How to retrieve Create Date and Modified date of all fields of a custom object using Apex or Api
Hi guys,
I am new to Apex and APIs. I am trying to retrieve Create Date and Modified date of all fields of a custom object. I have already tried the below
https://developer.salesforce.com/docs/atlas.en-us.api_rest.meta/api_rest/dome_sobject_describe.htm
When I paste the below API request in the browser
https://xxxx.salesforce.com/services/data/v20.0/sobjects/Account/describe/ -H "Authorization: Bearer xxxxxxxxxxxxxxxxxxxxxxxxxx"
I get an error saying "This XML file does not appear to have any style information associated with it. The document tree is shown below.
<errorCode>INVALID_SESSION_ID</errorCode>
<message>Session expired or invalid</message>
"
Does this work for custom objects? Can someone point full material for this (how to include additional parameters in the API request etc)
1 Ans-
You have to do a API call. It cannot be done by pasting the URL on browser.
First you have to get the access token then you have to do a callout.
Something like this:
Http h1 = new Http(); HttpRequest req1 = new HttpRequest(); req1.setHeader('Authorization','Bearer '+YOUR_ACCESS_TOKEN); req1.setHeader('Content-Type','application/json'); req1.setMethod('GET'); req1.setEndpoint('https://xxxx.salesforce.com/services/data/v37.0/sObjects/Account/describe'); HttpResponse res1 = h1.send(req1);2 Ans-
Yes it will work for standard as well as custom objects.
One more URL for you -
