The Salesforce REST API is a powerful web service that lets you integrate Salesforce applications using standard HTTP methods. This can then be used to integrate Salesforce with Sage ERP<\/a>. With help of Apex REST, we can expose the data from Salesforce<\/a> orgs and we can also fetch data from other systems which hits the particular webservice(URL).Since we are exposing the data to public access with this approach so be cautious with security setups in Salesforce org.\u00a0<\/p>\n

We will use Salesforce Site as our webservice where most of the action will happen. For our demo purpose, we will create a Custom object named \u201cDemo\u201d. Once the object is created using the below code.<\/p>\n

\"Creating<\/a>

Creating Demo Object<\/p><\/div>\n

\"Apex<\/a>

Apex Class code for Demo Controller<\/p><\/div>\n

Now, create a site in Salesforce, if you are new and if you need not know how to create a site in Salesforce then refer this link<\/a>. Once your site is created in its \u201cPublic Access Settings\u201d then add the above created Class into \u201cEnabled Apex Classes\u201d and save it. Then at profile level just enable the Read, Create, Edit and Delete access to the \u201cDemo\u201d object. Now, that the configuration and coding are completed, its time to test the REST API.<\/p>\n

From your site section select the URL of your newly created site and append it with \u201cservices\/apexrest\/\u201d and URLMapping mentioned in the code at the end. Your URL must look something like this-
https:\/\/<>\/services\/apexrest\/Demo\/<\/p>\n

Now, let’s add a record from an external system to Salesforce using REST API, for this, we will be using Google’s ARC (Advanced REST Client). In the Header section Add content type as JSON and then click add body and use the below JSON as body and use \u201cPOST\u201d Method to post data from ARC to Salesforce.
JSON-
{
\u201cName\u201d: \u201cREST Demo\u201d
}<\/strong><\/p>\n

Once you execute the request then you should receive status code 200 denoting success and in response, you should receive the record id of the record just created.<\/p>\n

\"Response<\/a>

Response that record is created<\/p><\/div>\n

To verify you can simply use the \u201cGET\u201d method to fetch the data and see for yourself.<\/p>\n

So, in this way you can simply test the REST API from Salesforce.<\/p>\n\n\n
