Missing Configurations

1. Help Document:
   1. SAC Help Document: Add Steps to Your Multi Actions
       
   2. Limitation:
      1. Only POST method is supported
      2. Only HTTPS is supported 
          
   3. Prerequisites: 
      1. The Multi Action Service supports two OAuth authentication flows:
         1. OAuth 2.0 Authorization Code Grant:
            Please note: One of the limitations of OAuth 2.0 Authorization Code Grant, is that it generally requires the end-user to input their account/password to log in to SAC explicitly as to get the authorization code and continue the authentication process.  
            Considering the scenario where the consumption of multi-actions public API is embedded in a fully automated process with no possible user interference, you may consider the OAuth2 SAML Bearer Assertion workflow as an alternative solution.
         2. OAuth 2.0 SAML Bearer Assertion
             
      2. the access token retrieved by the "client credential" grant type is not supported by the Multi Action API
          
2. Get a Valid CSRF Token for the Multi Action API 
   
   1. Create a blank collection in Postman: 
      
       
   2. Add a Get request for CSRF, navigate to Authorization page: 
      
       
   3. Fill in Authorization page
      1. Add a New OAuth Client if you need, SAC Tenant-> System -> Administration -> App Integration -> Add a New OAuth Client
      2. Copy content
         
         1. Select Type: "OAuth 2.0".
         2. Choose Grant type: "Authorization Code".
         3. Callback URL:
            1. If you've selected "Authorize using browser", Then you will need to fill in "Redirect URI" in OAuth Client with the fixed URL "https://oauth.pstmn.io/v1/callback".
            2. If you've not selected "Authorize using browser", Then you will need to fill in both "Callback URL" and "Redirect URI" with "https://www.getpostman.com/oauth2/callback".
            3. in case of SAP Support: select "Authorizat using Browser"
         4. Fill in Auth URL: copy from "Authorization URL".
         5. Fill in Access Token URL: copy from "Token URL".
         6. Fill in Client ID: copy from "OAuth Client ID".
         7. Fill in Client Secret: copy from "Secret".
         8. Click "Get New Access Token". The login page will appear. Please log in with your account 
            
             
             
   4. After login, Click “Use Token” to get the “Access Token”
      
       
   5. Token is in use. Choose one of the following two authentication types:
      1. Oauth 2.0 Type: 
         
          
      2. “Bearer Token” Type:
         
          
   6. Fill in CSRF URL,  fill in header per Help Document: Get a Valid CSRF Token for the Multi Action API
      
       
   7. Click “Send”, if request successfully, will get x-csrf-token in header of response: 
      
       
       
3. Trigger Multi Action API 
   
   1. Add a POST request “Trigger MA API”
      
       
   2. Navigate to “Authorization”, select “OAuth2.0”, select “TokenSample” which created in step 1.4:
      
       
       
   3. Fill in API URL and Add header per Help Document:/multiActions/<multiActionID>/executions
      1. Open the Multi Action in SAC tenant, copy its “API URL”: 
         
          
      2. Fill in API URL with copied URL, add the headers, x-csrf-token’s value that comes from step 1.7: 
         
          
         
         
   4. Fill Body per Help Document: /multiActions/<multiActionID>/executions (in this sample screen shot, the multi action does not have parameter)
      
       
   5. click Send, if URL triggers successfully, get return value including “executionID”
      
       
       
4. Query the execution status of a triggered Multi Action
   1. Add a Get request for Querying status, navigate to “Authorization”, select “OAuth2.0”, select “TokenSample” which created in step 1.4:
      
       
   2. Enter URL by copy “executionID” from step 2.5.( copy “Polling API URL” as Step 2.3.1, replace <executionId>)
