How to use API PostMan

Creating a collection

• To create the collection in postman we need to add the collection link in import  https://www.getpostman.com/collections/946ded4610702c170e87

• As shown in the below screenshot, we need to add the link and click on continue.

• After that it will ask to confirm the import as below shown.

• After importing the collection, it will appear in the left side of the postman.

• All the details which is their in ASTPP system will be define from this collection

Creating an Environment

• On the right side there is "No Environment " option and one symbol also, we need to click on eye symbol as shown in below screenshot in order to create the environment .

• Click on the Add Environment

• After that as shown below, here you need to add  Variable, Initial vale and current value.

• Variable and initial values are same for all the system, we need to add common variable and initial value like below:

• You need to add auth token as:- 

             x_auth_token - nOcBurg5KvyurOri8A9ds3rXWafZ99Du

• Then after add the URL of your portal:-   

              api_url - https://3.109.3.164/

• Token will generate after we login the admin account of the given URL

How to login in portal through API

• You need to add this path:   {{api_url}}/api/login/    in the post section as shown in below screenshot, then click on body field from the below mentioned fields.
• There you can see the JSON format code , you need to add username and password .
• Then click on the SEND which is there in Blue colour.

• After clicking on SEND button, you will see if the code run successfully or not.
• If it will run successfully it will generate on the right side as true, as shown in the below screenshot.

• After successfully login in to the admin portal, there is one token on the right side of the postman where we got status:"true", we can find the token for it in the last few lines of our response, as shown below.

• We can add this token in our environment which we create above in  third section of token.
• If the code will not run successfully it will generate false error on the place of true, it means that login is unsuccessful.

Three reasons for unsuccessful login

• First of all if we do not have installed API addon in portal then it will run the below error.

• If the addon is installed then we need to check the Auth token, if that is added wrongly then it will run the below error.

• Then we need to check the URL , if that is added wrongly then it will run the below error.
