Description

Access historical and current market data by creating a universe of securities.

Create a Bloomberg Hypermedia connection object by using the API key provided by Bloomberg.

credentialsString = '{"client_id":"89beaeab724bbdf5e186b733c58af2","client_secret":"77050429aee81eb31793fb10fa4301c54911db545de8b2990252ffe2b56b11","name":"BloombergHAIDevelopment","scopes":["eap","beapData","reportingapi"],"expiration_date":1699198358934,"created_date":1651764758934}'
c = bloombergHypermedia(credentialsString)
c = 
 
  bloombergHypermedia with properties:

      TimeOut: 200.00

Specify your catalog ID and create the payload structure that holds the essential query information required by the Bloomberg Hypermedia data server. Replace "123" with your login credentials for the catalog you want to access.

userCatalog = "123";
payload.type = "Universe";
payload.identifier = "u" + bloombergHypermedia.generateResourcePostfix;
payload.title = "Test Universe";
payload.description = "Test historical data universe";
payload.contains.type = "Identifier";
payload.contains.identifierType = "TICKER";
payload.contains.identifierValue = "XYZ US Equity";

Use the createUniverse function to create the universe for the Hypermedia connection.

[universeID,response] = createUniverse(c,userCatalog,payload)
universeID = 
  
    "u2022052413354920f366"
  
response = 
  
    ResponseMessage with properties:
  
      StatusLine: 'HTTP/1.1 201 CREATED'
      StatusCode: Created
          Header: [1×14 matlab.net.http.HeaderField]
            Body: [1×1 matlab.net.http.MessageBody]
       Completed: 1

You can use the universe ID to create a data request using the createRequest function.
