Postman send multiple requests - postman

Question

I've got a PATCH request that looks like this:
{{host}}/api/invoice/12345678/withdraw
host is a variable determining the environment.
For this request I need to add a unique authorization token.
The problem is I need to send dozens of such requests. Two things change for each request:
id of invoice (for this case is '12345678')
auth token (herebetoken1).
How can I automate it?

Answer 1

You can use Postman Runner for your problem. In Runner, you can send specified requests in specified iterations and delay with data (json or csv file).
For more info, I suggest you take a look at the links below.

Answer 2

use the below pre-request script , and call replace id in url and auth in authorization with {{id}} and {{token}} variables . Use collection runner to execute it .
Replace the hashmap with what you requires
hashmap = {
"1234": "authtoken1",
"2222": "authtoken2"
}
pm.variables.get("count") === undefined ? pm.variables.set("count", 0) : null
let keyval = Object.entries(hashmap)
let count = pm.variables.get("count")
if (count < keyval.length) {
pm.variables.set("id", keyval[pm.variables.get("count")][0])
pm.variables.set("token", keyval[pm.variables.get("count")][1])
pm.variables.set("count", ++count)
keyval.length===count? null:postman.setNextRequest(pm.info.requestName)
}
