Step 1 – Create a Power Automate Flow
Go to https://make.powerautomate.com/ and choose your environment that you want your flow to run. Select Create from the left navigation. Select “Instant cloud flow” and choose “When a HTTP request is received” as your trigger.
To send data to your flow, you need to generate your input schema. If you don’t have a schema, the flow trigger generates you one based on your sample payload. Expand your trigger action and click “Use sample payload to generate schema” and fill with your sample json string that you will send later.
Step 2 – Copy Your “HTTP POST URL”
When you save your flow, your trigger action will generate a “HTTP POST URL” to call your flow. We will use that URL to send POST request from our code.
