That is a lot of people to run through a webhook in one batch. And saying this as someone who runs 50,000-100,000 webhooks a day on a few Marketo instances: 900,000 is way too much. If I wouldn’t do it, you shouldn’t do it!
As it’s a one-time batch it’s feasible, don’t get me wrong. You just aren’t going to get it done in one day. It’ll likely be running for a few days.
What you should do instead is use their bulk/List API, not their webhook/Single API, for one-time backfill.
But what you still haven’t supplied is exactly how it “doesn’t work” in Single mode — what does the Call Webhook activity return? Show the Activity Log Detail, please.
hi sorry for not sharing this before, also we are okay doing it in batches like 50k a day also works
got it thanks
the API call worked what should we do to populate it back in marketo custom field with the validation result
You use Response Mappings to map JSON properties like result
and suggested_correction
to Marketo fields.
it worked thanks a ton
