with all the features you want: smart autocomplete, multiple cursors, a Minimap, editor overscroll, tag pairs and brackets, and way, way more. For the curious, Nova has built-in support for CoffeeScript, CSS, Diff, ERB, Haml, HTML, INI, JavaScript, JSON, JSX, Less, Lua, Markdown, Perl, PHP, Python, Ruby, Sass, SCSS, Smarty, SQL, TSX, TypeScript, XML, and YAML. -

JSON
JSON
JSON (JavaScript Object Notation) is a lightweight data-interchange format. It is easy for humans to read and write. It is easy for machines to parse and generate. It is based on a subset of the JavaScript Programming Language Standard ECMA-262 3rd Edition - December 1999. JSON is a text format that is completely language independent but uses conventions that are familiar to programmers of the C-family of languages, including C, C++, C#, Java, JavaScript, Perl, Python, and many others. These properties make JSON an ideal data-interchange language. JSON is built on two structures: 1. A collection of name/value pairs. In various languages, this is realized as an object, record, struct, dictionary, hash table, keyed list, or associative array. 2. An ordered list of values. In most languages, this is realized as an array, vector, list, or sequence. These are universal data structures. Virtually all modern programming languages support them in one form or another.Starting Price: Free -

Newsletter2go
Newsletter2Go
Welcome and thanks for using Newsletter2Go. Our REST API exchanges data in the JSON data format. Every parameter/payload you pass (with very few exceptions, e.g., when you upload files) should therefore be formatted in JSON and our API will always return results in JSON as well. Our API follows a very RESTful approach. Most importantly, we support the four standard request methods for CRUD operations. A transactional mailing is a type of mailing that is highly customized, sent to a single individual at a custom time mostly through the system and triggered by an API call. One, if not the most important purpose, of using the Newsletter2Go API is to send transactional emails. Over the last couple of years we have optimized this process in order to offer this very powerful feature to single developers as well as professional teams. First, you will have to create a new mailing. -
