Does the HTTP Request Support Repeated Query Parameters?

In HTTP requests, is there any support for the same query parameter being repeated? I tested this and it seems to ignore all but one of the values. The api I’m calling is Retrieve Email Statistics for Categories | SendGrid Docs | Twilio and I’m trying to pass two values such as https://api.sendgrid.com/v3/categories/stats?categories=email1&categories=email2…. I assume this can only be accomplished with a code step.

Try this: ?categories[]=email1&categories[]=email2

Sorry, I didn’t specify that I was trying in the UI

the resulting call ignores all but the last categories parameter

5

Yeah, try adding the brackets afterwards.

do you mean like this?

i also tried adding brackets after on separate lines but that fails on the other end saying missing the parameter entirely

8

for now, i can do it in code or in separate calls, just wondering if it’s possible without doing that

Looks like this might be a bug in how Pipedream handles the parameters.

Interestingly enough, Zapier won’t let you do this either. They automatically dedup the parameters if you add the same one more than once - adding numbers after

: Yeah, this is pretty easy to reproduce with a workflow that calls itself (warning: don’t deploy this as it will create an infinite loop! :sweat_smile:)

Looks like there’s no standard way of doing this though! :open_mouth:

I always assumed using square brackets was a standard. :man-facepalming:

13

Ya, I have definitely seen it done a few different ways

14

can’t remember which api it was but some one that URI encoded the comma between values such as ?cars=Saab%2CAudi

15

or maybe it was a pipe :rolling_on_the_floor_laughing:

I wonder if it’s an axios thing

import fetch from "node-fetch";

export default defineComponent({
  async run({ steps, $ }) {
    return await fetch("https://eochz1eod3cid1k.m.pipedream.net?test=value1&test=value2");
  },
});

Our HTTP action uses axios, but above I’m using node-fetch

18

Ah! Might be.

FYI: You don’t need to import node-fetch anymore.

It’s native now (experimental since version 18, and stable since version 21).

Oh yea good call
