Salesforce REST API

This post describe about the salesforce rest api and using salesforce rest api .


Salesforce implements the OAuth to authenticate soap and rest calls with the client. So I will describe with the simple steps, how to create salesforce app that expose outside to authenticate and call rest methods.

  • First you need to create a salesforce developer account if you don't have an developer account or sandbox account. If you don't have an developer account go with the following link and create an account. It's free.   https://developer.salesforce.com/signup.
    Once you create the developer account go to https://login.salesforce.com/ and login with your credentials.
       
  • Navigate to setup and type app and you will be able to find Apps section and click the link.
  • So now you will be able to find Connected Apps section and click New. What we doing here is creating a connected app and that app will exposing to outside to authenticate and call rest api calls.
  • So you can insert Connected App Name , API Name , Contact Email and make sure you have checked Enable OAuth Settings in API (Enable OAuth Settings). We can ignore other fields for now. Once you click the Enable OAuth Setting check box you have to fill Callback URL , that will return if the request success. So you can set https://login.salesforce.com for the Callback URL.For the Selected OAuth Scopes Give Full access(full). If you need to set the permission for the api requests you can set it here. And click Save , it will take 2- 10 minutes to make those changes take effect.
            



  • After Click Continue you will be able to see a screen same as below screen.
 

  • We have created the Connected App. So now we can make rest calls to salesforce from outside via  the connected app. Here we using Username-Password OAuth Authentication Flow to authenticate with our connected app , there for we should have grant_type , client_id , client_secret , username , password parameters with the request. I will explain each parameters and endpoint URL in next post.
