Recently we were working on Facebook Leads integration with Dynamics 365. Webhook for Leads can be configured to send real-time notifications of the Leads ads changes.
The first step of setting up Webhook requires creating an HTTPS endpoint that can process 2 types of HTTP Requests – Verification and Event notifications.
Here we will see how to configure the Power Automate flow for verification.
Login to Meta for Developers – Facebook and create an app.
It asks us to specify the Callback URL and Verify token.
Back in Power Automate create a Flow with Request type Trigger, followed by Parse JSON and Response actions.
For HTTP Request, select GET as the method, as FB will send a GET request to the endpoint URL, with the verification requests included in the endpoint of the URL.
Next, Parse the JSON and specify the Content and Schema
Content –
triggerOutputs()['queries']
Schema –
Lastly in Response, set Status Code as 200 and Body as hub.challenge.
Here FB expects the Endpoint to verify the hub.verify_token (which we haven’t set up yet) and respond with hub.challenge value after verification.
Save the Flow, and copy the URL generated for the HTTP Request trigger.
Back in Meta for Developers, in edit user subscription paste the Callback URL and for now in place of token specify any value and click on Verify and Save.
We should now have a Webhook endpoint (Flow) successfully configured
We got the below error while trying to create a quote product programmatically.
As the error message specifies, this is because we are trying to add/associate a DRAFT product to the Quote Product.
We will get a similar error from the application as well if we try adding a draft product as an existing product to either a quote product or an opportunity product.
