The Wolfram Language has built-in capabilities for creating and deploying APIs on the web and elsewhere.

Basic API Setup

APIFunction — define the parameters and function to execute for the API

CloudDeploy — deploy as an active API on the web

Handling Parameters »

Interpreter — specify how parameters should be converted for use in the function

Failure — object returned if interpretation fails

Controlling API Results

ExportForm — specify a format for results (e.g. "PNG", "CloudCDF", ...)

ResponseForm — specify a wrapper for the API response (e.g. "JSON")

HTTPResponse — specify metadata from the HTTP response (e.g. "StatusCode")

HTTPErrorResponse — specify an HTTP error response

Constructing Results

GenerateDocument  ▪  XMLTemplate  ▪  EmbeddedHTML  ▪  Manipulate  ▪  ...

Execution Metadata »

$GeoLocation  ▪  $GeoLocationCountry  ▪  $UserAgentString  ▪  $RequesterAddress  ▪  HTTPRequestData  ▪  ...

Embedding in External Constructs

EmbedCode — generate code for embedding API calls in pages, languages, etc.

Managing Instant APIs

CloudObject — symbolic representation of APIs in the cloud

Options, SetOptions — find, set options for a deployed API

Permissions — permissions for executing or modifying the API

Testing Instant APIs

URLExecute  ▪  URLBuild  ▪  CloudFunction

GenerateHTTPResponse — generate a symbolic HTTP response from an APIFunction
