Creating Collections

This source file makes use of a series of sample helper functions that completes the entire flow of getting data needed to create a collection:

These helper utilities can be found in the Getting Started Exercise or by accessing them directly:

Each of these Helpers perform a specific function to assist in API calls such as creating collections where data (especially ID's) is needed that isn't accessible otherwise.

Process

The sequence diagram below shows the typical process to create collections.

const HttpUtil = require('../util/http');

 // Extract Parameters from Request
 const { endpointUrl, apiKey, authorization, accessToken, collection } = request;
 const { collectionType } = collection;
 // Prepare Request Body
 const body = {
   collectionType,
   name: collection.name,
   metadataTemplateId: collection.metadataTemplateId,
   metadataDocument: collection.metadataDocument || '[]',
   securityTemplateIds: collection.securityTemplateIds,

 // Get Body Content Length
 const bodyLength = Buffer.byteLength(JSON.stringify(body));
 // Prepare HTTP Request

   headers: {
     Accept: 'application/json',
     Authorization: authorization,

     'Content-Type': 'application/json',
     'x-api-key': apiKey,
   },
   body,

 // Send HTTP Request, Get HTTP Result
 const result = await HttpUtil.sendHttpRequest(httpRequest);
 // Extract Collection from HTTP Result
 const newCollection = result.body;
 // Return Collection
 return newCollection;
