Single Send API returned internal error


Hi, Hubspot Single-send API returned the error below (internal error") with:

I can't see anything obviously wrong with the message, the email template (which we use often and haven't changed) or the contact email -- can you look it up with correlation/requestIDs and let me know what the actual issue was? or was it a one-off, server-hiccup on your side?

Hi @jbrillante,

It's likely just a one-off error; while our error rates are extremely low, there's always the possibility of network latency or other transient issues resulting in timeouts or server errors. In general, a retry should be all it takes to resolve the error; you can include a sendId parameter with each send to make sure that you never send a duplicate email due to retry logic.

If you see errors like this persist even after retries, then it's possible there's something wrong; in cases like that, feel free to reach out here on the forum!
