How to pass SharePoint Item ID from one flow to another using HTTP

[silvana1]

I want users to click on an item in a SharePoint List and run a flow. I want this 1st flow to trigger a second flow to run. 
Can someone direct me to/share the code for how to pass the item ID from one flow to another using HTTP?

Here's what I tried. However I could not get an items in 2nd flow:
1st flow:

Trigger: "For a Selected Item".
I entered values for SP site and list.
Action: HTTP:
Method = POST
URI: copied from trigger in 2nd flow
Body: 
{
"ID": "@{triggerBody()?['entity']?['ID']}"
]
2nd flow:

 Trigger: "When a HTTP request is received".
Request Body:
{
"type": "object",
"properties": {
"ID": {
"type": "string"
}
}
}

Action: Get Item
ID: ID field from the trigger. 

Thanks!

Hi

In your HTTP request from your first flow, you should use this instead

"@{string(triggerBody()?['entity']?['ID'])}"

or

declare ID as integer on your second flow's trigger, and remove the doublequotes surrounding @triggerBody()?['entity']?['ID'] on your first flow

I tend to use the second approach

Hope this helps

Hi @silvana1 ,

Have you had an opportunity to apply @efialttes 's recommendations to adapt your Flow?

In the second Flow, when defining the request body, you need to change the ID type to integer.

The type of Item ID is actually Number instead of String.

Please take a try.

Best Regards,
