Formatting Request Payload as an Array rather than a Hash

demontoya — Fri, 28 Feb 2025 06:28:40 GMT

I am trying to format a request payload to be an array of objects, but it appears that the payload HTTP method defaults to formatting it as a hash such as

{ email: "exampleemail", name: "John Jacob Jingleheimer Schmidt" }

However, it needs to be enveloped in an array like as follows:

[ { email: "exampleemail", name: "John Jacob Jingleheimer Schmidt" } ]

The payload HTTP method does not accept arrays, as this will throw an error. Is there a way to do this? What are your thoughts on this?

I just tested this and the HTTP request payload (specifically for a POST) will accept an array without issue. You may be encoding it incorrectly. Can you provide more details on the error you receive?

I tried enveloping the hash in an array in the following manner:

request_payload = {"data" => {"email" => "exampleemail", "name" => "John Jacob Jingleheimer Schmidt"}} arrayed_req_payload = [request_payload['data']] post(url).payload(arrayed_req_payload || {})

But I get an error saying undefined method `to_hash' for [nil]:Array at line: xxx where the line is the payload method. It's as if it is trying to convert it to a hash.

Ah, you're in the connector SDK. This is interesting...

Looking at the SDK docs, it does indeed look like it's trying to hash whatever you put inside payload. I recommend checking with support about this. Sorry I couldn't be more help!

No worries! I appreciate you looking into this!

Hi @demontoya ,
Could you please do the below modification in your code:

post(url).payload(arrayed_req_payload.to_json).headers("Content-Type" => "application/json")

Please let me know if that worked for you.

Thanks and Regards,

Thank you for the suggestion! This did not work, giving a similar error message as before: undefined method `to_hash' for #<String:0x0...>

Found a solution to this - quite silly now that I think about it.

Since the payload method does not support an array as an argument, I looked at the SDK Reference > HTTP Methods docs yet again, and realized that I could also pass arguments directly within the verb methods such that:

request_payload = {"data" => {"email" => "exampleemail", "name" => "John Jacob Jingleheimer Schmidt"}} arrayed_req_payload = [request_payload['data']] post(url, arrayed_req_payload)

This successfully passed the arrayed payload into the request body. Thank you all for your help and contribution!
