- Then another prompt appear where you can see your Access token. Then click on Use Token button. Now you successfully Connected your Salesforce org
Let’s Create Custom field for Opportunity object
- Firstly we have to Create New RestResource Annotation enabled Apex Class in Salesforce Org. Please Referred below apex class
@RestResource(urlMapping = '/Customfields')
global class CreateCustomfields
{
@HttpPost
global static Map<String,String> GenerateCustomfields(String fieldType,String ObjectName,boolean Required,integer length,String label,String description,String inlineHelpText)
{
Map<String,String> Resp = new Map<String,String> ();
HttpRequest request = new HttpRequest();
request.setHeader('Authorization', 'Bearer ' + UserInfo.getSessionID());
request.setHeader('Content-Type','application/json');
request.setEndpoint(URL.getSalesforceBaseUrl().toExternalForm()+'/services/data/v56.0/tooling/sobjects/CustomField/');
request.setMethod('POST');
if(fieldType == 'Text')
{
request.setBody('{"Metadata" : {"type" : "'+fieldType+'","description" : "'+description+'", "inlineHelpText" : "'+inlineHelpText+'","label" : "'+label+'","length" : '+length+',"required" : '+Required+'}, "FullName" : "'+ObjectName+'.'+label.replace(' ','_')+'__c"}');
}
else
{
Resp.put('Error','Please provide field type');
return Resp;
}
Http http = new Http();
HTTPResponse res = http.send(request);
if(res.getStatusCode()==200 || res.getStatusCode()==201)
{
Resp.put('Success','status: '+res.getStatus()+' Status Code: '+res.getStatusCode());
Resp.put('StatusCode',''+res.getStatusCode());
Map<String, Object> m = (Map<String, Object>) JSON.deserializeUntyped(res.getBody());
Resp.put('requestgetBody',URL.getSalesforceBaseUrl().toExternalForm()+'/lightning/setup/ObjectManager/'+ObjectName+'/FieldsAndRelationships/'+''+m.get('id')+'/view');
}else
{ String body=res.getBody();
Resp.put('Error',''+res.getStatus());
Resp.put('StatusCode',''+res.getStatusCode());
body=body.substring( 1, body.length() - 1 );
map<String,object> m = (map<String,object>) JSON.deserializeUntyped(body);
Resp.put('ErrorMessage',''+m.get('message'));
Resp.put('Endpoint',''+request.getEndpoint());
}
return Resp;
}
}- Enter your Salesforce URL + /services/apexrest/Customfields in URL Section and Select method type as POST
- Now click on Body section select format as raw type as a JSON and enter following scrip in below section

"fieldType" : "Text",
"ObjectName" : "Opportunity",
