It seems URLs longer than 512 characters causes adding new webhook subscriptions to fail; however, I don’t see this character limit mentioned in the documentation. Can you confirm that 512 characters is the maximum length for a webhook URL, and if so, that it will not be possible to extend this? ---

Hi @TSullivan, Apologies for getting back to you late on this. Yes, 512 is the max length for the webhooks subscription URL. We likely won’t extend the length unless it’s a blocker for our clients. Is there a reason you would require a longer field? ---
