API POST Worked For 2 Months, Now Error

Hi,

I'm sending an API POST Event which has been working for months, but suddenly fails. If I use all the API provider's default test data, it fails, but if I use PostMan, it works.

The Endpoint URL is good, but I get an error saying the documents array is not an array.

This is the JSON code that works in POSTMAN.
{
"envelope_title": "Example Envelope",
"envelope_documents": [
{
"document_title": "Example Document",
"document_url": "http://assets.signable.co.uk/SampleDoc.pdf",
"document_file_name": "test.pdf"
}
],
"envelope_parties": [
{
"party_name": "Jo Bloggs",
"party_email": "[email hidden]",
"party_role": "signer1",
"party_message": "This is a message."
}
]
}

Here is my Pabbly action:

What am I missing?

Thanks

Can you please tell us which endpoint you are trying to use?

Further, try using the "Custom Request" action step type and then try again.

You may also refer to the following video tutorial and then try again.
