Salesforce Integration With External Systems

compare json and xml for data transfer, noting json’s lighter, faster format with arrays and open source libraries, versus xml’s extensible markup and soap constraints in rest api.

Authenticate to Salesforce using Postman by sending a soap api request to the login endpoint with username, password, security token to obtain a session id and server url for calls.

Use postman to execute soap api calls against Salesforce, authenticate with a session, and retrieve student records by posting xml queries that fetch address, class enrolled, phone, and school name.

Learn to insert multiple records into a Salesforce custom object via the soap api by posting an xml payload, including different types, with proper headers and a session id.

Learn to insert multiple records of different objects—school and student—within a single SOAP call, using a Postman XML body, proper headers, and a session header.

Expose an Apex class as a soap service by using the global keyword and decorating methods with the web service keyword and the static modifier.

Authenticate Salesforce rest api users using a connected app, client ID/secret, username, password, and security token in Postman to obtain a bearer access token and call rest endpoints.

Download and install the 64-bit Windows Node.js installer, verify installation with node -v, then download and install Visual Studio Code for Windows, including a desktop icon and start menu shortcut.

Discover how to use the Salesforce bulk API with Postman to upload large data sets by creating a job, adding batches, and performing insert, update, or delete operations.

Authenticate to Salesforce and create a bulk insert job for the student object, then upload a CSV with matching field names and monitor the job until completion.

Explore how the Salesforce streaming API keeps external systems in sync by publishing events and notifications to subscribed channels via push topics, change data capture, and platform events.

Explain push topics as channels with a criteria query, and guide creating push topics by name and query so external apps subscribe and receive notifications.

Create a push topic called student updates with a fields-based query, set api version to 49.0, and enable notifications for create, update, and delete to the external system.

Explore platform events in Salesforce, part of streaming API, and learn how event-driven architecture enables publish/subscribe notifications between Salesforce and external systems, including producers and consumers, via Apex or Workbench.

Publish platform events from Apex by creating an account platform event with name, phone, and salary fields, and use an after update trigger to publish changes to subscribers.

Learn how to enable change data capture for objects in Salesforce, subscribe external systems to create, update, and delete events, and receive notifications with record ID and change type.

Learn how to compare enterprise and partner WSDL in Salesforce, including strong vs loose typing, single Salesforce org versus multiple Salesforce orgs, and how configuration changes affect each file.

Generate apex classes from the wsdl in the parent Salesforce system by parsing the partner wsdl and the receive parameters wsdl. Replace any type with string and generate apex code.

Test SOAP, REST, and HTTP web services with SoapUI, a free open-source tool you download from soapui.org. Learn to download, install, and test APIs via a simple interface.

Shows how to invoke a child soap service from the parent Salesforce system, authenticate, obtain a session ID, and create a contact with first name, last name, title, and email.

Install the Salesforce CLI (sfdx) and the Salesforce extension pack for Visual Studio Code, then set up the environment to build a lightning web component.

Define onchange handlers for two currency comboboxes, capture selected values into fromCurrencyValue and toCurrencyValue, log them for debugging, and prepare a future conversion-rate call to the alpha one tejuco service.

Test the application by validating rest api calls from the lightning web component to the apex controller, displaying USD to INR currency conversion and the JSON response.
