Multi-request loop
Number of APIs: 3
This Collection gets a list of IDs, then loops through 3 POST requests that submit these IDs until there are none left.
The layout is as follows:
GET ID list: https://Qodex-echo.com/get
Description: - response contains an array of numbers to use as dummy data.
Test script:
- Parse IDs out of JSON, and store them as an array
- JSON.stringify() the array and store in an environment using pm.environment.set('key',value);
- Store the length of the array in the environment
1st POST request: https://Qodex-echo.com/post?test1={{id}}
Description: - A request meant to do something with the IDs we get in the GET ID list request. - Also contains a pre-request script that is critical for looping through the data above
Pre-request script:
- Check for/declare a counter variable in the environment using pm.environment.has('key'), and pm.environment.set('key',value) (this is so you can iterate through the array you stored when looping requests)
- Parse the array stored in the environment, and set value for the {{id}} variable based on the index of the array you're iterating through
- Increment your counter, and update the environment variable with the new value (pm.environment.set('key',value);)
2nd POST request: https://Qodex-echo.com/post?test2={{id}}
Description: - A request meant to do something with the IDs we get in the GET ID list request.
3rd POST request: https://Qodex-echo.com/post?test3={{id}}
Description: - A request meant to do something with the IDs we get in the GET ID list request. - Also contains a test script, which facilitates the looping of the 3 get requests in this Collection.
Test script:
- Check the length of the parsed array against your counter variable, and if there are more indexes use Qodex.setNextRequest('request_name') to loop back to the 2nd request in the Collection.
