A FlowBoost Community key allows 50,000 calls per month, free forever. How do you know when it’s time to upgrade to Standard? Just use Marketo’s own Send Alert feature!
When you go over the limit, the webhook call returns an HTTP 429 and Limit Exceeded:
You can detect that situation via Webhook is Called:
Then Send Alert in the flow. (You’ll get alerted for every call once you’re over the limit, but hey, that keeps the pressure on.)
P.S. To request an upgrade, send an email to support@teknkl.com. Moving to Standard is near-instantaneous: you just get a key that starts with std: instead of com: and an invoice.😀
And remember, FBSelf.usage returns your remaining calls for the month.
