On click of custom button , how can I call API ?

Question

Query : I have an API in Acconts/clients/base/api/mycustomAPI.php. On click of the button (custom button created) , it should call that API. 
 Sugar CRM version used : 10.3 
 API url :3.82.61.201/.../ 
 
 My Code: (record.js) 
 ({ extendsFrom:'RecordView', initialize:function(options){ this._super('initialize',[options]); //add listener for custom button this.context.on('button:submit_button:click', this.submit_button, this); }, submit_button:function(){ app.api.call('update',app.api.buildURL('Accounts/' + this.model.get('id') + '/mycustomAPI') ,null { success:function(fdata) { app.alert.show('success', { level: 'error', messages: 'Activated.', autoClose: false }); }, error: function(error){ app.alert.show('err', { level:'error', title: app.lang.getAppString('ERR_INTERNAL_ERR_MSG'), messages: err, autoClose: false }); }, }); } }) 
 Please help me with the code here. !!!

Sanchez Jorge Luis was right to ask you for the definition, you are missing a variable in the path for the id taht you are passing. 
 in general, the number of elements in your path need to equal the number of elements int he path vars. 
 your path should be: 
 'path' => array('Accounts', 'mycustomeAPI', ?),

Yeah and the code the api.call must be change from 'update' to 'read', because is a action type 'GET' 
 app.api.call('read', app.api.buildURL('Accounts/mycustomAPI/' + this.model.get('id')), null {

No it should have the question mark, as I stated above. 
 See: support.sugarcrm.com/.../

In postman the url must looks: 
 like:http://{{CRM_URL}}/sugarcrm/rest/v10/Accounts/mycustomAPI/62aace7c-8729-11eb-a0e4-0e1a95bf95b1 
 
 have a issue in the code, are missing one comma after position of "params" 
 app.api.call('read', app.api.buildURL('Accounts/mycustomAPI/'+model.get('id')), null, {...});

I understand that you need set a value into current model. For this task i suggest made this: 
 var self = this; app.api.call('read', app.api.buildURL('Accounts/mycustomAPI/' + this.model.get('id')), null,{ success:function(fdata) { if (fdata){ console.log("Response", fdata.account_type); self.model.set('middlename_c', fdata.account_type); // this line set value into current record console.log("Account Type", middleman); 
 app.alert.show('Activation-Initiated', { level: 'success', messages: 'Customer Is Activated', autoClose: false }); } }, error: function(error){ app.alert.show('err', { level:'error', messages: 'Customer Is Not Activated', autoClose: false }); }, });
