What are some examples of Outbound integration points? - ✔️✔️1.) Outbound
Messages (Workflow Action)
2.) SOAP services for invoking external web services (i.e. apex classes generated from
a WSDL provided by/from/for a third party external application)
3.) HTTP to invoke external REST services
4.) Email
When creating an Apex Web Service, what two annotations are required? - ✔️✔️1.)
The Apex class must be *global*
2.) The class method must be annotated with *webservice* and *static*.
For example:
global class MyWebServices {
webservice static Id createContact(String lName, String accId){
Contact c = new Contact(LastName = lName, AccountId = accId);
insert c;
return c.Id;
}
}
Creating an Apex Web Service is an example of what type of Integration (i.e. Inbound or
Outbound) - ✔️✔️Inbound
For an Apex Web Service that you created, how can an external client call the web
service? What is required? - ✔️✔️1.) Generate the WSDL for the service by navigating
to the Apex class in your environment and clicking on *Generate WSDL*.
2.) Provide the WSDL to the developer or owner of the external client for use with the
language of their choice.
What are examples of things that the Salesforce platform handles for you automatically
when creating Apex Web Services? - ✔️✔️1.) The platform hosts the service for you.
2.) The platform handles the argument and return value conversions for you.
3.) The platform generates the WSDL for you.
When creating an Apex Web Service, what is the only thing you need to actually worry
about? - ✔️✔️Creating the business logic in Apex. The platform handles everything
else for you, such as hosting the service, argument and return type value conversions,
,and even generating the WSDL that needs to be consumed by the external client
application. Thanks Salesforce! ;)
What are some examples of Inbound integration points? - ✔️✔️1.) Creating and
Hosting Apex REST and Web Services
2.) Email
3.) The standard Salesforce SOAP and REST APIs
4.) Chatter REST API
What are the steps involved to generate SOAP services for invoking external web
services? - ✔️✔️1.) Obtain a WSDL for the SOAP service with which you would like to
integrate.
2.) Navigate to Setup > Apex Classes > Generate from WSDL
3.) Upload the WSDL.
4.) The WSDL will be parsed, and if parsing is done successfully without any errors,
Apex classes will be generated for each namespace that appears in the WSDL
document. These Apex classes can then be used to integrate with the SOAP service.
What is an example of a scenario where, when using the "Generate from WSDL" action,
the WSDL parsing may fail? - ✔️✔️If the WSDL contains an unsupported schema type.
How can you convert Apex methods that invoke web services (i.e. those generated from
a WSDL) from synchronous actions to asynchronous actions? - ✔️✔️Annotate the
methods with @future. You can then monitor the callout under Setup > Monitoring >
Apex Jobs
How many notifications may be included in one Outbound Message? - ✔️✔️100
Outbound Messages are asynchronous or synchronous? - ✔️✔️Asynchronous
What are some elements included in the payload of an Outbound Message? - ✔️✔️1.)
The Org Id
2.) An IP address
3.) A session Id
4.) Enterprise/Partner Endpoint URL
# 1 and # 2 aid with security as you can verify the source of the message, while # 3 and
# 4 provide easy callbacks to the Salesforce platform.
What are the steps involved with setting up an Outbound Message? - ✔️✔️1.) Define
your Workflow Rule or Approval Process
2.) Define the Outbound Message Workflow Action
3.) Download the WSDL for the Outbound Message.
, 4.) Use the language of your choice to implement the endpoint to receive the Outbound
Message.
Bonus 5.) Ensure that your endpoint server has been added under Remote Site
Settings.
Is it possible to track the status of an Outbound Message? - ✔️✔️Yes, under Setup >
Monitoring > Outbound Messages
Describe the details with respect to Notifications for Outbound Messages. - ✔️✔️1.) If
the endpoint is unavailable, messages will stay in the queue until sent successfully, or
until they are 24 hours old. After 24 hours, messages are dropped from the queue.
2.) If a message cannot be delivered, the interval between retries increases
exponentially, up to a maximum of two hours between retries.
3.) Messages are retried independent of their order in the queue. This may result in
messages being delivered out of order.
4.) Because a message may be delivered more than once, your listener client should
check the notification IDs delivered in the notification before processing.
5.) Note that if the information in the object changes after the notification is queued but
before it is sent, only the updated information will be delivered.
What three classes are involved with making HTTP requests to an external REST
service? - ✔️✔️1.) Http
2.) HttpRequest
3.) HttpResponse
What is the Http class used for? - ✔️✔️The Http class is used to initiate an HTTP
request and response.
What is the HttpRequest class used for? - ✔️✔️The HttpRequest class is used to
define the request. It is used to create GET, POST, PUT, and DELETE requests,
manipulate request headers, configure timeouts, and more.
What is the HttpResponse class used for? - ✔️✔️The HttpResponse class is used to
handle Http responses, including determining Http response codes, response headers,
and content in the response body.
What are the primary classes to use for outbound Email messaging? - ✔️✔️1.)
SingleEmailMessage
2.) MassEmailMessage
3.) Messaging
