Anthopic (Claude) Raw JSON Integration

I authorize Pabbly Support to log in to my account and make changes to the specified workflow for troubleshooting.

I am trying to create a workflow that sends a POST request to the Anthropic (Claude) Messages API:

https://api.anthropic.com/v1/messages

Anthropic requires a nested JSON request body with arrays, like:
{
"model": "claude-3-sonnet-20240229",
"max_tokens": 100,
"messages": [
{
"role": "user",
"content": [
{
"type": "text",
"text": "Say the word HELLO."
}
]
}
]
}

However, when I use API by Pabbly, and select:

• Method: POST
• Payload Type: JSON

…I do NOT get a raw JSON editor.

Instead, Pabbly only shows the Set Parameters section (key/value pairs), which cannot produce the nested JSON required by Anthropic.



I watched your video “How to Use Anthropic (Claude) Inside Pabbly Connect,” but my account does NOT show:

1. The dedicated Anthropic (Claude) app
2. The Raw JSON Body text area under “Payload Type: JSON”

This prevents me from integrating Anthropic at all.

My Question​

Can you please enable one of the following for my account:



A) The dedicated “Anthropic (Claude)” app,

OR

B) The Raw JSON request body editor under “API by Pabbly” → Payload Type: JSON



Without one of these features, I cannot send a valid Anthropic request.



Here is a screenshot showing that the Raw JSON editor does not appear in my interface:



(attach your screenshot: the one showing Payload Type JSON with NO big text box)



Thank you — I appreciate your help.
