Webhooks 101 - Help

[Anonymous]

I am trying to test a webhook to call data from a external source.  I would like to make sure the existing Marketo lead data (sample of 90 records in a smart list) calls the webhook and populates the lead records with the missing data values (eg. address, phone, Duns #) for the respective fields. 

I also want to verify the datal which coming from the webhook before it writes/updates the Marketo database. Has anyone had to do this before?  

I have the webhook and smart list.  But, do I have to create a form?  How do I invok the trigger (smart campaign) to call the webhook?

Input and feedback is greatly appreciated!

We have documentation on Webhooks available here:
http://developers.marketo.com/documentation/webhooks/


The webhook is used to call a third-party server. You can trigger a webhook based on a change in a lead record. You are just notifying that server that something happened in Marketo. 

Once the server receives this notification via a webhook that something happened, you then would have to set up some logic on your end to use the Marketo APIs to update that lead record that changed. This can be accomplished either via SOAP or REST APIs.

I have an extension to this situation, where the webhook is being used in change data value flow step.  The data is not updating quickly enough to immed post in the webook.  Even with a 5 min wait step
Any suggestions
