Easily Integrate Anthropic Claude with Power Automate — Full Demo and Guide

Описание: ✨ Prerequisites
Before you start, make sure you have:

An Anthropic API key → from https://console.anthropic.com
A Power Automate environment (any license that supports Custom Connectors)
Permission to create Custom Connectors


1️⃣ Create Your Custom Connector

Go to Power Automate → Dataverse → Custom Connectors.
Click + New Custom Connector → Create from blank.
Give it a name (e.g., Anthropic Claude API).


2️⃣ General Settings
Fill in the required details:

Scheme: https
Host: api.anthropic.com
Base URL: /v1

Save and continue.

3️⃣ Add the Security Settings
Anthropic uses API keys via headers.

Go to the Security tab.
Choose API Key.
Set:

Parameter Label: API Key
Parameter Name: x-api-key
Location: Header



Save and continue.

4️⃣ Define the API Action (Messages Endpoint)

Go to Definition.
Click + New Action.
Name it something like: Run Claude Model.
Add a description.

Add the Request

Click Import from Sample.
Select POST.
Enter the URL: https://api.anthropic.com/v1/messages

Sample Body
Use this valid sample payload (Claude 3.x uses the Messages API):


{
"model": "claude-3-sonnet-20240229",
"max_tokens": 500,
"messages": [
{
"role": "user",
"content": "Hello Claude"
}
]
}


Add Required Headers
Power Automate will detect the required headers, but make sure these exist:

x-api-key = your key

anthropic-version = 2023-06-01

content-type = application/json


Response Setup

Add a sample response.
Paste typical response JSON, for example:


{
"id": "msg_123",
"type": "message",
"role": "assistant",
"content": [
{
"type": "text",
"text": "Hello! How can I assist you today?"
}
],
"model": "claude-3-sonnet-20240229"
}

This helps Power Automate generate dynamic schema fields.
Save and continue.

Skip the test bit and just save - if you test here it will fail - instead..........

create manual flow:

add your custom connector with the following parameters:

anthropic-version: 2023-06-01

content-type: application/json

body/model: claude-3-haiku-20240307

body/max_tokens: 512

body/messages:

[
{
"role": "user",
"content": "put whatever you want to ask claude here"
}
]


add a compose action so you can see the output
