Is this where I'd tell it to post to the form API? And is this the URL I'd use? /rest/asset/v1/form/{id}/field/{fieldId}.json |
Nope... that's the Marketo REST API endpoint for managing fields on forms (not populating them).
The Forms API endpoint is /index.php/leadCapture/save* on your pod.
The problem here is going to be that their webhook (like many "think they're cool" modern-era webhooks) posts only JSON-encoded data, as opposed to form-encoded data. For a very brief, example that means they send a payload like:
{
"data" : {
"event_name" : "unsubscribed",
"email_address" : "customer@example.com"
}
}
but we need
munchkinId=123-AAA-456&formid=7890&Email=customer%40example.com
on the form side.
This means you need to translate the data from (incoming) JSON to (outbound) form encoding by going through an intermediate server. This doesn't have to cost you anything to run -- you can use Amazon API Gatway, and most likely for your load it would cost only pennies per month -- but someone needs to set up the mapping.
Note there's no direct route to Marketo here. You can't post the the JSON data directly to Marketo, either. It would still need to be translated, in this case from one JSON structure to another JSON structure (not to mention authenticated). It would be far easier to build the JSON-to-form than the JSON-to-OAuth-to-JSON (and like I mentioned the latter has major API limits).
